120 Volt DC 1.0 Amp Linear Bench Power Supply

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.

For more information, refer to the CSI12001X DC Power Supply's Owners Manual.

This power supply's output is always on, so be very careful to ensure no high voltage short circuit takes place as it will likely ruin the unit.

To set the current maximum, press the cc/cv button until the LED is off. Then adjust the voltage knob to a voltage level of a few volts. Connect a wire from the positive terminal to the negative terminal. The power suplply should automatically trigger to CC and show the current output. Press then cc/cv button to set the power supply into cc fixed mode, and use the up and down buttons to set the current maximum. (Procedure video)
