This power module can be used in a wide variety of applications, ranging from simple standalone operation to an integrated part

of sophisticated power architectures. To preserve maximum flexibility, internal fusing is not included, however, to achieve

maximum safety and system protection, always use an input line fuse. The safety agencies require a time-delay fuse with a

maximum rating of 8 A (see Safety Considerations section). Based on the information provided in this data sheet on inrush energy

and maximum dc input current, the same type of fuse with a lower rating can be used. Refer to the fuse manufacturer’s data sheet

for further information.

rapid cycling of Vin from normal levels to less than the Input Undervoltage Lockout (which causes module shutdown), and then back to normal; or 2) toggling the

on/off signal from on to off and back to on without removing the input voltage. The normal Turn-On Delay interval, Tdelay, will occur whenever a module restarts with

input voltage removed from the module for the preceding 1 second.

Design Considerations

Input Filtering

The power module should be connected to a low

ac-impedance source. Highly inductive source

impedance can affect the stability of the power module.

For the test configuration in Figure 7 a 33-100μF

electrolytic capacitor (ESR<0.1 at 100kHz), mounted

close to the power module helps ensure the stability of

the unit. Consult the factory for further application

guidelines.

Safety Considerations

For safety-agency approval of the system in which the

power module is used, the power module must be

installed in compliance with the spacing and separation

requirements of the end-use safety agency standard,

i.e., UL 60950-1-3, CSA C22.2 No. 60950-00, and VDE

0805:2001-12 (IEC60950-1).

If the input source is non-SELV (ELV or a hazardous

voltage greater than 60 Vdc and less than or equal to

75Vdc), for the module’s output to be considered as

meeting the requirements for safety extra-low voltage

(SELV), all of the following must be true:

 The input source is to be provided with reinforced

insulation from any other hazardous voltages,

including the ac mains.

 One VIN pin and one VOUT pin are to be grounded, or

both the input and output pins are to be kept

floating.

 The input pins of the module are not operator

accessible.

 Another SELV reliability test is conducted on the

whole system (combination of supply source and

subject module), as required by the safety

agencies, to verify that under a single fault,

hazardous voltages do not appear at the module’s

output.

Note: Do not ground either of the input pins of the

module without grounding one of the output

pins. This may allow a non-SELV voltage to

appear between the output pins and ground.

The power module has extra-low voltage (ELV) outputs

when all inputs are ELV.

All flammable materials used in the manufacturing of

these modules are rated 94V-0, or tested to the

UL60950 A.2 for reduced thickness.

For input voltages exceeding –60 Vdc but less than or

equal to –75 Vdc, these converters have been evaluated

to the applicable requirements of BASIC INSULATION

between secondary DC MAINS DISTRIBUTION input

(classified as TNV-2 in Europe) and unearthed SELV

outputs.

The input to these units is to be provided with a

maximum 8 A time-delay fuse in the ungrounded lead.

Feature Description

Remote On/Off

Two remote on/off options are available. Positive logic turns the

module on during a logic high voltage on the ON/OFF pin, and

off during a logic low. Negative logic remote On/Off, device code

suffix “1”, turns the module off during a logic high and on during

a logic low.

Figure 10. Remote On/Off Implementation.

To turn the power module on and off, the user must supply a

switch (open collector or equivalent) to control the voltage

(Von/off) between the ON/OFF terminal and the VIN(-) terminal (see

Figure 10). Logic low is 0V ≤ Von/off ≤ 1.0V. The maximum Ion/off

during a logic low is 1mA, the switch should be maintain a logic

low level whilst sinking this current.

During a logic high, the typical maximum Von/off generated by the

module is 5V, and the maximum allowable leakage current at

Von/off = 5V is 1μA.

If not using the remote on/off feature:

For positive logic, leave the ON/OFF pin open.

For negative logic, short the ON/OFF pin to VIN(-).

Remote Sense

Remote sense minimizes the effects of distribution losses by

regulating the voltage at the remote-sense connections (See

Figure 11). The voltage between the remote-sense pins and the

output terminals must not exceed the output voltage sense

range given in the Feature Specifications table:

[VO(+) – VO(–)] – [SENSE(+) – SENSE(–)]  0.5 V

Although the output voltage can be increased by both the

remote sense and by the trim, the maximum increase for the

output voltage is not the sum of both. The maximum increase is

the larger of either the remote sense or the trim. The amount of

power delivered by the module is defined as the voltage at the

output terminals multiplied by the output current. When using

remote sense and trim, the output voltage of the module can be

increased, which at the same output current would increase the

power output of the module. Care should be taken to ensure

that the maximum output power of the module remains at or

below the maximum rated power (Maximum rated power =

Vo,set x Io,max).

Input Undervoltage Lockout

At input voltages below the input undervoltage lockout

limit, the module operation is disabled. The module will

only begin to operate once the input voltage is raised

above the undervoltage lockout turn-on threshold,

VUV/ON.

Once operating, the module will continue to operate

until the input voltage is taken below the undervoltage

turn-off threshold, VUV/OFF.

