Front Panel Connections

Load Input
The INPUT terminals for the load circuit on the front panel accept 4mm plugs into the end, 4mm
diameter wire or plugs into the cross hole, or ¼ inch spade connections (with a maximum blade
width of ½ inch). Their maximum current rating is 30 Amps. For higher currents (or lower circuit
resistance) use the rear panel terminals; do not use both simultaneously.
The load circuit is isolated from ground, and potentials up to ± 300 Volts to ground are allowed,
but it is essential to observe safe insulation practice.
Ensure that the source is connected with the correct polarity.
The maximum current through these terminals is 30 Amps.
The maximum voltage allowed across the load is 80 Volts.
The unit does not have a fuse in the load circuit: ensure that the maximum
prospective fault current is limited to a safe level.
Current Monitor Output
The Current Monitor terminals provide a voltage proportional to the load current flowing with a
scaling factor of 50 mV per Amp (4 Volts for 80 Amps full scale). The output impedance is 600Ω
and the calibration assumes a high impedance load.
A differential driver allows a common mode range of ± 3 Volts between the negative
monitor terminal and the negative load terminal. The output will be inaccurate (and the
unit may be damaged) if voltages exceeding this are applied.

Rear Panel Connections

Load Input
The INPUT terminals for the load circuit on the rear panel accept 4mm plugs into the end (4mm
plugs will only support 32 Amps), 6mm diameter wire or plugs into the cross hole or 8mm spade
connections (with a maximum blade width of 16mm).
The wiring and connection arrangement must be capable of supporting the current required; for
80 Amps, 16mm
The load circuit is isolated from ground, and potentials up to ± 300 Volts to ground are allowed,
but it is essential to observe safe insulation practice.
Ensure that the source is connected with the correct polarity.
The maximum current through these terminals is 80 Amps.
The maximum voltage allowed across the load is 80 Volts.
The unit does not have a fuse in the load circuit: ensure that the maximum
prospective fault current is limited to a safe level.
Terminal Blocks
All other rear panel connections are made via the screw-less terminal blocks. To make
connections to the terminal blocks, use a flat screwdriver to press the spring-loaded orange
actuator inwards to open the wire clamp; insert the wire end fully into the hole and release the
actuator. Ensure the wire is properly gripped. Take care to observe the marked polarity.
Current Monitor Output
The top pair of terminals, marked CURRENT MONITOR, provide the current monitor output.
They are wired in parallel with the front panel sockets (see above).
