QPX750 Instruction Manual
V CONTROL and I CONTROL are 0…5V or 0…10V inputs with respect to COM terminal that provide
quasi-analogue control of the Output Voltage and Current Control, respectively.
The output terminal voltage and output current may be monitored on V MONITOR and I MONITOR,
respectively. V MONITOR and I MONITOR are always available at the rear.
CAUTION
V and I CONTROL inputs are differential, with a limited common mode range of ± 2.5Vdc
with respect to the negative output. They should be driven from a ‘floating’ source such
as another power supply.
MONITOR outputs are differential with a limited common mode range of ± 2.5Vdc with
respect to the negative output. They should be connected to a measuring system with
‘floating’ inputs such as a DMM.
Do not apply volts greater than 20VDC to ANALOG CONTROL terminals, with respect to
COM.
Output Remote Sense: -S, +S See 'Remote Sense Terminals’ for more details.
WARNING
ANALOG CONTROL /MONITOR and SENSE terminals are referenced to the output
negative Output terminal. Voltages above 60VDC are hazardous live according to EN
61010-1 and great care must be taken when using the power supply at voltages above
this level.
Always make connections to the instrument with the OUTPUT off.

Output Terminals
Refer to Output Terminals on front panel.
NOTE
The M4 threaded screw marked provides a connection point to safety earth ground.
A M4 Ring tab must be used, with an appropriate washer
