Micron General Purpose Transformers

Product Description

Micron offers single and three phase general purpose transformers. Options include ventilated or enclosed designs. Micron also offers Buck-Boost transformers which provide an economical method of correcting lower or higher voltage to a voltage rating more suitable for efficient equipment operation. Thermal Devices has a Micron general purpose transformer for almost any application.

Single Phase Type 1-E

Encapsulated Type 1-E general purpose transformers are single phase, resin encapsulated designs suitable for indoor or outdoor applications. It’s totally enclosed, non-ventilated enclosure make it ideally suited for use in areas that contain dust, moisture, or corrosive fumes. Available in ratings through 25 KVA type 1-E transformers can be mounted in any position for indoor installations and in upright positions only for outdoor installations.

Three Phase Type 3-E

Encapsulated Type 3-E resin encapsulated, 3-phase transformers are available in ratings of 3-75 KVA. It’s totally enclosed non-ventilated enclosure makes the 3-E ideally suited for outdoor as well as indoor locations. Type 3-E transformers utilize the 185°C insulation system with 115°C rise. 3-E transformers 3-15 KVA are T-T connected. Units installed outdoors must be mounted in upright position.

Single Phase Type 1-V Ventilated

1-V general purpose transformers are single phase ventilated units designed primarily for indoor locations (also for outdoor for 600-volt class with the addition of weathershields). The 1-V utilizes a 220°C insulation system with 150°C rise and is available in ratings of 15-167 KVA.

Three Phase Type 3-V Ventilated

The 3-phase 3-V ventilated dry-type is available in ratings of 15-750 KVA. Its 220°C insulation system (150°C rise) is self-extinguishing. 3-V enclosures are designed for indoor locations (or outdoors for 600-volt class with addition of weathershields).

Buck-Boost Transformers

A Buck-Boost Transformer is used to provide an economical method of correcting a lower or higher voltage to a voltage rating more suitable for efficient operation of electrical equipment.

Buck-Boost Transformers are small KVA, single phase, 600-volt class insulating transformers with dual primary and dual secondary windings and are usually connected as autotransformers by utilizing one unit for single phase applications and either two or three units banked for three phase operation. They are primarily used for motor operation and should not be used for motor control circuits, to correct fluctuating line voltage or to obtain a neutral on a delta system. These applications require transformers especially designed for these specific applications.
