50-2000VA Single Primary and Secondary

The Triad Autotransformers Series is designed as a single-winding transformer in which the primary coil is a fraction of the entire winding for voltage step-up or the secondary coil is a fraction of the entire winding for voltage step-down. (read more)

AFP Transformers Motor Starting Autotransformers and Reactors are copper wound products and are available in NEMA Medium as well as Heavy Duty ratings. These Autotransformers or reactors are available for low and medium voltage applications with standard taps at 50, 65 and 80%. Size ratings range from 100 HP through 8000 HP for either 60 or 50 Hz use. (read more)

Harmony™ Series isolation transformers and autotransformers combine very low zero sequence impedance outputs with phase shifting for effective harmonic mitigation. Designed to replace standard or k-rated transformers especially when servicing single phase (120V L-N) non-linear loads, such as personal computers and other power electronic equipment. (read more)

A 3-phase, low zero sequence impedance autotransformer, which when connected near to and in parallel with the harmonic generating non-linear loads (usually connected at the distribution panel), provides an alternate path for 3rd, 9th, & 15th current harmonics (triplens) which the loads create. Patented Field Adjustable Impedance (FAI) feature allows for adjustment of NCE™ zero sequenc... (read more)

Single-Phase Transformers feature control and disconnecting transformers, autotransformers, and windings in copper and aluminum. (read more)

APC's Modular Three-Phase PDU brings right-sized scalability and flexibility down to the rack level in the first ever fully modular PDU. Featuring hot-swappable modular circuit breakers, it allows facilities and data center managers to add and replace circuit breakers, cordset and branch current monitoring without disruption to other circuits or critical applications.

The ICT series by Signal is designed to support isolation and buck boost severe duty applications. Constructed with epoxy encapsulation in a Nema 3R compliant steel case. Incorporating Class H UL 1446 insulation systems with top or side mounting for easy access.Also available with optional Nema cord set and outlet. Custom versions available (read more)

Buck-Boost transformers are single phase, four winding transformers designed for two purposes. The first purpose is as a low voltage isolation transformer for use on 12, 16, 24, 32, or 48 colt circuits. When used as low voltage transformers, Buck-Boost transformers have capacities of .050 kVA to 5.0 kVA. Their second, and more important use, is as a "Buck-Boost" transformer. (read more)

Many commercial and industrial applications have requirements that are not generally found in standard products or necessitate costly "work-around" solutions. UST's line of voltage regulators and power conditioners can be readily customized for your particular needs. Common customization features include:

• Adjustable output voltage
• On-line maintenance bypass
