Super Isolation Transformers - single phase ratings 120 VA to 20 kVA; three phase ratings 3 kVA to 75 kVA
L3 Power Magnetics Super Isolation Transformers are shielded by a simple circuit configuration and have no moving components, providing fast response, automatic output current limiting and high reliability with complete isolation from the power line. Super isolators are ideal for noise suppression when equipment has internal voltage regulation from switching power supplies. All Power Magnetic units are available with single phase ratings from 120 VA to 20 kVA and three phase ratings from 3 kVA to 75 kVA.

Harmonic Mitigating Transformers - 15 to 1000 kVA
L3 Power Magnetics' energy-efficient harmonic mitigating transformers are specifically designed to alleviate the harmonics generated by computer equipment and other non-linear, power electronic loads. Power Magnetics harmonic mitigating transformers are available in several voltage offerings from 15 to 1000 kVA.

Dry-Type Power Transformers
L3 Power Magnetics' produces dry-type power transformers up to 22 MVA that perform in various environmental conditions and are built to meet the most rugged standards, including Military Specifications. In addition to conventional indoor applications, our dry units are deployed outdoors on drilling platforms, in network vaults and in locations where airborne contaminants could pose a risk to electrical equipment.

Medium Voltage Transformers - single phase ratings 15 kVA to 33 3kVA; three phase ratings 15 kVA to 750 kVA
L3 Power Magnetics' medium-voltage transformers are used for stepping down higher voltage incoming power to provide appropriate voltages for commercial, institutional or industrial applications. Enclosed ventilated units are suitable for indoor or outdoor applications. Single-phase units have ratings from 15 kVA to 333 kVA and three phase units have ratings from 15 kVA to 750 kVA.

Standard Power Transformers - 500kVA 1.2 kV class to 7500 kVA 15 kV class
L3 Power Magnetics' power transformers are suitable for any commercial, industrial, manufacturing or production application. Power transformers can be installed at both indoor and/or outdoor locations, where airborne contaminants pose a risk to electrical equipment. Power Magnetics power transformers are available in ratings from 500 kVA, 1.2 kV class up to 7500 kVA, 15 kV class.
