• 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 2500V RMS for 1
minute, for a working voltage rating maximum of 440V RMS.
• Transformers with three or more windings can be series connected to obtain
alternative ratios. (ie...a 1:1:1 type may be series connected by linking pins 4
& 5 in which case 3-6 are used as the primary winding to obtain a ratio of 2:1
etc.)
