Hipotronics® 3 Phase, Dry Type Auto-Transformer. Hipontronics P/N: HHT-7352. Axcelis P/N: 2400155. There is a clearance hole for a 1-1/4" liquid-tight conduit fitting on the left side of the autotransformers enclosure. There is a second clearance hole for a straight Hubbell F-4 cord grip for a 6/5 SO cord on the right side (clearance hole for a 1" NPT thread).

Transformer Materials:
• Conductors:  Insulated copper
• Layer  Insulation: Nomex™

Removed from Wilcox transmitters, these 350 watt modulation transformers are ready for a second life. They operated plate to plate on a pair of class B, 813 valves to modulate a single 250TL RF amp. This is an auto-transformer with multiple series windings. Call for details. 5-1/4" x 6-1/4" x 7-1/2" high, including insulators. We will include a copy of the Wilcox circuit in which the transformer was used.

Primary: 12v AC, 3 Phase, 60 Hz
Secondary 1: 145v AC C.T. @ 0.5 amps
Secondary 2: 5.8v AC @ 10 amps

3 Phase to Single Phase Transformer. Hermetically sealed. 4 corner post mounting. Turret terminals on bottom. 3-1/4" x 3-5/8" x 4"H.
