Over-Current Protection

Over-Current Protection (OCP) can be set from 0·01A to 5·5A. If the output current exceeds the set OCP the output is shut down (typically within 35ms).

To set OCP press SHIFT, OCP; the 10mA step JOG indicator will start flashing and the jog rotary control can be used to increment/decrement the OCP setting in 10mA steps. Press OK to confirm the new setting; to exit without entering a new value press ESCAPE. The factory default setting is 5·50A.

If the OCP is tripped the display shows the message OCP triP and the output is turned off. Pressing ESCAPE at this point removes the message and the display now shows the preset voltage and current limit. When the cause of the OCP has been removed (or the OCP limit changed) the output can be turned on again.

Note that as with OVP, the OCP setting is not changed when the range is changed.

Note also that is possible and valid to set OCP below the set current limit. For example, the power supply may be used to repetitively test a unit under test (UUT) which normally takes a peak current of, say, 2 Amps. However, a faulty UUT would take a current of more than 2 Amps and would be damaged by being left in a 2 Amp current-limited state. In this case the current limit could be set to 2·1A, say, and the OCP set to 2·0A to ensure that a faulty UUT will trip the supply off.

Output Protection

In addition to OVP and OCP for forward over-voltage and over-current protection, the output is protected from reverse voltages by a diode; the continuous reverse current must not exceed 3 Amps although transients can be much higher.

Output Power (V x A)

If SHIFT, V x A is pressed the voltage display shows the product of measured output voltage x measured current and the current display shows UA. V x A is a momentary function, i.e. it gives an instantaneous, not a continuous, reading of the output power; the reading is held whilst the key is pressed. Pressing V x A cancels SHIFT. Jog is temporarily disabled (and the JOG indicators are turned off) during the V x A display.

Temperature Trip

If the safe internal temperature limit is exceeded because, for example, the fan vents have been blocked, the output is turned off and the display will show OtP triP. Pressing ESCAPE at this point will do one of two things:

i.If the over-temperature condition has already cleared the message will be removed and the display will show preset voltage and current limit. Assuming the cause of the over-temperature has been rectified the output can be turned on again.

ii.If the instrument is still above the safe temperature limit the OtP triP message will flash slowly ('lazy' flash) until the instrument has cooled, at which point the display will show preset voltage and current limit again. Assuming the cause of the over-temperature has been rectified the output can be turned on again.

Alarm Output

The recessed 2-pin connector on the rear panel is directly connected to an opto-coupled NPN switching transistor (pin 1 emitter, pin 2 collector) which is turned on (i.e. switch 'closure') according to the conditions specified in the Extra Functions section, see later. The default condition is switch closure for any trip condition (OVP, OCP, SENSE or OTP). The maximum open-circuit voltage permitted across the switch is 30VDC and the nominal sink current for switch closure is 1mA.
