Adjustable 30 Volt, 20 Amp DC Power Supply

The CSI3020X is a fully regulated benchtop linear power supply with adjustable current limiting.

The CSI3020X is a regulated linear bench power supply with adjustable current limiting. The front panel LED display shows both voltage & current. The current output can be preset by the user via a front panel screwdriver adjustment screw while the voltage is adjustable by a front panel multi-turn knob for precise voltage settings. Output is by heavy duty front panel banana jacks and there is also a covered terminal strip for remote voltmeter sensing at the power source. This bench power supply provides precise outputs and allows the user to precisely pre-set the current output.
