Overload & Overcurrent Protections

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

Protections will be activated when output current (I1) exceeds

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

<110-150% but >100%, since it may cause damage to the PSU.

Overvoltage Protection

The power supply’s overvoltage circuit will be activated when its

internal feedback circuit fails. The output voltage (V1) shall not

exceed its specifications defined on Page 3 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.

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.

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.

PFC – Norm EN 61000-3-2

Line Current Harmonic content

Typically, the input current waveform is not sinusodial due to the periodical peak charging of the input capacitor.

In industrial environment, complying with EN 61000-3-2 is only necessary under special conditions. Complying

to this standard can have some technical drawbacks, such as lower efficiency as well as some commercial

aspects such as higher purchasing costs. Frequently, the user does not profit from fulfilling this standard,

therefore, it is important to know whether it is mandatory to meet this standard for a specific application.
