In-stock & available for expedited delivery
**See drop-down menu for full range of kVA, Input/Output voltage options.• Marcus Type TPOA three-phase auto transformers provide a quick and simple way to convert standard supply voltages to those special voltages required by small loads and fractional motors.
• These compact open-type copper transformers are Y-connected and are fitted with clearly labelled fiberglass terminal boards with solidly fixed connection studs for easy installation.
• Unlike the use of multiple unit buck-boost arrangements, there is no complicated internal wiring necessary and no conversion charts to decipher.
• As with all auto transformer installations, the loads are not isolated from the line source and caution should be exercised when there are electronics or computer controls present.
• Available in a full range of voltage combinations up to 3KVA.