Overtemperature Protection

To provide protection under certain fault conditions, the

unit is equipped with a thermal shutdown circuit. The

unit will shutdown, if the thermal reference point (Figure

13), exceeds Tref1 = 133 OC or Tref2 = 140OC (typical), but

the thermal shutdown is not intended as a guarantee

that the unit will survive temperatures beyond its rating.

The module will automatically restart upon cool-down

to a safe temperature.

Output Overvoltage Protection

The output over voltage protection scheme of the

modules has an independent over voltage loop to

prevent single point of failure. This protection feature

latches in the event of over voltage across the output.

Cycling the on/off pin or input voltage resets the

latching protection feature. If the auto-restart option (4)

is ordered, the module will automatically restart upon

an internally programmed time elapsing.

Overcurrent Protection

To provide protection in a fault (output overload)

condition, the unit is equipped with internal

current-limiting circuitry and can endure current

limiting continuously. At the point of current-limit

inception, the unit enters hiccup mode. If the unit is

not configured with auto–restart, then it will latch off

following the over current condition. The module can be

restarted by cycling the dc input power for at least one

second or by toggling the remote on/off signal for at

least one second. If the unit is configured with the auto-

restart option (4), it will remain in the hiccup mode as

long as the overcurrent condition exists; it operates

normally, once the output current is brought back into

its specified range. The average output current during

hiccup is 10% IO, max.

Trimming allows the output voltage set point to be increased or

pin.

Connecting an external resistor (Rtrim-down) between the TRIM pin

should be ±1.0%.

The voltage between the Vo(+) and Vo(–) terminals must

not exceed the minimum output overvoltage protection

value shown in the Feature Specifications table. This

limit includes any increase in voltage due to remote-

sense compensation and output voltage set-point

adjustment trim.

Although the output voltage can be increased by both

the remote sense and by the trim, the maximum

increase for the output voltage is not the sum of both.

The maximum increase is the larger of either the remote

sense or the trim. The amount of power delivered by the

module is defined as the voltage at the output terminals

multiplied by the output current. When using remote

sense and trim, the output voltage of the module can be

increased, which at the same output current would

increase the power output of the module. Care should

be taken to ensure that the maximum output power of

the module remains at or below the maximum rated

power (Maximum rated power = VO,set x IO,max).

Thermal Considerations

The power modules operate in a variety of thermal

environments; however, sufficient cooling should be

provided to help ensure reliable operation.

Considerations include ambient temperature, airflow,

module power dissipation, and the need for increased

reliability. A reduction in the operating temperature of

the module will result in an increase in reliability. The

thermal data presented here is based on physical

measurements taken in a wind tunnel, using automated

thermo-couple instrumentation to monitor key

component temperatures: FETs, diodes, control ICs,

magnetic cores, ceramic capacitors, opto-isolators, and

module pwb conductors, while controlling the ambient

airflow rate and temperature. For a given airflow and

ambient temperature, the module output power is

increased, until one (or more) of the components

reaches its maximum derated operating temperature,

as defined in IPC-9592. This procedure is then repeated

for a different airflow or ambient temperature until a

family of module output derating curves is obtained.

Thermal Considerations (continued)

Heat-dissipating components are mounted on the top side

The thermal reference points, Tref1 and Tref2 used in the

specifications for open frame modules is shown in Figure 13.

For reliable operation Tref1 should not exceed 128oC, and Tref2

should not exceed 123oC .

Heat Transfer via Convection

Increased airflow over the module enhances the heat

transfer via convection. Derating curves showing the

maximum output current that can be delivered by the open

frame module versus local ambient temperature (TA) for natural

convection and up to 1.5m/s (300 ft./min) forced airflow are

shown in Figure 14.

detailed discussion of thermal aspects including maximum

device temperatures.

Through-Hole Soldering Information

The RoHS-compliant (Z codes) through-hole products use the

SAC (Sn/Ag/Cu) Pb-free solder and RoHS-compliant components.

The RoHS-compliant with lead solder exemption (non-Z codes)

through-hole products use Sn/Pb solder and RoHS-compliant

components. Both non-Z and Z codes are designed to be

processed through single or dual wave soldering machines. The

pins have an RoHS-compliant finish that is compatible with both

Pb and Pb-free wave soldering processes. A maximum

preheat rate of 3C/s is suggested. The wave preheat

process should be such that the temperature of the

power module board is kept below 210C. For Pb solder,

the recommended pot temperature is 260C, while the

Pb-free solder pot is 270C max. Not all RoHS-

compliant through-hole products can be processed with

paste-through-hole Pb or Pb-free reflow process. If

additional information is needed, please consult with

your GE representative for more details.

Post Solder Cleaning and Drying Considerations

Post solder cleaning is usually the final circuit-board

assembly process prior to electrical board testing. The

result of inadequate cleaning and drying can affect both

the reliability of a power module and the testability of

the finished circuit-board assembly. For guidance on

appropriate soldering, cleaning and drying procedures,

refer to GE Board Mounted Power Modules: Soldering

and Cleaning Application Note (AN04-001).
