TECHNICAL DATASHEET
Sync DIN Rail Power Supply
24V 30W 1 Phase (NEC Class 2) / DRS-24V30W1NZ
Overload & Overcurrent Protections (Auto-Recovery)
The power supply’s Overload (OLP) and Overcurrent (OCP)
Protections will be activated when output current is 105~160% of
IO (Max load). In such occurrence, the VO will start to droop and
once the power supply has reached its maximum power limit, the
protection is activated and 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.
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.
The power supply should be latch.
It is not recommended to prolong the duration of IO when it is
<105-160% but > 100%, since it may cause damage to the PSU.
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.
