Peak Loading
OCP Mode switch set to position 1
I
T-peak
AC-DC Power Supplies
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.
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.
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.
T
I-peak
I-recovery
T-recovery
0
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.
OCP Mode switch set to position 2
I
T-peak
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.
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.
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.
