Chapter 2 Rectifier Modules

1. Introduction
Our rectifier modules adopt pure resonant soft-switching technology and Plug and play.
Each module is equipped with advanced microprocessors. On the front panel, each rectifier modules has 3 Led indicators: power supply indicator, communication indicator and failure indicator.

2.Functions：
●Soft switch
Rectifier power circuit is divided into active PFC and DC to DC converter which can make the wide input voltage range (75V-300V) and high efficiency (above 97%). High power density has reached the international advanced level. Efficiency curve is shown as below.

• Forced wind cooling
  Advanced design of Circuit makes for low-heating with heat sink.

• Hot swappable
  The monitoring module is hot-pluggable. When the module is plugged into the system, it will not cause the system output voltage fluctuations. Damaged modules can be replaced in less than 1min without stopping the system operation.

• Protection & failure alarm
  In different protection / fault types rectifier has different reaction / action mode.

• Auto equalized output in low-gap voltage of modules
  Adopted auto equalized output in low-gap voltage of modules technology. When the monitor module or individual rectifier is failure the other modules can maintain current sharing.

• Stepless limiting technology
  With stepless limiting technology, it can be continuously adjusted between rated current 0~110%

• Monitor
  Monitor has built-in CPU, monitoring the operation status of modules, and is responsible for the communication. The rectifier module receive ON/OFF current limit point and voltage setting sending by monitor through RS485, and send back the voltage, current,
  temperature limiting point ON/OFF status and alarm in real time to the monitor module.

• Fan control and dust-proof
  Stepless temperature control fan speed, and change with the output power of module, which minimize noise and extend fan life.

2.3 Control functions

The MINI System can release control signals according to the operation of the system.
Monitor module supports both automatic and manual battery management. Manual mode includes: equalized/float charging of battery groups, adjust rectifier modules voltage (it can change the system voltage), and set battery charging time. In automatic mode, the device will automatically complete the battery charge management according to charge interval and the specified date. When the system works, it can also change the charge mode (equalized or float charging). That is manual mode. In manual mode, all timing starts from zero, and continue to timing by the automatic mode, which can effectively prevent human operational errors to result in losses.

2.4 Complete communication functions
Host can monitor and control all the parameters, the status of the lower machine. At the same time, for safety and reliable, the host and the lower machine not only install the communication protocol to constrain each other, but also must know the monitor password of the lower machine, and sent it to the lower machine, when the host wanted to get the all parameters of the lower machines or monitor the lower machine. After the lower machine checked correctly, it can monitor and control. This is to ensure the stability of the power and avoid unnecessary losses caused by human.

2.5 Alarm & Record
Monitoring module has sound and light alarm function according to collect data and a corresponding action. The main alarms are emergency, main and minor.

2.6 Automatic battery management
Monitor module can implement various conservation measures to protect the battery, such as charging current limit, temperature compensation according to user set data, and charging current limit, average and float charge conversion time, average and float charge
voltage etc. battery charging methods.

2.7 Communication
Monitor module has the host and the lower device communication functions. It communicates with the host by RS232; communication with the lower device by RS485.

2.8 Dry contact output
