TECHNICAL DATASHEET
CliQ II DIN Rail Power Supply
24V 91.2W 1 Phase, NEC Class 2 / DRP-24V100W1NN
Overload & Overcurrent Protections
Overvoltage Protection
The power supply’s Overcurrent (OCP) Protection will be
activated when output current is 3.8A I_O (Max load) < 8A. In such
occurrence, the V_O will start to droop and once the output voltage
is below 12.5Vdc typ., the power supply will go into “Hiccup mode”
(Auto-Recovery). The power supply will recover once the fault
condition of the OCP is removed and I_O is back within the
specifications.
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”.
The Overload Protection (OLP) is limited at output power of less
than 100W according to safety requirements.
Short Circuit 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.
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 bouncing mode until the temperature drops to its normal
operating temperature as recommended in the de-rating graph.
