Semikron SKPC100Z-440, Thyristor Trigger Module

SCR trigger modules for use in zero voltage (SKPC 100Z), or instantaneous (SKPC 100) applications. Uses a hard firing technique to eliminate the need for an external transformer.

Triggers SCRs in dc bridge configurations
Polarised Faston connectors
Mounting centres identical to SCR modules

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.
