TECHNICAL DATASHEET
Sync DIN Rail Power Supply
5V 50W Series / DRS-5V50W1Aâ¡ / DRS-5V50W1Nâ¡
Overload & Overcurrent Protections (Auto-Recovery)
The power supplyâs Overload (OLP) and Overcurrent (OCP)
Protections will be activated when output current is about 6.0A
typ. for DRS-5V50W1Nâ and 6.7A typ. for DRS-5V50W1Aâ.
When this occurs, the VO will start to droop (refer to ⶠbelow).
Once the output voltage is below about 1.4Vdc typ., the power
supply will start to operate in âHiccup modeâ (Auto-Recovery
mode). The power supply will recover once the fault condition of
the OCP is removed and output current is back within the
specifications.
Overvoltage Protection (Latch Mode)
The power supplyâs overvoltage circuit will be activated when its
internal feedback circuit fails. The output voltage shall not exceed
its specifications defined on Page 3 under âProtectionsâ. 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 supplyâs output Short Circuit Protection function also
provides protection against short circuits. When a short circuit is
applied, the output current will operate in âHiccup modeâ. 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.
Delta RoHS Compliant
Restriction of the usage of hazardous substances
The European directive 2011/65/EU limits the maximum impurity level of homogeneous materials such as lead,
mercury, cadmium, chrome, polybrominated flame retardants PBB and PBDE for the use in electrical and
electronic equipment. RoHS is the abbreviation for âRestriction of the use of certain hazardous substances in
electrical and electronic equipmentâ.
This product conforms to this standard.
