Triggering board for Thyristors

COUGAR ELECTRONICS has a full range of triggering boards for thyristors press pack applications.

ARCTI CP – 3kV insulation

The ARCTI-CP board enables to dispatch control pulses to 2 thyristors. A pulse transformer ensures the isolation between the power and the control and between the 2 outputs.

ARCTI CP4 – 10kV insulation

The ARCTI-CP3 board enables to transmit control pulses to a high power Thyristor.
A pulse transformer insures the 10kV insulation between the power and the control command.
The low leakage inductor of the transformer makes it possible to get a di/dt compatible with most of high power Thyristors.
We can use benefits of the product Ut of the pulse transformer due to the top value of current on the primary of the transformer.

ARCAP 50 – Phase angle thyristor control module

The ARCAP-50 is a universal phase angle control module. It enables to drive up to 2 thyristors and is suitable for all types of assemblies: rectifiers, power controllers or switch gates, one, two or three-phase. No configuration needed. The synchronization is automatically done on the input voltage of the converter. There is thus no need to set the phase difference or the tracking of the phase order.

  • High levels of insulation
  • Network voltage from 48Vac to 400Vac
  • Power supply from 12 to 24Vdc
  • Progressive starting
  • Up to 1A peak per output
  • 0-10V and 0-20mA control
FART 4 – Trigger for switch gates

The FART4 module enables to trigger switch gates (2 head-to-foot thyristors) from a 0-10V or 0-20mA control command.

  • Insulation : 3500Vac
  • Input 0-10V and 0-20mA
  • Detection of zero-crossing
  • State display
  • Standard housing
