4.1 ເປີດ/ປິດ
- Once all connections are secure, apply input power to the unit.
- The "DC OK" indicator LED will illuminate when the output voltage ຢູ່ໃນຂອບເຂດທີ່ກໍານົດໄວ້.
- To power off, disconnect the input power.
4.2 ຜົນຜະລິດ Voltage ການປັບຕົວ
ຜົນຜະລິດ voltage can be adjusted from 24V to 30V using the potentiometer located on the front panel.
- With the unit powered on and under no load, use a small, insulated screwdriver to carefully turn the "V ADJ" potentiometer.
- Turn clockwise to increase the voltage, ທວນກັບເຂັມໂມງເພື່ອຫຼຸດລົງ.
- ຕິດຕາມກວດກາຜົນຜະລິດ voltage with a multimeter to ensure it is set to the desired level.
5. ບໍາລຸງຮັກສາ
The MDR-60-24 power supply is designed for long-term, reliable operation with minimal maintenance. However, periodic checks are recommended:
- ທໍາຄວາມສະອາດ: ຮັກສາເຄື່ອງໃຫ້ສະອາດ ແລະບໍ່ມີຂີ້ຝຸ່ນ ແລະສິ່ງເສດເຫຼືອ. ໃຊ້ຜ້າອ່ອນໆ, ແຫ້ງເພື່ອທໍາຄວາມສະອາດ. ຢ່າໃຊ້ນໍ້າສະອາດ.
