Flexible environmental adaptability

•The UPS is designed for harsh electrical environments, with a wide input voltage range of 165–275 VAC for 1-phase in/1-phase out models and 285–475 VAC for 3-phase in/1-phase out models. Its broad 40–70 Hz input frequency range ensures compatibility with unstable grids and fuel generators.

•It supports mixed loads and offers strong overload capability for reliable operation under demanding conditions. Output voltage and frequency are configurable, supporting 220/230/240 V and 50/60 Hz to meet different application requirements.

Reliable dual-DSP control

•With dual-DSP control and an independent bypass power supply, the system monitors the main DSP in real time. In case of abnormal operation, the UPS automatically transfers to bypass mode and triggers an alarm, ensuring continuous power supply for critical loads.

Configurable and high-efficiency charging system

•Charging current is easily configurable via DIP switches, offering precise settings of 2A, 4A, 6A, 8A, 10A, and 12A to suit various battery configurations. For models rated at 10kVA and above, the system supports dual parallel charging panels, enabling a robust maximum charging current of up to 24A for significantly reduced recharge times.

Supports dual input, series hot standby, and parallel operation

•This UPS supports dual input, series hot standby, and parallel operation configurations. These features are designed for straightforward implementation and ease of use, significantly enhancing overall system reliability and scalability.

Intelligent rectifier protection

•The system continuously monitors the rectifier's input voltage. In the event of an overvoltage condition, it automatically disconnects the rectifier to effectively isolate and safeguard the inverter from potential damage.

Diversified communication modes

•Standard communication interfaces include RS232 and USB. Optional interfaces include RS485, SNMP and dry contacts.
