Transformation unit - Import export

Product Features: • A perfect match to the 1650P Series Potted Output transformers. • Enclosed in a drawn steel case, the transformer is completely potted in epoxy. • Mounting hardware included. • Primary: Universal - 100, 110, 120, 200, 220, 240 VAC 50/60 Hz. • Bias Tap: 50 VAC tap from high voltage secondary C.T. • Highpot tested: 2,000 VAC. • Faraday Copper Primary Shield: The electrostatic shield reduces the capacitive coupling from the primary - greatly attenuating higher frequency current coupling to the secondaries (shield is internally grounded to the end bell). • Windings: Concentric wound for low stray field and low noise. • Finish: Black powder paint to match the 1650P Series of potted output transformers. • Units can be run full wave bridge or full wave C.T. • c UL us recognized (E207860).

Product Features: • Primary: Universal - 100, 110, 120, 200, 220, 230, 240 VAC 50/60 Hz. • Bias Tap: 50 VAC tap from high voltage secondary C.T. (except part number 379WX - uses a separate 60VAC 0.2 Amp winding). • Highpot tested: 2,000 VAC. • Faraday Copper Primary Shield: The electrostatic shield reduces the capacitive coupling from the primary - greatly attenuating higher frequency current coupling to the secondaries (shield is internally grounded to the end bell). • Windings: Concentric wound for low stray field and low noise. • Models: This series is an upgrade from the entire 200 Series range of units PLUS 2 models designed specifically for 300B tubes (Part number 300BX) and 2A3 tubes (Part Number 302AX). • Finish: Black powder paint to match the 1650 Series of output transformers • Units can be run full wave bridge or full wave C.T. • Conservative designs - CSA certified (209651).

Product Features: • Enclosed, 4-hole mount chokes (some models also available epoxy potted in a black powder paint - drawn steel housing. Potted models mount with 1/4" - 20 hardware (included). • Tolerance of 15% on both inductance and resistance. • Inductances measured at rated D.C. current. • Minimum 8" long leads. • Units will exhibit less inductance at slightly higher currents or more at lower currents. • Perfect for high voltage power supply filtering, case matches power transformers and tube audio output transformers. • Units are vacuum impregnated with polyurethane varnish for quiet and long life operation. • Operating temperature range is -40C to 85C. • Proper Henry testing requires an LCR meter in junction with a 25A power supply that does allow for DC bias as well a higher applied AC drive voltage to meet the test specifications.
