Features:

• Primary: Universal - 100, 110, 120, 200, 220,230, 240 VAC 50/60 Hz.
• Units are designed to operate with BOTH primary windings engaged.
• Bias Tap: 50 VAC tap from high voltage secondary C.T.
• 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.
• The 300 series is an upgrade from Hammonds entire 200 Series range of units.
• 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).
• For a more economical, open frame, universal primary check out Hammond’s 260 Series.
