B&K Precision debuts low-cost-per-watt multi-range DC supplies
Yorba Linda, CA. B&K Precision has announced its latest multi-range DC power supplies, models 9103 and 9104. These new power supplies operate in constant-voltage (CV) or constant-current (CC) mode and can deliver up to 320 W in any combination of rated voltage and current—42 V/20 A (Model 9103) and 84 V/10 A (Model 9104). With a lightweight, compact form factor, these models can replace multiple power supplies on a bench, making them suitable for a variety of uses in electronics manufacturing, engineering, service and repair, and education.
Multi-range power supplies provide users 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 9103 and 9104’s cost-effective design not only saves bench space but also eliminates purchasing unnecessary power.
The front panel provides a bright, dual 4-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 for quick recall. 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 enable or disable 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 (OVP), overtemperature protection (OTP), overload protection (OLP), and key lock function.
Available immediately, B&K Precision’s 9103 and 9104 multi-range power supplies are backed by a 2-year warranty and listed at $495 each.
