Built For Critical Power
True Double Conversion
IGBT-based rectifier and inverter topology ensures complete electrical isolation from mains. Zero transfer time protects against all power anomalies.
🔁
DSP Digital Control
Advanced Digital Signal Processor-based control for precise voltage and frequency regulation, fast dynamic response, and superior waveform quality.
📊
LCD Display
Multi-function LCD panel provides real-time monitoring of input/output voltage, frequency, load percentage, battery status and fault history.
🔋
Extended Battery Support
Compatible with external battery banks for extended runtime. Intelligent battery charger with temperature compensation maximizes battery life.
🌐
RS-232 Communication
Remote monitoring and management via RS-232 serial port for seamless integration with building management systems and monitoring software.
🌀
Active Power Factor Correction
Input PFC technology achieves input power factor >0.90, minimising reactive power and reducing stress on upstream generators and distribution.
🛡️
Wide Input Voltage Range
Operates on input voltage from 330V to 480V (3Ph), reducing battery discharge during brownout conditions and extending battery longevity.
🔧
Maintainable Online
Manual bypass switch allows for safe maintenance without interrupting the load. Hot-swappable fans and modular design minimize downtime.
