"Classic" Plate & Filament Enclosed Power Transformers

Path: Home > Transformer Index > Power > "Classic" H.V. - Enclosed - Chassis Mount

NOTE: A production "running change" has been made to the primary winding
- effective with August 2009 production (see below)

Key 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.
• Class A insulation (105 degrees C).
• Hi-Pot test of 2,000V RMS.
• Conservative designs - CSA certified (# LR3902).

Note: See our PDF Design Guide for rectifier use suggestions.

NOTE - Running Change to Primary Winding:

Due to customer suggestions we have added additional windings and a tap to our "200" series primaries. This will affect all production after August 2009.

CHOICE #1

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

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 above schematic).
