Overview

The UPS uninterruptible power supply consists of a rectifier, inverter, static bypass switch and battery pack. When mains power is abnormal, the battery immediately supplies power via inversion to achieve zero or near-zero power interruption. It stabilizes voltage and filters grid surge interference.

Classified by application scenarios, it includes line-frequency UPS, high-frequency UPS and modular UPS. The UPS system is composed of a UPS main unit, battery pack, input power distribution cabinet, output power distribution cabinet and other components, with a capacity range from 10kVA to 400kVA. Designed to high industrial standards, it adopts copper bars for internal electrical connection and copper post secondary fastening technology, completely eliminating internal connection faults caused by transportation. It can withstand 20,000 volts high voltage, featuring neat wiring, elegant structure and good heat dissipation, together with comprehensive detection and protection functions.

Product Features

▲ Advanced redundant parallel technology (supports up to 8 units). Units of different power capacities can be paralleled and share the same battery bank (bid evaluation point). ▲ Capable of networking and grid connection with IT isolated power supplies. ▲ Dual-core DSP full digital control.

1. Double-conversion online topology

2. Wide input voltage range

3. Three-phase separate regulation for balanced voltage stabilization

4. Mains power startup function

5. 6th-generation IGBT devices plus advanced SVPWM (Space Vector Pulse Width Modulation) technology

6. Battery self-test function (testable without cutting off mains power)

8. User-friendly human-machine interface equipped with a 7-inch large-screen Chinese-English touchscreen plus LED display; the number of battery cells can be set via the LCD panel.

9. Abundant network monitoring interfaces: RS232, RS485, RJ45 and dry contacts. Wi-Fi is optional, enabling intelligent monitoring of UPS equipment via mobile phones or tablets.

10. Built-in manual maintenance bypass.

11. Unique UPS timed on/off function and sleep function

• Timed on/off: the UPS can be scheduled to power on and off as required by users.

• Sleep function: under light load, the UPS automatically switches to bypass mode and returns to inverter power supply when the load increases.

12. EPO (Emergency Power Off) function

13. Intelligent temperature-controlled fans for long service life and low noise
