Circuit Specialists 30 Volt, 20 Amp DC Power Supply

The CSI3020SW is a compact, efficient switching benchtop power supply with adjustable voltage and current output.

The CSI3020SW is a compact, efficient, switching bench power supply with a powerful, accurate output designed to deliver up to 20 amps of current into any voltage up to 30VDC. Voltage and current can be read via the large, clear backlit LCD. Output can be fed to the front panel mounted banana plug terminated jacks or from a pair of heavy duty terminals at the rear of the small footprint chassis. Both voltage and current can be easily adjusted via a pair of large, tactile, front panel knobs. In addition to a rear panel mounted fuse, the CSI3020SW has constant current protection, over temperature thermal protection (via a rear exiting, thermostatically controlled internal fan), and output over voltage protection to ensure reliability and safe operation for both the power supply and any connected load.
