Description
The MW010A, B, C, BK, and CL Power Modules are
dc-dc converters that operate over an input voltage
range of 36þVdc to 75þVdc and provide precisely
regulated dc outputs. The outputs are fully isolated
from the inputs, allowing versatile polarity configura-
tions and grounding connections. The modules have
maximum power ratings of 10 W at a typical full-load
efficiency of 83% (80% for the MW010A).
The modules are encapsulated in nonconductive
cases that mount on PC boards. In a natural convec-
tion environment, the modules are rated to full load at
85 °C with no heat sinking or external filtering.
For applications requiring remote on/off, the
MW010A1, B1, C1, BK1, and CL1 Power Modules
are available. These modules are equivalent to the
previously described modules, except for the addition
of the remote on/off and associated terminal.

Absolute Maximum Ratings
Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are abso-
lute stress ratings only. Functional operation of the device is not implied at these or any other conditions in excess
of those given in the operations sections of the data sheet. Exposure to absolute maximum ratings for extended
periods can adversely affect device reliability.

Fusing Considerations
CAUTION: This power module is not internally fused. An input line fuse must always be used.
This encapsulated power module can be used in a wide variety of applications, ranging from simple stand-alone
operation to an integrated part of a sophisticated power architecture. To preserve maximum flexibility, internal fus-
ing is not included; however, to achieve maximum safety and system protection, always use an input line fuse. The
safety agencies require a normal-blow, dc fuse with a maximum rating of 5 A in series with the ungrounded input
lead (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 manufac-
turer’s data for further information.

be made using a BNC socket. Position the load between
50.8 mm (2 in.) and 76.2 mm (3 in.) from the module.

Feature Descriptions
Output Overvoltage Clamp
The output overvoltage clamp consists of control cir-
cuitry, independent of the primary regulation loop, that
monitors the voltage on the output terminals. The con-
trol loop of the clamp has a set point that is higher than
the set point of the primary loop (see Feature Specifi-
cations table). This provides a redundant voltage-con-
trol that reduces the risk of output overvoltage.
Current Limit
To provide protection in a fault (output overload) condi-
tion, the unit is equipped with internal current-limiting
and can endure current limiting for an unlimited dura-
tion. At the point of current-limit inception, the unit
shifts from voltage control to current control. If the out-
put voltage is pulled very low during a severe fault, the
current-limit circuit can exhibit either foldback or tailout
characteristics (output-current decrease or increase).
The unit operates normally once the output current is
brought back into its specified range.
Optional Remote On/Off
The remote on/off option can be ordered using a code
suffix of “1” (see Ordering Information section). To turn
the power module on and off, the user must supply a
switch to control the voltage between the on/off termi-
nal and the VI(–) terminal (Von/off). The s witch can be an
open collector or equivalent (see Figure 3). A logic low
is V on/off = 0 V to 1.2 V, during which the module is on.
The maximum Ion/off during a logic low is 1 mA. The
s witch should maintain a logic low v oltage while sinking
1 mA.
During a logic high, the maximum Von/off generated by
the power module is 18 V. The maximum allowable
leakage current of the switch at Von/off = 18 V is 50 µA.
Note: A PWB trace between the on/off terminal and
the VI(–) terminal can be used to override the
remote on/off.
CAUTION: To avoid damaging the module or
external circuitry, the VI(–) pin must be
connected to the –48 V source before
or simultaneously to connecting the
on/off pin to the –48 V source (either
directly or through the external on/off
circuitry).
Either the user-supplied switch or the override jumper
should be wired into the circuit via individual traces not
common with the VI(–) po wer current path. Connect the
switch or jumper at the power module terminals (see
Figure 23). Configuring the switch connection in this
way prevents noise from falsely triggering the remote
on/off.

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-1950, CSA 22.2-950, EN60950.
For the converter output to be considered meeting the
requirements for safety extra-low voltage (SELV), one
of the following must be true:
nAll inputs are SELV and floating, with all outputs also
floating.
nAll inputs are SELV and grounded, with all outputs
also grounded.
nAny non-SELV input must be provided with rein-
forced insulation from any other hazardous voltages,
including the ac mains, and must have an SELV reli-
ability test performed on it in combination with the
converters. Inputs must meet SELV requirement.
If the input meets extra-low voltage (ELV) require-
ments, then the converter’s output is considered ELV.
The input to these units is to be provided with a maxi-
mum 5 A normal-blow fuse in the ungrounded lead.
Design Considerations
Input Filtering
An internal aluminum electrolytic capacitor is used for
filtering; therefore, input ripple increases as tempera-
ture decreases. (There is approximately two times
more ripple at 0 °C than at 25 °C and eight times more
ripple at –40 °C than at 25 °C.) The power module
functions properly down to –40þ°C with no additional
filtering. If needed, an external capacitor across the
input with an impedance of 0.3 ¾ at 100þkHz over the
desired temperature range can be added to limit the
input ripple current to the typical level given in the Input
Specifications table.
Output Voltage Reversal
CAUTION: Applying a reverse voltage across the
module output forward biases an inter-
nal diode. Attempting to start the mod-
ule under this condition can damage
the module.
