To accommodate your complete servo system requirements, Glentek manufactures a complete line of isolation power transformers. The transformers are offered in both single phase and three phase versions. The single phase versions range from 1-2 KVA while the three phase transformers range from 3-9 KVA of continuous power. Many specialty transformers are stocked, however their specifications are not listed on this page. Please feel free to contact a Glentek Applications Engineer to assist you in making the proper transformer selection.

Isolation Power Transformers are primarily used for the following reasons:
1) They add isolation for safety purposes between the main power line and your servo system.
2) They add impedance to the line thereby reducing high frequency voltage fluctuations.
3) They reduce or transform the main line voltage to a lower, optimum level for servo systems.
