Plate & Filament
260 Series
Universal Primary & 50/60 Hz. Operation
Features
Universal primary with taps for 100, 120, 220 or 240 VAC, 50/60 Hz. (Except the 260A6
which is 117V, 50/60 Hz only)
Designed for preamps, low power amps, general replacement, test equipment, etc.
Economical, open frame, chassis mount - two hole (.187 dia. = G) channel bracket (figure
#1) or four hole mounting (figure #2).
Units include a Faraday shield between the primary and secondary windings. Our
electrostatic shield reduces the capacitive coupling from the primary - greatly attenuating
higher frequency current coupling to the secondaries.
Minimum 5" long leads.
For more selection check out our
300 Series
of universal plate & filament transformers.
NOTES
1. These units are designed to run with BOTH primary windings energized for maximum
efficiency (see wiring table below).
2. The Faraday shield lead - the gray wire - marked SH (shield) above, should remain
grounded to the mounting bracket & in turn to the chassis.
