Thyristor trigger for zero-voltage switch-on of AC Resistive loads CB18-2-690V

These industrial quality trigger units may be used singly for single phase applications, in pairs for 2-leg control of 3-phase 3-wire loads, or 3 may be used for 3-leg control of 3-phase loads. Typical application is in the control of electric heating.

• Suitable for use in thyristor stacks rated up to 2000A
• Supply voltage range (3-phase) 440V to 760V
• Supply voltage range (single phase) 220V to 760V
