Aircooled electronic DC power-supplies up to 4.000A

  • thyro-power-lk

 

GENERAL

The rectifier construction of the production series RGB-Thyro-Power-LK for electrophoretic painting is charaterized by the components mains-transformer, power-switch, Thyristor-stack in B6C (secondary), currentlimitation, smoothingchoke and PLC-control. All process relevant signals will be displayed, controlled and transmitted by RGB software.

  • Single rectifiers from: UDC = 100 - 1.000V / IDC = 100 - 4.000A

TECHNICAL DATA

  • Mains: 3x400V / 50Hz (worldwide mains-conditions possible)
  • Regulation: voltage regulation with subordinated currentlimitation (stepless 0...100%)
  • Current limitation: 20 - 100% stepless adjustable
  • Control: SPS - Display with interface for master-control unit.
  • Ripple: < 5% of nominal DC-voltage
  • Rectifier connection: 6-pulse rectifier-connection (B6C)
  • Cooling: forced aircooling
  • Temperature: +35°C (higher temperature conditions possible)
  • Detection: phase position; phase rotation; phase loss; mains low voltage; short-circuit detection; temperatures; fuses
  • Signals: current, voltage, status, fault-signals
  • Operation mode: 100% duty cycle
  • Degree of protection: IP20
