4.1 ການເປີດ/ປິດ

• To power on, flip the main power switch on the rear panel to the 'ON' position.
• To power off, flip the main power switch on the rear panel to the 'OFF' position.

ສະບັບທີ 4.2tage ແລະການປັບຕົວໃນປະຈຸບັນ

The HY3005B uses encoder adjustment knobs for precise control:

1. ການປັບຕົວຫຍາບ: Rotate the VOLTAGE or CURRENT knob to adjust the respective value. The display will show the whole number changing.
2. ການປັບຕົວລະອຽດ: ກົດປຸ່ມTAGE or CURRENT knob briefly. The decimal portion of the display will flash, indicating fine adjustment mode. Rotate the knob to adjust the decimal value. Press the knob again to exit fine adjustment mode.

4.3 Constant Voltagຮູບແບບ e (CV) ແລະ ກະແສໄຟຟ້າຄົງທີ່ (CC)

• Vol ຄົງທີ່tagໂໝດ e (CV): ໃນເວລາທີ່ຜົນຜະລິດ voltage is stable and below the set current limit, the power supply operates in CV mode. The 'CV' indicator LED will be lit.
• ຮູບແບບກະແສໄຟຟ້າຄົງທີ່ (CC): If the load current reaches the preset current limit, the power supply automatically switches to CC mode. The 'CC' indicator LED will be lit, and the output current will be limited to the set value.

4.4 Output Switch Control

The output switch allows you to set voltage and current limits before applying power to your circuit, preventing accidental damage.

ຮູບທີ 4.1: Close-up of the output switch on the HYELEC HY3005B, designed to prevent damage by allowing voltage and current settings before connecting the load.
