Transformers Trigger

PT-50 Vishay Dale Transformers Trigger, SCR Isolation FEATURES • Designed for low-cost trigger source isolation in SCR power control circuits. • Small physical size and low profile provide packaging advantages. • Designed to transfer high amplitude or long duration pulses without saturation. • Industrial and commercial applications include motor speed controls, lighting controls and heater controls. • Interchangeable. Designed for circuit board mounting using same mounting dimensions as 11Z and PT-20 models.
