General Description
The DRC-12V30W1AZ 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.

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.
If the output capacity is not reduced when the
surrounding air temperature >55°C, the
device may run into Over Temperature
Protection. When activated, the output
voltage will go into latch-off mode and
recoverable by AC power recycle.
In order for the device to function in the
manner intended, it is also necessary to keep
a safety distance of 25mm with adjacent units
while the device is in operation.
Depending
on
the
surrounding
air
temperature and output load delivered by the
power supply, the device can be very hot!
If the device has to be mounted in any other
orientation, please do not hesitate to contact
[email protected] for more details.

Assembly & Installation
The power supply unit (PSU) can be mounted on 35mm DIN rails in accordance with EN60715. The device should be installed with
input terminal block at the bottom.
Each device is delivered ready to install.
Mounting
Dismounting

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.

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

–
–
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 above and below the device as well as a lateral distance of
25mm 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.
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 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 set value.
Hold-up Time
Hold up time is the time when the AC input collapses and output voltage retains regulation for a certain period of time. The time
required for the output to reach 90% of its set value, after the input voltage is removed.

Inrush Current
Overload & Overcurrent Protections
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.
The power supply’s Overload (OLP) and Over current (OCP)
Protections will be activated when output current is >130% of IO
(Max load). In such occurrence, the VO will start to droop and
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.
It is not recommended to prolong the duration of IO when it is
<130% but >100%, since it may cause damage to the PSU.
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.
Over Temperature Protection
As mentioned above, the power supply also has Over
Temperature Protection (OTP). In the event of a higher operating
temperature at 100% load, the power supply will run into OTP
when the operating temperature is beyond what is recommended
in the de-rating graph. When activated, the output voltage will go
into latch-off mode until the component temperature cools down
and the AC power is recycled.
Short Circuit Protection
Overvoltage Protection
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.
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”.
