KGDF(S)-12ZH-Series Silicon Controlled Electrolysis Rectifier

KGDF(S)-12ZH-Series Silicon Controlled Electrolysis Rectifier
Product Detailed
1.High stability,small volule,light weight 2.High efficiency and energy-saving 2.Electrolytic zinc rectifier PLC or manual

Main Technical Features and Performance Index

1. Operation mode: local/remote operation mode can be chosen

2. Output control mode: constant current/constant voltage output control; output control mode can be chosen

3. Output reversing mode: silicon controlled contactless reversing, one time reversing and automatically periodic reversing

4. Soft start time: Working time of soft start can be set between 0-200s

5. Constant current/constant voltage control accuracy: control accuracy≤±0.5%

6. Rectification mode: silicon controlled phase-shifting voltage regualtion and rectification

7. Rectification pulse number: SCR 6 pulse rectification, 12 pulse SCR phase-shifting voltage regualtion and rectification

8. Output current ripple coefficient: 6 pulse rectifier ≤5%, 12 pulse rectifier≤1-3%

9. Silicon controlled trigger controller: DSP computer digital trigger control, trigger pulse asymmetry≤0.1°, pulse phase-shifting resolution≤1μs (0.018 degree)

10. Main protection functions: lack phase, overvoltage, undervoltage, quick fuse or fuse alarm protection of AC power supply, output overcurrent and current

limiting protection, output short circuit and instantaneous overload protection, over temperature and overheat protection of silicon controlled components,

rectification transformer and bus copper bar, overheating and high pressure protection of wind machine, low block trigger pulse protection

11. RS485 remote communication interface can be chosen according to customer’s requirement, remote monitor can be realized by Internet CAN bus and PRUBSS bus communication protocol

12. Rectification transformer adopts three-core five-column structure, iron core uses good quality oriented silicon steel sheet, tranformer coil are all copper, no-load

loss less than 2%, 8-10% power-saving comparing with common three-phase three column rectification transformer

13. Local/remote control operation: remote operation control cabinet can be choose according to customer's situation on site, hose and remote control cabinet

are placed separately, on-site operation is more convenient, anti-corrosion protection of host increased greatly

14. Cooling mode: air cooling or water cooling can be chosen according to customer's requirement
