Application Notes

Peak Loading

The peak loading and overload characteristics can be programmed into one of two modes by

appropriate selection of the OCP mode switch on the front panel.

OCP Mode switch set to position 1

A peak load of up-to 150% can be taken for a given duration. This duration depends on the

percentage of peak load taken and can be determined by graph A below.

T-peak

I-peak

If the load is reduced to less than 100% of nominal either before or at the end of the duration,

then there is a period of recovery needed to allow the power supply to cool down before the

peak load can be re-applied. The time required for recovery depends on the amount of reduction

of load and can be determined by graph B below.

I-recovery

T-recovery

However, if the peak load period exceeds the duration indicated by graph A the output will go

into constant current mode for protection. The constant current value will be 105% of the

nominal rating.

During constant current operation, if the output voltage should fall below 40% of the rated

voltage then the output will turn off and try to restart for five times before turning off

permanently. Once this has happened, the output will need to be reset by turning the AC mains

off and on again.

A peak load of up-to 150% can be taken for a given duration. This duration depends on the

percentage of peak load taken as described by graph A.

OCP Mode switch set to position 2

Once the peak load duration is exceeded, the output will turn off for 3-4 seconds before

automatically restarting.

Remote Control

The output can be controlled by applying a voltage between

pin 3 of the DC output with respect to pin 4. The effect of the

control is dependant upon the RC switch setting on the front

panel.

If the switch is set to position 1 then the output can be

disabled by applying a suitable voltage.

<0.8 V or Open Circuit

>2.5 V, <9.0 V

If the switch is set to position 2 then the output can be

enabled by applying a voltage. In the range of 2.5 V to 9.0 V

limited to 20 mA.
