Output Specifications

Specification

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.

Voltage Range:

0V to 60V

Current Range:

0A to 20A

Power Range:

Up to 420W

Output Voltage Setting:

By coarse and fine controls.

Output Current Setting:

By single logarithmic control.

Operating Mode:

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.

XPF 60-20

POWER ENVELOPE

Output Switch:	Electronic. Preset voltage and current displayed when off.
Output Terminals:	4mm terminals on 19mm (0·75”) pitch. 30A max.
Sensing:	Switchable between local and remote. Spring-loaded push terminals
	for remote connection.
Output Protection:	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.
Over-temperature Protection:	The output will be tripped off if a fault causes the internal
	temperature to rise excessively.
OVP Range:	10% to 110% of maximum output voltage set by front panel
	screwdriver adjustment.
Line Regulation:	Change in output for a 10% line change:
	Constant voltage: <0.01% of maximum output
	Constant current: <0.01% of maximum output
Load Regulation:	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
Ripple & Noise	4mVrms max; typically <2mVrms, <10mV pk-pk, at maximum load,
(20MHz bandwidth):	CV mode.
