TECHNICAL DATASHEET
CliQ M DIN Rail Power Supply
24V 81.6W 1 Phase / DRM-24V80W1PN
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 Overload (OLP) and Overcurrent (OCP)
Protections will be activated when output current is > 150% of IO
(output current). Upon such an occurrence, VO (output voltage)
will start to droop, refer to Ⓒ and after 7 sec output current will
limit to 4.6A typ., refer to Ⓐ). Once VO is below 11Vdc typ., the
power supply will operate in “Hiccup mode”. The power supply
will recover once the fault condition due to OLP or OCP is
removed, then IO is back within the specified range.
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
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 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.
