1.3 Features

The rectifier uses the active Power Factor Compensation (PFC) technology, raising the power factor to 0.99.

The system has wide AC input voltage range: 90Vac ~ 290Vac.

The rectifier uses soft switching technology, raising the efficiency to 91%.

The rectifier has ultra-low radiation. With advanced EMC design, the rectifier meets international standards such
as CE, NEBS and YD/T983. Both the conducted and radiated interference reach Class B.

The rectifier safety design complies with UL, CE and NEBS standards.

The rectifier is of high power density.

The rectifier is hot pluggable. It takes less than 1min to replace a rectifier.

The rectifier has two over-voltage protection methods: hardware protection and software protection. The latter
one also has two optional modes: lock-out at the first over-voltage and lock-out at the second over-voltage.

The monitoring module has perfect battery management. The management functions include battery low voltage
disconnection (BLVD), temperature compensation, auto voltage regulation, stepless current limiting, battery
capacity calculation, on-line battery test, and so on.

The monitoring module can save up to 200 pieces of historical alarm records, and 10 sets of battery test data
records.

The monitoring module is of network design. With an RS232 port, Ethernet, dry contacts and other
communication ports provided, flexible networking is enabled to achieve remote monitoring and unattendance.

The system has complete fault protection and fault alarm functions.
