The single output version of the XPF60-20 Series is available in three variants. The XPF60-20S has manual control only, for conventional bench-top use. The XPF60-20SA adds isolated analogue remote control plus duplicate rear terminals. The XPF60-20SP has digital remote control via USB, RS-232, and LAN (LXI) along with duplicate rear terminals. GPIB optional.

XPF60-20SA - isolated analog remote control

Some applications require analog remote control rather than digital. The XPF60- 20SA has fully galvanically isolated voltage driven remote control for both voltage and current. In addition, voltage and current front panel settings are provided as nonisolated control voltages, enabling master-slave configurations to be used.

ANALOG REMOTE INTERFACE (XPF60-20SA only)

The XPF60-20SA offers galvanically isolated analog remote control of voltage and current from control voltages. Voltage and current front panel settings generate non-isolated analog output voltages that can be used to control slave power supplies.

Input Scaling: 0 to 100% control of voltage or current from 0 to 5V or 0 to 10V (selectable)

Input Accuracy: Voltage: 0.3% +/-20mV. Current: 0.5% +/-50mA. Input impedance 10kW

Output Scaling: Set values of 0 to 100% of rated output voltage and current generate 0 to 5V (not isolated)

Output Accuracy: Voltage: 0.3% +/-;20mV. Current: 0.5% +/-50mA. Output impedance 125W

Remote On/Off: Output On/Off can be controlled by external switch closure (not isolated)
