TECHNICAL DATASHEET
LYTE DIN Rail Power Supply
24V 120W 1 Phase / DRL-24V120W1A□
Overload & Overcurrent Protections (Continuous Current)
The power supply’s Overload (OLP) and Overcurrent (OCP)
Protections will be activated when output current is 105~150% of
IO (Max load). Upon such an occurrence, the VO (output voltage)
will start to droop. Once the power supply has reached its
maximum power limit, the protection will be activated; and, the
power supply will operate in continuous current. The power
supply will recover once the cause of OLP or OCP is removed,
and IO (output current) is back within the specified range.
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 as described in “Protections” section. Power
supply will latch off, and require removal/re-application of input
AC voltage in order to restart.
The power supply should be latch.
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.
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.
