OUTPUT SPECIFICATIONS

Voltage Range: 0V to 35V

Current Range: 0A to 10A

Power Range: Up to 175W

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.

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 Impedance:

Typically <5mΩ in constant voltage mode.
Typically >5kΩ in constant current mode (voltage limit at max).

Output Protection: Forward protection by Over-Voltage Protection (OVP) trip; maximum

voltage that should be applied to the terminals is 50V.

Reverse protection by diode clamp for reverse currents up to 3A.
