General specifications apply for the temperature range 5°C to 40°C. Accuracy specifications
apply for the temperature range 18°C to 28°C after 1 hour warm-up with no load and calibration
at 23°C. Typical specifications are determined by design and are not guaranteed.

By coarse and fine controls.
By single logarithmic control.
Constant voltage or constant current with automatic cross-over provided
that the power demanded stays within the power envelope, see graph.
Outside of this envelope the output becomes unregulated.
Electronic. Preset voltage and current displayed when off.
Universal 4mm safety binding posts on 19mm (0·75") pitch. 30A max.
Switchable between local and remote. Spring-loaded push terminals for
remote connection.
Forward protection by Over-Voltage Protection (OVP) trip; maximum
voltage that should be applied to the terminals is 70V.
Reverse protection by diode clamp for reverse currents up to 3A.
The output will be tripped off if a fault causes the internal temperature to
rise excessively.
10% to 110% of maximum output voltage set by front panel screwdriver
adjustment.
Change in output for a 10% line change:
Constant voltage: <0.01% of maximum output
Constant current: <0.01% of maximum output
Change in output for any load change within PowerFlex envelope,
remote sense connected:
Constant voltage: <0.01% of maximum output
Constant current: <0.05% of maximum output
4mVrms max; typically <2mVrms, <10mV pk-pk, at maximum load, CV
mode.
