The Xantrex XFR 60-46 is a 2.76 kW programmable DC power supply tailored for research, production testing, and OEM environments. It delivers clean, reliable power with zero-voltage “soft-switching” technology to minimize switching transients and maximize efficiency. Housed in a full 19-inch, 2U rack-mount chassis, the unit’s thermal design allows back-to-back stacking without additional ventilation clearance.

Key Features

Output Voltage Range: 0 – 60 V
Output Current Range: 0 – 46 A
Maximum Power: 2,760 W
Zero-Voltage Soft-Switching for high efficiency and reduced heat
Simultaneous LED display of voltage and current on front panel
Constant Voltage (CV) and Constant Current (CC) operating modes
Standby mode for remote on/off control
Over-Voltage Protection (OVP) and Over-Temperature Protection (OTP)

Front Panel Controls

The front panel features two high-contrast LED displays for real-time voltage and current readouts. Rotary knobs provide fine and coarse adjustments of setpoints, while an illuminated standby pushbutton enables remote activation. Mode and status LEDs indicate CV/CC operation, standby state, and fault conditions for intuitive local control.

Rear Panel Connectors and Switches

AC Input: IEC C14 inlet with integrated power switch and fuse
Output Terminals: Heavy-duty binding posts for secure high-current connections
J2 Connector: 15-pin D-sub interface for analog remote programming and monitoring
SW1 DIP Switch: Configures local/remote control modes and safety interlocks
