Relay Specialties, Inc. - Hammond Manufacturing - Products - Transformers - Power - High Voltage (Plate) & Filament

Primary: Universal - 100, 110, 120, 200, 220,230, 240 VAC 50/60 Hz.
- NOTE: units are designed to operate with BOTH primary windings engaged.
- See primary wiring information under resources.
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: Our 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 our 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 our 1650 series of output transformers Units can be run full wave bridge or full wave C.T.
Conservative designs - CSA certified (209651).
