3.2 Кубат туташтыруу
- Ensure the power supply's input voltage setting (if applicable, check the rear panel for a voltage selector switch) matches your local mains voltage (110V же 220V).
- Connect the provided power cord to the power input socket on the rear panel of the power supply.
- Электр шнурунун экинчи учун жерге туташтырылган электр розеткасына сайыңыз.
3.3 Output Connection
- Before connecting any device, ensure the power supply is turned off and the voltage and current knobs are set to their minimum positions.
- Connect the red output cable to the positive (+) terminal and the black output cable to the negative (-) terminal on the front panel. The green terminal is for ground (GND).
- Connect the other ends of the output cables to your load device, ensuring correct polarity.
4. Иштөө нускамалары
4.1 Күйгүзүү/өчүрүү
- Press the 'POWER' button on the front panel to turn the unit ON. The digital display will illuminate.
- Press the 'POWER' button again to turn the unit OFF.
4.2-томtage Тууралоо
- Use the 'COARSE' knob for Voltage (V) to make large adjustments to the output voltage.
- Use the 'FINE' knob for Voltage (V) to make precise, small adjustments to the output voltage.
- Voltage reading on the digital display.
4.3 Current Adjustment (Current Limit)
- Use the 'COARSE' knob for Current (A) to set the approximate current limit.
- Use the 'FINE' knob for Current (A) to set the precise current limit.
- The power supply will operate in Constant Voltage (CV) mode until the load draws current exceeding the set limit, at which point it will switch to Constant Current (CC) mode.
- Monitor the current reading on the digital display.
4.4 USB чыгышы
- The front panel features a 5V/2A USB output port.
- Connect compatible USB devices for charging. This output is independent of the main adjustable DC output.
