Hammond Transformers Model 276X (200 Series)
Classic Plate and Filament Power Transformer - 150 VA, 640V C.T. @ 172 mA, 5V C.T. @ 3 A Filament #1, 6.3V C.T. @ 5 A Filament #2
This high voltage primary transformer can be run full wave bridge or full wave C.T. These units are enclosed 4-hole chassis mount and have Class A insultation (105 C).
Features:
- Primary 115 VAC, 60 Hz.
- For "universal" primaries and/or 50/60 Hz. operation and other output voltage combinations please see Hammond’s 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).
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 schematic on Series Spec Sheet in download section).
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 on Series Spec Sheet in download section).
NOTE: Most of the "Z" mounts do not apply to choices #1 and #2 above. See their respective drawings, on the Series Spec Sheet in the download section, for available primary voltages.
CAUTION
NEVER connect power to BOTH the GRAY & BLACK wire - instantaneous destruction of the transformer will result!
