The
Pulse Type Transformers
BA to BE series. P.C. board mount, pulse encapsulated transformers
630 Series
|
640
Series |
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.)
