General Description
The DRC-12V100W1AZ 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.

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.

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
No output power de-rating across the entire
input voltage range
Dismounting

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

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 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 0% to
100% of its rated current.
50% duty cycle / 5Hz to 1KHz
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.
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.
The power supply should be latch.
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.

Restriction of the usage of hazardous substances
The European directive 2011/65/EU limits the maximum impurity level of homogeneous materials such as lead,
mercury, cadmium, chrome, polybrominated flame retardants PBB and PBDE for the use in electrical and
electronic equipment. RoHS is the abbreviation for “Restriction of the use of certain hazardous substances in
electrical and electronic equipment”.
This product conforms to this standard.
PFC – Norm EN 61000-3-2
Line Current Harmonic content
Typically, the input current waveform is not sinusoidal due to the periodical peak charging of the input capacitor.
In industrial environment, complying with EN 61000-3-2 is only necessary under special conditions. Complying to
this standard can have some technical drawbacks, such as lower efficiency as well as some commercial aspects
such as higher purchasing costs. Frequently, the user does not profit from fulfilling this standard, therefore, it is
important to know whether it is mandatory to meet this standard for a specific application.

Fig. 3 Parallel Operation Connection Diagram
The power supply units (PSUs) can also be used for
parallel operation in order to increase the output power.
The difference in output voltage between the two units
must be kept to within 25mV of each other. This difference
must be verified with the same output load connected
independently to each unit.
Parameters such as EMI, inrush current, leakage current,
PARD, start up time will be different from those on the
datasheet, when two units are connected in parallel. The
user will need to verify that any differences will still allow
the two power supplies connected in parallel will work
properly in their product/application.
