Output Current
Setting:
Output Mode:
By single logarithmic control.
The power supply operates in constant current or constant
voltage modes with automatic cross-over. Decimal points
flash to indicate constant current mode.
Isolated, True parallel, Series or Series Tracking via front
panel switches.
Configuration
Selection:
(QMD and QMT only)
Output Switch:
Isolates the output and permits voltage and current limits to
be set up before connecting the load.
4mm terminals on 19mm (0.75") spacing.
Constant Voltage: Typically <5m
