Product Overview
The WattPower UPS Power System is a high-reliability, double-conversion online uninterruptible power supply designed for mission-critical loads in substations, data centers, industrial plants, and commercial facilities.
With zero transfer time, high output power factor (0.9/1.0), intelligent battery management system (BMS), and comprehensive communication capabilities including IEC 61850, it ensures seamless power protection for critical equipment — eliminating downtime risks from grid disturbances.
Key Features
- Double-Conversion Online Topology — True double-conversion design with zero transfer time (0ms) from bypass to inverter, providing the highest level of power protection
- High Output Power Factor — Output power factor of 0.9 / 1.0 (model dependent), delivering more real power to critical loads compared to standard 0.8 PF UPS units
- Intelligent Battery Management — Temperature-compensated charging, automatic battery test, deep-discharge protection, and battery health monitoring for extended battery life
- Wide Input Voltage Range — Broad input voltage range (380V AC ±25%) minimizes battery usage, extending battery service life and reducing maintenance
- Comprehensive Communication — RS485/RS232/Ethernet with MODBUS, IEC 60870-5-103, and IEC 61850 protocol support for substation and industrial automation integration
- Parallel Redundancy (Optional) — N+1 parallel redundant operation for increased system reliability and capacity expansion without downtime
