Our transformers are setting new standards for quality – in design, manufacturing and testing. Before leaving the factory, every Midwest transformer must pass a series of rigorous tests, performed with advanced equipment, on a range of specific requirements.

Dry Type Vented

Midwest Electric Transformers
A reliable, energy-efficient design for general purpose lighting and electrical applications. Available in single-phase from 15-250kVA and three-phase from 15-1000kVA.
Midwest Electric Transformers
K Factor rated for nonlinear loads. These transformers have passed the UL K-factor testing program. Midwest offers K=4, K=13, K=20 and K=30 transformers.
Midwest Electric Transformers
The vibrations within the magnetic steel core have been greatly reduced, thus lowering the humming of the transformer to 3dB to 5dB less than NEMA/ANSI standards.
Guard I & II Noise Isolation Transformer
Guard I transformers provide common mode noise attenuation and transverse mode noise attenuation. Guard II adds an enhanced level of transverse mode noise attenuation for
Guard III Harmonic Mitigating
Guard III harmonic mitigating transformers help eliminate harmonic currents and minimize power quality problems.
Servicenter Integral Transformer
Single-phase 5-25kVA, Three-phase 15-30kVA. Brings together three quality products in one convenient, compact solution: transformer, distribution panel and circuit breakers.
Midwest Electric Transformer
A Drive Isolation Transformer (DIT) is designed to specifically handle the mechanical stresses, voltage distortions and harmonics associated with SCR applications.

Dry Type Non-Ventilated

Totally Enclosed, Non-Ventilated (TENV)
15-75kVA, Three-Phase. When dry-type transformer benefits are desired but the standard enclosure openings are unacceptable due to adverse atmospheric conditions.

Dry Type, Encapsulated, Enclosed

Dry Type Encapsulated Enclosed Single Phase Transformer
These Midwest transformers feature encapsulated core and coils in a NEMA 3R nonventilated weatherproof enclosure.
Dry Type Encapsulated Enclosed Three Phase
This Midwest transformer features encapsulated core and coils in a NEMA 3R nonventilated weatherproof enclosure.
Buck Boost Transformer
Convenient and least expensive method of matching line voltage with equipment voltage. Primary voltages: 120V, 240V, 480V. Secondary voltages: 12V, 16V, 24V, 32V, 48V.

Dry Type, Core & Coil

Machine Tool and Control Power Transformer
Terminal Board Connections. 0.05-3.0kVA, Single-Phase. Used to provide voltage to control devices in applications where regulation and minimum space are important.
Machine Tool and Control Power Transformer
Leads Out. These Midwest transformers are welded core and provide the highest quality electrical performance. Rated at 55°C rise with 40°C ambient.
