Size: 146 VA
Dual Primary: 115 VAC, 125 VAC, 60 Hz.
A.C. High Voltage Secondary RMS: 600V.C.T. @ 230mA
Filament Winding #1 5 V C.T. @ 3 A
Filament Winding #2 6.3 V C.T. @ 5 A


  • Enclosed, 4 hole, chassis mount.
  • Minimum 6" long leads.
  • Units can be run full wave bridge or full wave C.T.
  • Class A insulation (105 degrees C).
  • Hi-Pot test of 2,000V RMS.
  • Conservative designs - CSA certified (209651).
  • NOTE: A production "running change" has been made to the primary winding - effective with August 2009 production.

Choice #1 (115 VAC Input): For those customers who need the 115V input - nothing has changed - simply use the White & Gray wires and tape the Black wire (see above schematic). Choice #2 (125 VAC Input): For those customers who are seeing too high a secondary voltage due to higher primary line voltages (roughly 125V input) - use the White & Black wire and tape the gray wire Caution: NEVER connect power to BOTH the GRAY & BLACK wire - instantaneous destruction of the transformer will result!

5.00 out of 5 based on 1 reviews

transformer was easy to install and connect to existing wiring. data on box was easy to follow. Works great, and stays cool. I selected this transformer as it was larger than the old one which burned out (was undersized)

Shipping. I do not know why this was double boxed. Was it due to weight? It is not a fragile item.
