Description:
ProgrammingSCR firing control and output regulation
Parameter and Alarm Indication
Interfacing with external PC or PLC
1. Operationmode: local/remote operation mode can be chosen
2. Outputcontrol mode: constant current/constant voltage output control;output control mode can be chosen
3. Softstart time: Working time of soft start can be set between0-200s
4. Constantcurrent/constant voltage control accuracy: controlaccuracy≤±0.5%
5.Rectification mode: silicon controlled phase-shifting voltageregulation rectification
6.Rectification pulse number: SCR 6 pulse rectifier, 12 pulse SCRphase-shifting regulation voltage rectifications
7. Inputcurrent ripple coefficient: 6 pulse rectifier≤5%, 12 pulserectifier≤1-3%
8.Human-computer operation interface: PLC colorful touchscreen
9. Siliconcontrolled trigger controller: DSP computer digital triggercontrol, trigger pulse asymmetry≤0.1°, pulse phase-shiftingresolution≤1μs (0.018 degree)
10.Main protectionfunctions: lack phase, overvoltage, under voltage, quick fuse orfuse alarm protection of AC power supply, output over current andcurrent limiting protection, output short circuit and instantaneousoverload protection, over temperature and overheat protection ofsilicon controlled components, rectification transformer and buscopper bar, overheating and high pressure protection of windmachine, low block trigger pulse protection
11.RS485 remotecommunication interface can be chosen according to customer’srequirement, remote monitor can be realized by Internet CAN busand PRUBSS bus communicationprotocol
12. With 1-5stage constant current slow rising & descending phase numbercontrol, every stage anodizing current and anodizing time can beset separately
13.Real-time record process parameters and curve of current, voltage,anodizing time and bath temperature etc
14. Store orwithdraw 5 sets of process parameter and shorten machining andprogramming time
15. Can beconnected with computer through RS485 communication interface, canbe stored by U disk then re-store to computer, it is convenient forcustomer to save file so as to analyze process quality of anodizingparts
16. 17. Ironcore of rectification transformer adopts good quality supermicrocrystalline material, no-load loss less than 2%, which is8-10% electric-saving comparing with common on-off rectificationtransformer
17.Local/remote control operation: remote operation control cabinetcan be choose according to customer’s situation on site, hose andremote control cabinet are placed separately, on-site operation ismore convenient, anti-corrosion protection of host increasedgreatly
18. Coolingmode: air cooling or water cooling can be chosen according tocustomer’s requirement
