220Vac to 48Vdc 50A 2900W rectifier

1.Power rectifier system introduction :

 AC DC rectifier system is consisted by one rectifier module or multiple rectifier modules and monitor

 modules. The power of rectifier systems can be different by different quantity rectifier modules.

 This rectifier system converters high voltage AC to DC24V or DC48V use for special DC equipment

 load. High efficiency>96%.

Remark:Some rectifier system need rectifier modules,monitor and distribution;some system only need 

rectifier modules.ACDC rectifier system can supply DC power for DC load and charging for battery at

 the same time.

2.Product Features:

1. Circuit of the Rectifier modules have two parts,one is PFC adjust; the other is DC/DC transformation.All 

technically m ake the wide  voltage range (85V-290V).

2. High efficiency.rectifier modules used soft switch technology,while load rate10% then efficiency can be  

91%,50% load rate the efficiency can be above 96%                

3. With step less current limiter technology,output current is continuously adjustable.

4. Adopted step less temperature control speed,it can reduce power consumption and prolong the life of the fan.

5. Sharing Load, Equalized-current imbalance ≤ 3%

6. Optional Ethernet interface through SNMP and/or TCP/IP

7. Controller MCU

8. Digital signal collection via internal RS485 bus; RS232 interface for remote operation

9. 2U height, light weight, High power density.

4.The detailed introduction:

5.Monitoring module:

 monitoring module monitors the working status of each rectifier module,has functions of collecting,displaying and setting the operation parameters of the system.it can also communicate with an external computer and form a loacl or remote centralized monitoring system.

Monitoring content:

•LCD display

•Through the system menu set the relevant parameters

•Alarm and recording function
 

6.Distribution unit:

 •shunt load with short-circuit and overcurrent protection,shunt capacity can be adjusted according to user requirement.

•battery should connect with an external fuse protector.

•power off auto/manual,load off on/off control switch,etc.

•battery current, the total load current can be detected

•al dc outputs have fault detection function

•LVDS2 function to protect load and battery

•capacity of MCB in each channel is 50A
