Control unit six pulse, digital


Trigger pulse generator with analogue and digital interface (8 bit) for connection to personal computer with CASSY interface in line-commutated, single-phase and three-phase rectifier and inverter circuits, as well as in AC and three-phase controllers. The control unit is adapted to the converter circuit using several switches with the following options:
  • Single pulse or pulse train operation possible
  • Secondary pulse can be switched off (after 60°)
  • Phase shift can be set for various natural
    commutating points: 0°, 30°, 60°
Reliable gate triggering of the valves is guaranteed for even small loads thanks to powerful gate trigger pulses and large voltage-time areas (500 µVs) of the trigger pulse. Rotating field monitoring:
  • Green LED when rotating field is clockwise
  • Red LED when rotating field is anti-clockwise
    or for phase failure.

Technical data

  • Signal output for rotating field monitoring (can be OR-operated with the pulse inhibit input)
  • 3 x 2 electrically isolated pulse outputs
  • Pulse inhibit input
  • Synchronising voltage: 1...440 V AC
  • Input control voltage: 0...10 V DC for
    control angle 180°...0°
  • Digital interface: TTL-level, 8-bit resolution for 180°
  • Supply voltage: ±15 V DC
