General Description

The DRC-12V60W1A☐ is part of the Chrome DIN Rail Power Supply series, which is designed for use in compact cabinets for home

automations and the food and beverage industry. Delta’s Chrome DIN Rail Power Supply series offers double isolated input. This means

that no Earth connection is required thus resulting in low leakage current. This product provides a universal input voltage range of 90-

264Vac, and a wide temperature range of -25°C to 71°C. The Chrome series is certified to safety standard according to IEC/EN/UL

60950-1 Information Technology Equipment (ITE) and UL 508 Industrial Control Equipment (ICE). The series is also fully compliant with

RoHS Directive 2011/65/EU for environmental protection. NEC Class 2 and Limited Power Source (LPS) approvals are available for this

product.

Engineering Data

Output Load De-rating VS Surrounding Air Temperature

Note

1. Power supply components may degrade, or

be damaged, when the power supply is

continuously used outside the shaded region,

refer to the graph shown in Fig. 1.

2. If the output capacity is not reduced when the

surrounding air temperature exceeds its

specification as defined on Page 3 under

“Environment”, the device may run into Over

Temperature Protection. When activated, the

output voltage will go into latch mode and

recover when AC power recycles.

3. In order for the device to function in the

manner intended, it is also necessary to keep

a safety distance as recommended in the

safety instructions while the device is in

operation.

4. Depending on the surrounding air temperature

and output load delivered by the power

supply, the device can be very hot!

5. If the device has to be mounted in any other

orientation, please contact

info@deltapsu.com for more details.

Output Load De-rating VS Input Voltage

Assembly & Installation

The power supply unit (PSU) can be mounted on 35mm DIN rails in accordance with EN 60715. The device should be installed with input

terminal block at the bottom.

Each device is delivered ready to install.

Mounting

 No output power de-rating across the entire

input voltage range

Dismounting

Fig. 2.1 Mounting

Snap on the DIN rail as shown in Fig. 2.1:

1. Tilt the unit upwards and insert it onto the DIN rail.

2. Push downwards until stopped.

3. Press against the bottom front side for locking.

4. Shake the unit slightly to ensure that it is secured.

Fig. 2.2 Dismounting

To uninstall, pull or slide down the latch with screw driver as

shown in Fig. 2.2. Then slide the power supply unit (PSU) in

the opposite direction, release the latch and pull out the power

supply unit (PSU) from the rail.

Safety Instructions

Functions

 Graph illustrating the Start-up Time, Rise Time, and Hold-up Time

Start-up Time

The time required for the output voltage to reach 90% of its final steady state set value, after the input voltage is applied.

Rise Time

The time required for the output voltage to change from 10% to 90% of its final steady state set value.

Hold-up Time

Time between the collapse of the AC input voltage, and the output falling to 95% of its steady state set value.

• ALWAYS switch mains of input power OFF before connecting and

disconnecting the input voltage to the unit. If mains are not turned

OFF, there is risk of explosion / severe damage.

• To guarantee sufficient convection cooling, keep a distance of

50mm (1.96 inch) above and below the device as well as a

lateral distance of 25mm (0.98 inch) to other units.

• Note that the enclosure of the device can become very hot

depending on the surrounding air temperature and load of the

power supply. Risk of burns!

• DO NOT insert any objects into the unit.

• Hazardous voltages may be present for up to 5 minutes after the

input mains voltage is disconnected. Do not touch the unit during

this time.

• The power supplies unit should be installed in minimum IP54 rated

enclosure.

• The power supplies are built in units and must be installed in a

cabinet or room (condensation free environment and indoor

location) that is relatively free of conductive contaminants.

Inrush Current

Inrush current is the peak, instantaneous, input current measured

and, occurs when the input voltage is first applied. For AC input

voltages, the maximum peak value of inrush current will occur

during the first half cycle of the applied AC voltage. This peak value

decreases exponentially during subsequent cycles of AC voltage.

Dynamic Response

The power supply output voltage will remains within ±5% of its

steady state value, when subjected to a dynamic load from 10% to

100% of its rated current.

 50% duty cycle / 5Hz to 1kHz

Overvoltage Protection (Latch Mode)

The power supply’s overvoltage circuit will be activated when its

internal feedback circuit fails. The output voltage shall not exceed

its specifications defined on Page 3 under “Protections”. Power

supply will latch, and require removal/re-application of input AC

voltage in order to restart.

Overload & Overcurrent Protections (Auto-Recovery)

The power supply’s Overload (OLP) and Over current (OCP)

Protections will be activated when output current exceeds its

specification as defined on Page 3 under “Protections”. In such

occurrence, once the power supply has reached its maximum

power limit, the protection is activated and the power supply will go

into “Hiccup mode” (Auto-Recovery). The power supply will recover

once the fault condition of the OLP and OCP is removed and IO is

back within the specifications.

Over Temperature Protection (Latch Mode)

As described in load de-rating section, the power supply also has

Over Temperature Protection (OTP). In the event of a higher

operating temperature at 100% load; or, when the operating

temperature is beyond what is recommended in the de-rating

graph, the OTP circuit will be activated. When activated, power

supply will latch, until the surrounding air temperature drops to its

normal operating temperature or the load is reduced as

recommended in the de-rating graph. Removal/re-application of

input AC voltage will then be required in order to restart.

Short Circuit Protection (Auto-Recovery)

The power supply’s output OLP/OCP function also provides

protection against short circuits. When a short circuit is applied, the

output current will operate in “Hiccup mode”, as shown in the

illustration in the OLP/OCP section on this page. The power supply

will return to normal operation after the short circuit is removed.

External Input Protection Device

The unit is protected with internal fuse (not replaceable) at L pin

and it has been tested and approved on 20A (UL) and 16A (IEC)

branch circuits without additional protection device. An external

protection device is only required if the supplying branch has an

ampacity greater than above. Thus, if an external protective device

is necessary, or, utilized, a minimum value of 16A B- or 8A C-

characteristic breaker should be used.
