Product Features:

High - Reliability Design

1. True on - line double conversion is realized, providing a stable and clean power supply for your equipment.
2. Compatible with generator input (the generator capacity should be twice that of the UPS).
3. An output isolation transformer can be added according to user requirements (installed before leaving the factory).
4. Standard - equipped with EPO (Emergency Power Off device).
5. The machine is controlled by MCU + DSP chips, ensuring high - precision control and stable operation.
6. Supports parallel operation, with a maximum of 3 units in parallel (only for parallel - capable models).
7. The number of batteries (16 - 20) can be set according to on - site requirements.
8. The charging current (1 - 4A, default 4A per charging board) can be set on - site as needed.
9. This series has two models with power factors of PF0.8 and PF0.9.
10. Supports the function of automatic startup when mains power is restored (default is off).
11. After a power outage, when the battery is depleted, the UPS can automatically start up when the power comes back.

​

Comprehensive Protection for the Whole Machine

• It integrates multiple protection functions such as output overload protection, output short - circuit protection, inverter over - temperature protection, battery under - voltage pre - warning protection, and battery over - charging protection, greatly ensuring the stability and reliability of system operation.
• An optional manual maintenance switch is available. When the UPS fails, it can be seamlessly transferred to the bypass working state, and the mains power can continue to supply power to the load, making maintenance work easy, convenient, and fast.

​

Interface Management Function

• The LCD liquid - crystal display can record the UPS working status, parameter information, etc. in real - time, facilitating users to manage the UPS.

​

Network Monitoring and Management

• Through the RS232/RS485 communication interface and SNMP network adapter, and in conjunction with the UPS intelligent monitoring software, it can communicate with the computer. All kinds of UPS parameters are clearly displayed on the communication interface.

​

High Environmental Adaptability

• The circuit board is placed in a completely enclosed space and is treated with "three - proofing" coating, making it more suitable for harsh environments such as tunnels and squares.
