5.1. Setting Voltage жана Current

The Jesverty SPS-12003 allows for precise adjustment of both voltage жана учурдагы чектөөлөр.

  • Жөндөө Voltage: Use the V-COARSE (6) knob for large voltage changes and the V-FINE (8) knob for precise adjustments. Turn clockwise to increase, counter-clockwise to decrease.
  • Токту жөндөө: Use the A-COARSE (7) knob for large current changes and the A-FINE (9) knob for precise adjustments. Turn clockwise to increase, counter-clockwise to decrease.
  • Setting Limits Before Connecting Load: Керектүү томду коюу сунушталатtage and current limits before connecting your device. Turn the current knob fully clockwise to set the maximum current limit. Adjust the voltage to your desired level. Then, connect your load. If you need to limit the current, slowly turn the current knob counter-clockwise until the desired current limit is reached. The C.C. indicator will light up when the current limit is active.

5.2. Constant Voltage (C.V.) and Constant Current (C.C.) Modes

The power supply automatically switches between C.V. and C.C. modes depending on the load conditions.

  • Constant Voltage (C.V.) Mode: When the load resistance is high, the output voltage remains constant at the set value, and the output current varies according to the load. The C.V. indicator (4) will be lit.
  • Constant Current (C.C.) Mode: When the load resistance is low, the output current remains constant at the set value, and the output voltage varies according to the load. The C.C. indicator (5) will be lit. This mode protects the connected device from excessive current.
