Product Description

Natural Cooling Input 380VAC 3 Phase Output 220VDC/20A Rectifier Power Charger 

 

“SD” series intelligent high-frequency switch power supply modules are specially developed to meet the demands of modern DC system. The charger rectifiers are designed with world leading patent technology “resonant voltage type soft switching power supply technology”. They feature high efficiency and stability, intelligent control, small size and light weight. Standard RS-485 interface, easy to connect with automation system. “Four remotes” functions, intelligent management. The products are widely used in power plant, substations and etc.

 

Main characteristic of the module

Modularization design, realize N+1 backup;

The friendly man-machine interface. Large screen to show, realize man-machine dialogue operate really.

RS-485 inrerface, realize “4 remote” function with monitor machine.

High efficiency, Nearly 95%-96%;

Lightly, 230V/10A natural cooling module only 9kg;

Little volume, 230V/10A natural cooling module dimension only 325mm×230mm×130mm;

After the full bridge rectifying circuit rectifies 3-phase AC to DC, then adjusted by reactive PFC, power factor>0.94;

Function against reverse pour: each module has been added diode against reverse pour at output terminal.

LED digital screen, digital calibrate, stable current ,fault alarm

 

Main characteristic of the Modules

  • The friendly man-machine interface. LED digital screen, digital calibrate, stable current ,fault alarm
  • High efficiency, up to 95%-96%;
  • Light weight, Small size
  • After the full bridge rectifying circuit rectifies 3-phase AC to DC, then adjusted by reactive PFC, power factor>0.94;
  • Unequal current ratio of parallel connection+/-3%, can ensure twenty modules work well by parallel connection.
  • Multiple protections including over/under voltage, current limiting, short-circuit, parallel protection, over-temperature protection.
  • Output over-voltage protection

To prevent the disastrous accident caused by output overvoltage, there is overvoltage protection circuit in the module. Once the output voltage is higher than the threshold, the module locks up automatically and fault indication light is on, the faulty module quits work automatically and doesn’t affect the normal operation of the entire system.

  • Output current limiting protect

The output current cannot increase infinitely. The maximum value of the output current of each module is limited to the rated output current 105%, in this range, the output current value of the module is continuously adjustable. If the load output of the module, the module will play down the output voltage.

  • Output short-circuit protection

When short circuit, the output voltage drops to 0 immediately. Limit the short circuit current under 15% of rated output current. The module will not be damaged under short circuit state for a time, and resumes to work automatically after debugging. 

  • Module parallel protection

There is parallel protection circuit in each module to ensure that when the fault module quits the system, the normal work of other modules and the system won’t be effect.

  • Output over-current protection

The output current cannot increase infinitely. If overloaded, the output voltage decreases automatically to protect the power components. The over current protection can be resumed automatically.
