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 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.)
