Voltage/Current/Power Levels

Note: Actual maxima for voltage and current are typically 1% greater than the figures given above.
Power Range:
POWER ENVELOPE
The maximum current atany voltage settings is limited by the power envelope which is set to
give 7A at 60V rising to 20A at 20V under all ac supply conditions (both outputs loaded). At
lower output voltages the power is restricted by the 20 amps current maximum.
See PowerFlex power envelope graph on previous page.

Resolution/ Accuracy: 10mV / ± 0·1% of reading ± 2 digits
Current Meter
Resolution/ Accuracy: 10mA / ± 0·3% of reading ± 20mA
Independent Mode
In the normal mode of operation, each output is fully independent and isolated. Operation
is equivalent to two single output power supplies.
Voltage Tracking Mode
The two outputs remain isolated, but the Slave voltage controls are disabled and the Slave
voltage is set equal to the Master voltage. This can be used to generate tracking bipolar
voltages, or tracking unipolar voltages relative to different grounds.
When voltages greater than 60V are required, the outputs can be wired in series to generate
0 to 120V with the voltage controlled from the Master.
When currents greater than 20A are required, the outputs can be wired in parallel to create
the equivalent of a 40A power supply with the voltage controlled from the Master.

Forward protection by Over-voltage Protection (OVP) trip.
Reverse protection by diode clamp for currents to 3A.
Output trips off for over-temperature.
Operations that could cause an unexpected change in voltage or
current settings are interlocked with the output switch.
Universal 4mm safety binding posts on 19mm (0·75”) spacing at front.
Screw terminals at rear (CPX400DP only).
Voltage sensing is selected as Local or Remote by front panel switch.
Sprung loaded screw-less terminals at front.

Each output has an independent DC On/Off control, however, an additional control button is
provided which turn both outputs on or off simultaneously.
The CPX400DP offers full remote control and read-back using RS-232, USB, GPIB or LAN
(compliant with LXI class C). All interfaces are at ground potential and opto-isolated from the
output terminals. Note: Remote/Local Sense, is manually selectable only.
RS-232
