5.7 OCL – Analog Programming Over Current Limit
Analog Programming Over Current Limit (OCL) function provides the ability to limit analog
programming of maximum current programming value. Setting OCL to ON state clamps maximum
current programming value to digital programming value (set by Front Panel or communication).
Setting OCL to OFF state (default configuration) provides the ability to program current setting
according to power supply rated current value (up to about 108% of rated current).

OCL Example (10 Volts, 500 Amperes supply)

VOLT 10
CURR 300
SYST:RANG 10
CURR:EXT:MODE VOL
Set external voltage to 4V
CURR:EXT:LIM ON
Set external voltage to 8V
Operation 2 sets digital current setting to 300 Amperes. Following operation 5, current setting is
200 Amperes. Following operation 6, OCL function is enabled, limiting current programming value
to 300 Amperes (output current setting is not affected). Following operation 7, current setting is 300
Amperes (OCL function limits current setting to digital setting).
Enable analog programming by rear panel J1 pin 6, short to J1 pin 11.
