Circuit Specialists 50 Volt, 3 Amp DC Power Supply

The CSI5003XE is a fully regulated benchtop linear power supply with adjustable current limiting.

The CSI5003XE is a regulated, adjustable benchtop linear 50 volt power supply. For applications that require substantial voltage this unit can deliver up to 50 volts and 3 amps, and can be preset to any combination of the two. Power levels are displayed on a large, clear LED display that shows both voltage and current. The 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 via a pair of front panel banana jacks that accept typical 4mm bananna plug cables, if desired and there is also a covered terminal strip for remote voltmeter sensing at the power source. This bench power supply provides precise power output in a compact, affordable package.
