Circuit Specialists 120 Volt, 3.0 Amp DC Power Supply

The CSI12003X is a fully regulated benchtop linear power supply with adjustable current limiting.

The CSI12003X is a regulated linear bench power supply with adjustable current limiting. The large, clear LED display shows both volts and amps. The maximum current output can be preset by the user via a front panel screwdriver adjustment screw while the voltage is adjustable by a large front panel multi-turn knob for precise voltage settings. Output is by front panel banana jacks and there is also a covered terminal strip for remote voltmeter sensing at the load in cases where the load is a substantial distance from the output terminals. This high quality, affordable bench power supply provides highly accurate output while allowing the user to precisely control the current.
