Semikron SKPC200-440, Thyristor Trigger Module

Provides the control signals for an ac load, half controlled B2HZ or a half controlled B2HK single-phase bridge e.g. SKCH 28/08.

Integral transformer may be connected to a separate supply allowing the load circuit to operate on a lower voltage
Output gate drive is short circuit protected
Built in uncommitted op amp for closed loop control
Screw terminals

UL 94-V0

The number of complete mains cycles during fixed repeating periods (typically 1 to 10 seconds) is varied, thus altering the duty cycle or on-/off-time ratio. Trigger pulses coincide with the zero-crossing times of the mains supply thus ensuring no RFI is produced when using resistive loads.
