TECHNICAL DATASHEET
Chrome DIN Rail Power Supply
24V 91.2W 1 Phase (Class II & NEC Class 2) / DRC-24V100W1A□
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 Over current (OCP)
Protections will be activated when output current is 3.8A IO (Max
load) < 5.7A. In such occurrence, the VO will start to droop and
once the output voltage is below 13Vdc typ., 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.
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.
Additionally, if the IO is >102~108% for a prolong period of time
(depending on the load), the Over Temperature Protection (OTP)
will be activated due to high temperature on critical components.
The power supply will then go into “Latch mode” until the PSU
cools down and the AC power is recycled.
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 off, 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.
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 off, and require removal/re-application of input
AC voltage in order to restart.
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.
The power supply should be latch.
