Main Features

The rectifier uses the active Power Factor Compensation(PFC) technology and the power factor is up to 0.99.

The power system has wide AC input voltage: 85Vac
～
300Vac.

The rectifier uses soft switching technology, raising the efficiency above 95.5
％
.

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 UL
，
CE and NEBS.

The rectifier is of high power density.

The rectifier is hot pluggable. It takes less than1 min to replace a rectifier.

The rectifier has two optional 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 controller module has perfect battery management. The management functions includes BLVD,
temperature compensation, auto voltage regulation , stepless current limiting ,battery capacity calculation and
on-line battery test, etc.

History alarm records
：
M221S/M222S controller supports 200 history alarms and 1000 history data records,
M225S controller supports 200 history alarms and 512 history data records. And M820B/M830B supports
historical alarm record up to 3000 pcs and historical record up to 60000 pcs.

Battery test data: can record up to 10 sets of battery test data.

The power system is of network design. Providing multiple communication ports (such as RS232, modem and
dry contacts), which enables flexible networking and remote monitoring.

The power system has perfect lighting protection at both AC side and DC side.

The power system has complete fault protection and fault alarm functions.

The power system uses " controller power-losing " control mode . In the indoor or outdoor equipment room
without guard and maintenance, the " controller power- losing mode" can protect the battery from deep
discharge.
