Circuit Specialists 120 Volt, 1.0 Amp DC Power Supply

The CSI12001X is a fully regulated benchtop linear power supply with adjustable current limiting.

The Circuit Specialists CSI12001X is a high stability, linear bench power supply featuring an LCD digital read-out, and constant voltage and current output modes. Short circuit and current limiting protection are provided in addition to an onboard cooling fan. SMT PC boards and built-in thermal protection help ensure reliable performance and long life. This unit is the perfect choice for lab and educational use where 120V operation is required. This bench power supply provides an adjustable output of 0-120 volts and can deliver current up to 1 amp. Expertly manufactured, this Circuit Specialists house branded version compares with bench power supplies costing twice as much.

Voltage levels are displayed on a large, clear LCD display that shows both voltage & current. The current output can be adjusted via front panel switches, while the voltage is adjustable by a large front panel multi-turn knob for precise settings. Output is via a pair of front panel banana jacks, additionally there is a covered terminal strip for remote voltmeter sensing at the load.
