General Purpose Distribution Transformers - 50 VA to 1000 kVA
L3 Power Magnetics' single and three-phase general purpose distribution transformers are rated for 600 volts and below. They are either ventilated or totally enclosed, and are available in standard ratings from 50 VA up to 1000 kVA. Shielded distribution transformers are available, providing an electrostatic shield between the primary and secondary windings with the shield grounded, which shunts most noise and transients to the ground so they do not pass through to the secondary winding.
Encapsulated General Purpose Transformers - Single Phase ratings 0.05 kVA to 37.5kVA or Three-Phase Ratings 2 kVA to 1000 kVA
L3 Power Magnetics' single-and three-phase general purpose encapsulated transformers are rated for 600 volts and below. Encapsulated transformers are encased in electrical grade silica and epoxy, and totally enclosed in a heavy duty NEMA enclosure. All leads are brought out to a separate termination compartment. Encapsulated transformers are available in single-phase ratings from 0.05 kVA up to 37.5 kVA and three phase ratings from 2kVA up to 1000 kVA. Electrostatic shields between the primary and secondary windings are standard on single-phase units above 0.50 kVA and optional on most others.
Non-Linear (K-factor) Distribution Transformers
Computers, fax machines, copiers, printers, cash registers, UPS's and solid-state ballasts in offices and industrial plants often require switching power supplies or rectifier circuits to power them. These devices contribute to the distortion of the current waveform and the generation of harmonics. L3 Power Magnetics' K-factor transformers are general purpose transformers that are designed to mitigate the harmonic distortion associated with these loads.
Energy Efficient (TP1) Distribution Transformers
L3 Power Magnetics energy efficient, dry type, general purpose distribution transformers meet NEMA TP-1 specifications. In addition to the benefits Power Magnetics energy efficient transformers have on the environment, energy efficient transformers can realize measurable savings in operating costs, having a direct impact on the initial investment evaluated over a period of time.
Drive Isolation Transformers - up to 22 MVA
L3 Power Magnetics Drive Isolation Transformers are designed to meet the rugged demands of both AC and DC variable speed drives while providing the required voltage change. Drive Isolation Transformers are rated to match standard motor HP and voltage ratings. Standard sizes range from 5 to 600 HP. Custom ratings and voltages are available upon request.
AutoTransformers - 3 kVA to 2500 kVA
L3 Power Magnetics three phase autotransformers are available for applications where small voltage corrections are necessary in a distribution system. Autotransformers can be used as either a step-up or step-down transformer, and are available in ratings from 3 kVA to 2500 kVA.
Custom Distribution Transformers
L3 Power Magnetics custom distribution transformers are designed and constructed to meet or exceed standard general application transformers. Custom transformers can be designed either ventilated or totally enclosed to meet the special applications and requirements of your specific needs.
