LYTE II DIN Rail Power Supply
DRL-480W series / DRL-V480W1EN
Overload & Overcurrent Protections (Continuous Current)
The power supply offers constant current limit protection for
inductive and capacitive load applications when output current
range is 105~150% of I (Max load) and output voltage large than
O
80%. Upon such an occurrence, the V
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 I
back within the specified range.
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.
All parameters are specified at 25°C ambient and AC input unless otherwise indicated.

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.
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.
