Overload & Overcurrent Protections

The power supply’s Overload (OLP) and Overcurrent (OCP)

Protections will be activated when output current exceeds

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

PSU.

Short Circuit Protection

The power supply’s output OLP/OCP function also provides

protection against short circuits. When a short circuit is applied,

the output current will operate in “Hiccup mode”, as shown in

the illustration in the OLP/OCP section on this page. The

power supply will return to normal operation after the short

circuit is removed.

Overvoltage Protection

The power supply’s overvoltage circuit will be activated when

its internal feedback circuit fails. The output voltage shall not

exceed

its

specifications

under

“Protections”.

Over Temperature Protection

As mentioned above, the power supply also has Over

Temperature Protection (OTP). In the event of a higher

operating temperature at 100% load, the power supply will run

into OTP when the operating temperature is beyond what is

recommended in the de-rating graph. When activated, the

output voltage will go into bouncing mode until the temperature

drops to its normal operating temperature as recommended in

the de-rating graph.

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 “Restriction of the use of certain hazardous substances in

electrical and electronic equipment”.

This product conforms to this standard.
