2. Product basic introduction
This rectifier is suitable for battery charging to provide stable DC power supply.
This rectifier adopts high frequency IGBT as semiconductor component and PWM modulation technology. It is modular structure design, easy to expand output current capacity, several rectifier modules could be connected in parallel and mounted in stack up to 20 modules to make more current. Single rectifier has independent power modules, each module could output independently or output in parallel connection.
The rectifier is made up with the following subassemblies:
IGBT inverter H bridge
High frequency transformer
Secondary Schottky diodes
Capacitors and inductors
Control and protection circuit and devices
Remote control box(optional)

1.Rectifier status indication
(1)Auto/Manual mode display
At left it is Auto mode, at right it is Manual mode
Auto mode: ; Manual mode:
At left it is CC mode, at right it is CV mode
When the rectifier is charging battery, the red light is on. When it is not charging, the color is grey.
When the rectifier finishes charging, the red light is on. Otherwise, the color is grey.
When there is no alarm, it shows red color continuously, when there is alarm, it is flashing.
It shows number of series connected cells.
l It shows the status of the rectifier, including:
Charging, charged, stop.
l When there is fault with battery, it will show battery status, including:
When actual battery voltage exceeds set max. Voltage*cell number, it will show incorrect battery voltage.
When actual battery voltage is lower than set min. Voltage*cell number, it will show no battery.
The min. and max. voltage is set on touch panel parameter setting page.
