  • 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).

  • 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!
