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!
