Low-cost/watt DC power supplies provide 320-W output

The models 9103 and 9104 multi-range DC power supplies operate in constant voltage (CV) or constant current (CC) mode and deliver up to 320 W in any combination of its rated voltage and current: 42 V/20 A (model 9103) and 84 V/10 A (model 9104). These models can replace multiple power supplies on a bench, making them suitable for use in electronics manufacturing, engineering, service and repair, and education.

Multi-range power supplies provide greater flexibility than conventional power supplies by extending the operating range beyond a single maximum power point. The supplies can provide any combination of higher voltage or higher current along a maximum power curve.

The front panel provides a dual four-digit LED display, on/off control, and simple keypad and rotary control knobs for voltage and current. The front panel triple binding post output terminal connects to double banana plugs or wires. The power supplies also feature three user-defined voltage and current presets. Configurable square, triangular, or trapezoidal waveforms are available in transient operation mode.

The rear analog remote control terminal sets the output voltage and current or remotely enables or disables the output. Additionally, models 9103 and 9104 provide a remote sense terminal for voltage drop compensation across output leads. Users can connect to the standard USB interface for remote PC connectivity with the included software. Both models offer adjustable voltage and current limits, built-in overvoltage protection, overtemperature protection, overload protection, and key lock function.
