Product information "Thyristor actuator 3x phase controlled modulator, 4 ...20mA control, incl. cooling element"

Solid-state tyristor actuators, similar to solid-state relais, are being used for performance regulation of loads.Contrary to SSR-relais, the performance regulation is not carried out by tacting the output (pulse width modulation), but infinitely variable by a so-called phase controlled modulator of the sinus curve of the load current. Preferably, this technique is applied for infinitely variable regulation for ohmic loads (e.g. electrical heating).

Technical data

  • Phase controlled modulator 70 - 660VAC
  • Peak current 40A (per phase)
  • Performance up to 9kW (cooling element included in price)
  • Frequency 50 - 60Hz
  • Control signal 4-20mA

Advantages of the thyristor actuator:

  • Infinitely variable performance regulation of loads powered by high voltage (400V). Wiring can be done in Y-, parallel-, as well as delta-connection. Due to the regulaiton current, 4-20mA all 3 of the phases can be adressed simultaneously.
  • Wear resistant regulation due to lack of mechanical components.
  • Compact dimensions.
  • High switching power with high peak performance for inductive loads, as well as sufficient short-period capacity when using safety fuses.
  • Low loss performance under full load.

Note, that not all electrical loads can be controlled by a phase controlled modulator. Electrical heating, asyncron engines and similar loads can be easily targeted.
