DC screen features:

The system adopts a unique “one-line access” wiring technology, which greatly facilitates the on-screen wiring of the large-capacity DC system and facilitates user maintenance.

● The natural cooling mode of the charging module greatly improves the average time between failures, and can be used in places where the environment is relatively harsh.

● The charging module can be hot swapped, and the average repair time is greatly reduced.

● Adopting the latest international soft switch technology, the main devices use high-quality brand-name products.

● Battery automatic management and protection, real-time automatic monitoring of the battery's terminal voltage, charge and discharge current, and control the battery's average charge and float charge, with battery over-voltage and charge over-current sound and light alarm.

● The device can be programmed via the public telephone line for remote maintenance diagnosis.
