Wide Input Voltage Range
The wide input voltage range of 90–300VAC helps the UPS operate reliably in unstable mains power environments.
High Input Power Factor
Input power factor ≥0.99 helps improve electrical efficiency and reduce impact on the upstream power system.
Precise Output Voltage Regulation
Output voltage regulation of ±1% provides stable power for connected critical loads.
Zero Transfer Online Operation
Online double-conversion operation provides continuous output power without transfer interruption during mains power disturbances.
Strong Overload Capability
The UPS supports short-term overload conditions, including 105%–125%, 125%–150%, and over 150% protection response levels.
LCD and LED Display
LCD and LED display options show key UPS information such as mains status, battery status, load level, battery level, operation mode, input voltage, frequency, and health status.
RS-232 Communication
Standard RS-232 communication supports UPS monitoring and system communication.
Optional Monitoring Cards
Optional NMC card, MODBUS-485 card, USB card, and dry contact card support remote monitoring, industrial communication, and alarm integration.
Quiet Operation
With noise level below 55dB at 1 meter, the UPS is suitable for offices, network rooms, and small IT environments.
