01.

Fully modular design

“Plug-and-Play” modular design (divided into SDP and MDP series): the rectifier unit, inverter unit, and isolation diodes are integrated into a single module, enabling easy plug‑and‑play replacement and significantly reducing maintenance time.

02.

Fully redundant design

Multiple power modules operate in parallel, achieving N+1 redundancy. The control power supply, the microprocessor on the main control board, and the cooling fans all feature dual-redundant designs, ensuring that a single thermal or electrical failure will not compromise system operation. Output voltage regulation employs a 1+1 redundant closed-loop control scheme, guaranteeing that even if one feedback path fails, no overvoltage will be generated to damage the load.

03.

Multi-language LCD display (Chinese, English, Russian, Spanish)

Large-screen LCD display, UPS monitoring software with multi-language support, simple and intuitive operation, no language barriers, and easy to learn.

04.

Fully digital control

Employing control switching components such as DSPs and IGBTs: ensures system stability and enhances mechanical efficiency.

05.

Intelligent Parallel Hot Backup

No paralleling board is required; a single communication cable suffices to enable multiple hosts to operate in parallel with redundancy. The communication cables between the parallel hosts are arranged in a ring topology, forming a closed loop—so even if one cable is severed, it does not disrupt multi‑stage parallel operation.

06.

Human-centered control design

There are no rigid procedural restrictions; operation is straightforward, unlike other brands of UPS that impose strict operating‑procedure constraints.

07.

Ultra-wide input voltage range

Under full-load conditions, the input voltage range is exceptionally wide—300 VAC to 520 VAC—and even when most UPS systems rely on battery discharge to maintain stable output voltage, these units can still operate as usual.

08.

Intelligent detection and speed control of cooling fans

Any fan malfunction can be monitored via the UPS panel or through the RS‑232 interface. The fan speed automatically adjusts according to the load, extending the fan’s service life and reducing noise.

09.

The static switch has an extremely short switching time, enabling seamless, disturbance-free switching.

Employing 32-bit DSP digital control technology and a current‑mode detection method, the switching time is reduced to 0.

10.

Data recording capability

All data and timestamps associated with abnormal conditions are stored in the UPS, enabling users to clearly monitor any issues that arise. Even during a power outage, the data retained in the UPS remains intact.

11.

Remote Diagnosis and Testing

Remote diagnostics and testing of multiple UPS systems are available via the Internet, ensuring your system operates at peak reliability at all times.

12.

Intelligent Communication Interface

One RS‑232 port, four RS‑485 ports, and standard communication protocols comprise the intelligent monitoring system. It also supports SNMP devices for remote network management. More than 20 pairs of passive dry contacts are available for flexible configuration and use.
