Product Features
- Green & Ultra-High Efficiency: The equipment provides an industry-leading operating efficiency of over 99%, generating minimal heat to maximize savings on power and cooling costs.
- Maintenance-Free Supercapacitors: Utilizes supercapacitors as energy storage units, featuring an extremely long service life and a wide operating temperature range. It requires no subsequent maintenance and causes no environmental pollution.
- Ultra-Fast Voltage Correction: Delivers an extremely fast response to voltage sag events, with a detection time of less than 100μs, a normal response time of less than 5ms, and a typical complete response within 2ms.
- High Reliability & Redundant Design: Features N+1 redundancy for the auxiliary power supply. Models above 100kVA adopt a hot-swappable modular N+1 redundancy design, ensuring that equipment failure does not affect the load.
- Uninterruptible Maintenance System: Comes standard with a maintenance bypass switch and an automatic bypass system. In the event of a failure or during maintenance, the load continuously receives power from the grid without interruption.
- Space-Saving & Modular Design: Configured without energy storage batteries to significantly reduce the footprint. The hot-swappable modular design provides higher power density and facilitates subsequent maintenance.
- Intelligent Monitoring & HMI: Equipped with a color touch screen capable of recording various voltage events. It features one-click data download, remote monitoring capabilities, and supports the Modbus TCP/IP communication protocol.
