5.2 వైరింగ్ కనెక్షన్లు
Before making any connections, ensure the AC input voltage selector switch (115VAC/230VAC) on the front panel is set correctly according to your local mains voltage. Incorrect setting can damage the unit.
- Input Terminals (Bottom): Connect the AC mains supply to the L (Line), N (Neutral), and ⌂ (Ground) terminals. Use appropriate wire gauges for the current rating.
- Output Terminals (Top): Connect your load to the +V and -V terminals. Observe polarity. The "DC OK" LED will illuminate when the output voltage is within tolerance.
- వాల్యూమ్tagఇ సర్దుబాటు: A potentiometer (ADJ) is located on the front panel for fine-tuning the output voltage within a small range.

6. ఆపరేషన్
Once properly installed and wired, apply AC power to the input terminals. The "DC OK" LED indicator on the front panel will light up, indicating that the output voltage is present and within its specified range. The unit is now operational and supplying power to the connected load.
- ఓవర్లోడ్ రక్షణ: The unit features overload protection. If an overload occurs, the output voltage may drop or shut down. Reduce the load to restore normal operation.
- ఓవర్వోల్tagఇ రక్షణ: అవుట్పుట్ వాల్యూమ్ అయితేtage exceeds a preset limit, the unit will shut down to protect the connected equipment. Power cycling may be required to reset.
7. నిర్వహణ
The DR-120-12 power supply is designed for reliable operation and requires minimal maintenance. Regular inspection is recommended to ensure optimal performance and safety.
- శుభ్రపరచడం: Keep the ventilation openings clear of dust and debris to ensure proper airflow. Use a soft, dry brush or compressed air for cleaning. Do not use liquid cleaners.
