Product Features

8kVA / 8kW full power capacity
Supports full active power output with a unity power factor (1.0), ideal for modern IT loads and high-efficiency infrastructure.

Online double-conversion topology
Ensures true power protection by isolating connected loads from grid disturbances, voltage fluctuations, and frequency anomalies.

Wide input voltage range with derating support
Accepts 100–280V input and provides linear derating performance between 100–175V at 50–100% load, enhancing reliability in unstable grids.

Multiple configurable output voltages
Selectable output voltages (200, 208, 220, 230, 240 VAC) to support diverse equipment requirements and global compatibility.

High operational efficiency
Offers up to 95.5% efficiency in normal mode and up to 99% in economy mode, significantly reducing energy costs.

Extended runtime with 20x9Ah batteries
Built-in battery pack with scalable runtime, ensuring continued operation during extended outages. Runtime can be extended further using external battery modules (VBMs).

Intelligent battery charging
Supports default 1.5 A charging current, configurable up to 8 A to optimize charge time and battery longevity.

Low voltage total harmonic distortion (THD)
Maintains <2% THD on output (with linear load) for clean and stable voltage delivery.

Overload protection
Operates continuously up to 105% load, supports 5 minutes at 106–125%, 1 minute at 126–150%, and 500ms for >150% overloads.

Flexible output interfaces
Includes IEC C13, IEC C19, terminal block, and a managed IEC C19 outlet for intelligent load control.

Multilingual LCD interface
User-friendly graphical display provides real-time status updates, alerts, and system diagnostics.

Advanced communication interfaces
Supports remote monitoring and integration with power management systems via USB, RS232, RS485, MINI slot (for SNMP), REPO/ROO port, and dry contact interfaces.

Optimized for environmental conditions
Operates in ambient temperatures up to 55°C and relative humidity up to 95% (non-condensing), making it suitable for harsh environments.
