International Series of 100 VA Power Transformers
Safety agency approvals include VDE 0805 (EN 60950), UL #1950, UL #1446, UL 1585 Class II & III, CSA 22.2 #66 - 1988 General Purpose, and IEC #950.
The design features shrouded primaries and a 3-flange bobbin construction which requires no electrostatic shield. Two distinct, separately isolated windings for each primary and secondary assure HIPOT capability of 4500 VRMS between these primary and secondary windings.
All Prem standard transformers are 100% final tested for induced voltage (shorted turns), exciting current, open current voltage (turns ratio), polarity (phasing), and dielectric strength.
