Description

Transistor pulse converter with voltage link for the generation of a three-phase, frequency and amplitude-variable output voltage from an AC mains. This unit in conjunction with the corresponding control unit is used to assemble a frequency converter or servo amplifier.

Technical description:
  • Single-phase mains connection
  • Variable link voltage due to fully controlled B2C rectifier bridge circuitry
  • Three-phase inverter built with IGBT (insulated gate bipolar transistor)
  • Maximum switching frequency 20 kHz, resulting in good approximation of sinusoidal current as well as low noise build-up in the machine
  • Output short-circuit-proof, earth-fault-proof and switch-proof
  • Interface for connection of the control unit (25-pin sub-D socket, TTL level)
  • Each individual transistor can be switched on and off via the interface and is protected from damage with an interlocking device
  • The respective activated IGBT's are displayed via LEDs
  • Monitoring of the variable link voltage, temperature rise in machines and converter, excess currents in the rectifier and converter. Output of the switching status via interface and display via LEDs
  • Integrated brake chopper
  • Safe galvanic isolation (SELV) between the power component and the control unit
  • Output currents are detected via Hall generators. Electrically separated output via interface
  • Two-stage mains filter for the reduction of the line-bound interference
  • Three-phase motor filter for the reduction of the edge steepness of the pulse voltages at the converter output to values < 250 V/µs

Technical data

  • Output voltage (UA): 3 x 0...230 V
  • Output current (IA): max. 3 x 8 A
  • Supply voltage: 200...240 V, 50/60 Hz via 4 mm safety sockets
  • Maximum switching frequency 20 kHz

Scope of delivery

  • 25-pin connection cable
