TYPE 12Z
CONTROL TRANSFORMERS
IN PRE-MOLDED CASE
FEATURES
Designed specifically for industrial control and general purpose
applications.
Epoxy encapsulated in a small pre-molded case gives superior
humidity resistance.
Provides low-noise operation of high power SCR resonant inverters.
Meets design requirements of most Sine wave inverter circuits
