Description

Features

  • Primary 115 VAC, 60 Hz. - except as noted
    • For "universal" primaries and/or 50/60 Hz. operation and other output voltage combinations please see our 300 Series.
  • 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). Note: Gray wire is actually BROWN on only our Part Number 278CX.

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 (see schematic).

NOTE: Most of the "Z" mounts do not apply to choices #1 and #2 above. See their respective drawings for available primary voltages.

CAUTION

NEVER connect power to BOTH the GRAY & BLACK wire - instantaneous destruction of the transformer will result!
