Product Features

True 20kVA/20kW output with unity power factor
Delivers full-rated power output without derating, supporting high-density loads such as servers, medical equipment, and industrial systems.

Online double-conversion topology
Ensures consistent and isolated power supply, protecting connected equipment from surges, voltage fluctuations, frequency instability, and electrical noise.

Wide input voltage range with linear derating support
Operates across 100–280V input range, with linear derating between 100–175V at 50–100% load, offering stable performance in poor power conditions.

Flexible output voltage configuration
Supports multiple output voltage options including 200, 208, 220, 230, and 240 VAC (single-phase), making it adaptable to various regional power standards.

High efficiency up to 95.5% in normal mode
Reduces energy consumption and operational costs, with economy mode achieving up to 99% efficiency for maximum power savings.

Built-in hot-swappable batteries
Equipped with 20 x 9Ah batteries and scalable battery design to extend backup runtime without system downtime.

Advanced battery charging system
Supports configurable charging current from 1.5 A (default) to 8 A (maximum) for faster charging and longer battery life.

Multilingual graphic LCD display
Offers real-time system status, event logs, and alarm notifications through an intuitive interface.

Multiple output connection options
Includes 6 x IEC C13, 4 x IEC C19, 1 x terminal block, and 1 x managed IEC C19 port, enabling flexible and reliable load distribution.

Comprehensive communication interfaces
Supports integration into networked environments with USB, RS232, RS485, REPO/ROO ports, 4 dry contacts, and a MINI slot for expansion.

Low operating noise for quiet environments
Maintains a noise level below 50 dB, making it suitable for offices, labs, and other noise-sensitive settings.
