Plate & Filament-Open Frame (260 Series)

• Universal primary with taps for 100, 120, 220 or 240 VAC, 50/60 Hz.
• 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.

Schematic Data

 

 

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.
