6.1 ສະບັບພື້ນຖານtage ແລະການຕັ້ງຄ່າປະຈຸບັນ

1. Ensure the power supply is on and no load is connected to the output terminals.
2. ການຕັ້ງຄ່າ Voltage: For CH1 or CH2, press the respective Voltage Adjustment Knob (14 or 7) to activate adjustment. Turn the knob to set the desired voltage. The 4-digit display allows for precise adjustments.
3. ການ​ຕັ້ງ​ຄ່າ​ປັດ​ຈຸ​ບັນ​: For CH1 or CH2, press the respective Current Adjustment Knob (17 or 6) to activate adjustment. Turn the knob to set the desired current limit.
4. ການ​ເຊື່ອມ​ຕໍ່​ການ​ໂຫຼດ​: ຫຼັງຈາກກໍານົດ voltage and current, connect your load to the appropriate output terminals (15 for CH1, 12 for CH2, 9 for CH3).
5. ເປີດໃຊ້ຜົນຜະລິດ: Press the CH1 Output Switch (5) or CH2 Output Switch (13) to enable power output to the connected load. The display will show the actual output voltage ແລະປະຈຸບັນ.

Note on Output Switch: When enabling output, especially with sensitive loads, there can be a brief current overshoot. It is recommended to set voltage and current limits with the output disabled, connect the load, and then enable the output. For highly sensitive circuits, consider using an external switch or connecting the load after the power supply has stabilized.

6.2 Series and Parallel Mode Operation

The MPS-3010H-3 allows for easy configuration of CH1 and CH2 in series or parallel mode:

1. ການກະກຽມ: Ensure both CH1 and CH2 outputs are disabled.
2. ເລືອກໂໝດ: Press the One-key Series/Parallel Function Button (18). The corresponding indicator light (19) will illuminate for either SERIES or PARALLEL.
3. Series Mode: In series mode, the output voltage of CH1 and CH2 adds up (e.g., 30V + 30V = 60V), while the current remains at the set limit of the master channel. The display will show the combined voltage ແລະປະຈຸບັນ.
4. ໂໝດຂະໜານ: In parallel mode, the output current of CH1 and CH2 adds up (e.g., 10A + 10A = 20A), while the voltage remains at the set limit of the master channel. The display will show the combined current and voltage.
5. ເປີດໃຊ້ຜົນຜະລິດ: After selecting the mode, enable the output for both channels.

6.3 Protection Functions (OCP/OVP/OTP)

• OCP (Over Current Protection): If the output current exceeds the preset limit, the power supply will enter constant current (CC) mode, limiting the current to the set value. The CC indicator will light up.
• OVP (Over Voltage ການ​ປ້ອງ​ກັນ​)​: ຖ້າຜົນຜະລິດ voltage exceeds a preset maximum, the power supply will shut down the output to protect the load.
• OTP (ການປົກປ້ອງອຸນຫະພູມເກີນ): If the internal temperature of the power supply exceeds a safe operating limit, the unit will automatically shut down to prevent damage.

6.4 ການຕັ້ງຄ່າອື່ນໆ
