TECHNICAL DATASHEET
CliQ M DIN Rail Power Supply
24V 120W 1 Phase / DRM-24V120W1PN
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.
Overload & Overcurrent Protections (Auto-Recovery)
The power supply’s Overcurrent Protection (OCP) will be
activated when output current is > 8A typ. In such occurrence, the
VO will start to droop (refer to Ⓒ and output current will limit to
6.5A typ. after 7sec, refer to Ⓐ) and once the output voltage is
below 11Vdc 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.
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.
Short Circuit Protection (Auto-Recovery)
The power supply’s output Short Circuit Protection function also
provides protection against short circuits. When a short circuit is
applied, the output current will operate in “Hiccup mode”. The
power supply will return to normal operation after the short circuit
is removed.
Overvoltage Protection (Auto-Recovery)
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 6 under “Protections”.
Over Temperature Protection (Auto-Recovery)
As described in load de-rating section, the power supply also has
Over Temperature Protection (OTP). In the event of a hi gher
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.
