4. Persediaan dan Pemasangan
4.1 Pemasangan
The DRC-100A is designed for DIN rail mounting. It can be installed on TS-35/7.5 or TS-35/15 DIN rails. Ensure the unit is securely fastened to prevent accidental dislodgement.
4.2 Sambungan Pendawaian
Refer to the terminal block labels for correct wiring. The unit has input terminals for AC power, output terminals for DC load, and terminals for battery connection and alarm signals.
- Input (AC): Connect the AC input (100-240VAC, 50/60Hz) to the 'N' (Neutral) and 'L' (Line) terminals.
- Output DC: Connect the DC load to the '+V' and '-V' terminals. The primary output is +13.8VDC, 4.5A.
- Caj Bateri: Connect the backup battery to the 'Bat. +' and 'Bat. -' terminals. The battery charge output is +13.8VDC, 2.5A.
- Isyarat Penggera: The unit provides 'AC OK' and 'Bat. Low' alarm signals via relay contacts. Refer to the product label for specific pinouts.

4.3 Jldtage Pelarasan
Keluaran voltage can be adjusted using the '+V ADJ' potentiometer located on the front panel. Use a small screwdriver to carefully turn the potentiometer to set the desired output voltage dalam julat yang ditentukan.
5. Arahan Operasi
5.1 Hidupkan
After all connections are securely made, apply AC power to the unit. The 'DC OK' LED indicator will illuminate, indicating normal operation. If a battery is connected, it will begin charging.
5.2 Kefungsian UPS
The DRC-100A provides an Uninterruptible Power Supply (UPS) function. In the event of an AC power failure, the unit will automatically switch to battery power to maintain the DC output to the load. When AC power is restored, the unit will seamlessly switch back to AC power and resume battery charging.
5.3 Penunjuk LED
- DC OK: Illuminates when the DC output is within the normal operating range.
- AC OK: Illuminates when AC input power is present and within acceptable limits.
- Bat. Low: Illuminates when the connected battery voltage drops below a predefined threshold, indicating a low battery condition.
6. Penyelenggaraan
- Pembersihan: Keep the unit clean and free from dust. Use a dry, soft cloth for cleaning. Do not use liquid cleaners.
- Pengudaraan: Ensure adequate airflow around the unit for proper cooling. Do not obstruct the ventilation openings.
- Sambungan: Periksa semua sambungan pendawaian secara berkala untuk memastikan ia ketat dan terdapat tanda-tanda kakisan.
- Pemeriksaan Bateri: Regularly inspect the connected battery for any signs of damage or leakage. Follow the battery manufacturer's maintenance guidelines.
7. Penyelesaian masalah
