TYPE TPOA - OPEN TYPE THREE PHASE AUTO

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.
