Key Features:

These transformers are fully encapsulated in a high grade black molded case with a UL94V-O rating.
They are intended mainly for thyristor / triac triggering applications.
All units are voltage proof tested between windings at 2,500V RMS for 1 minute, for a working voltage rating maximum of 440V RMS.
