AC Uninterruptible Power Supply (UPS) Systems 

Product Overview

All UPS products in this series utilize high-frequency, online double-conversion technology, with capacities ranging from 1 kVA to 500 kVA. They are widely applicable across various industries—serving small, medium, and large-scale data centers—and are also suitable for fields such as industrial control, transportation, telecommunications, energy, and laboratory research. These systems provide users with a stable, secure, and reliable source of high-quality uninterruptible power.

Low-Frequency (Industrial Frequency) UPS Systems

These systems employ advanced DSP (Digital Signal Processing) control technology to enable real-time control, parameter configuration, operational program management, self-diagnostics, and self-detection functions. This technology allows for the comprehensive monitoring and fault protection of every independent circuit connection on the circuit boards.

User Interface

A large LCD touchscreen is provided as the standard display interface for the main unit. Users can select between Chinese and English language settings for the display content, ensuring that operational status, procedural steps, data acquisition logs, and fault detection information are all visible at a glance. Based on the specific load characteristics at the customer's site, the UPS can be configured via the LCD control panel to operate in ECO (Energy-Saving) mode. Should the system detect a deterioration in the quality of the utility power supply, the UPS will automatically switch to inverter mode to power the load. In ECO mode, the overall efficiency of the UPS unit exceeds 98%.

Parallel Operation Technology

Flexible parallel operation technology makes these systems adaptable to a wide variety of loads and system architectures. They support both 1+1 parallel operation (for capacity expansion or redundancy) and multi-unit (N+X) redundant parallel operation, thereby providing comprehensive and reliable protection for critical loads.

Cold Start Function

In the event of a complete loss of utility power input, the UPS can be manually activated to provide emergency power. To initiate this "cold start" process, the user simply needs to press the small DC start button located on the unit's cabinet, thereby enabling the UPS to supply power to the connected load.

Connectivity and Monitoring

The systems come standard with RS232, RS485, and USB communication ports, as well as various dry contact signal interfaces and expandable intelligent slots. This comprehensive connectivity suite enables true multi-purpose communication capabilities and facilitates effective remote monitoring.
