Jefferson Electric Buck-Boost Transformers


Buck-boost transformers from Jefferson Electric are designed to maximize the performance and life of electrical equipment, such as air conditioners, heating elements, 277-volt lighting systems, and in motors applications. Also called an isolation transformer, typical use is to power loads with specific voltage requirements which differ from the available line voltage.

Jefferson Electric 60Hz single-phase buck-boost transformers, with 50VA to 2kVA ratings, are encapsulated with electrical-grade resin, featuring high-quality electrical steel cores. The NEMA 3R-rated enclosures are heat-cured with an ASA-61 gray powder coat finish and have slotted mounting holes for quick and easy mounting.

A buck-boost transformer can have two main applications. When connected as an auto-transformer, you can buck (lower) or boost (raise) available line voltage anywhere from five to 20 percent. When used as an isolation transformer, it can be used to step-down supply power to low voltage circuits at the nameplate rating listed.

Pneumatic Solenoid Valve Cables and Connectors


The pneumatics product line now includes several high-quality connectors and cables designed for most popular pneumatic solenoid air valves and sensors.

Three-wire connector cables are available in five pin spacing formats (8mm to 18mm); a four-wire transmitter cable is also available in the 8mm format. Connector styles include DIN 43650 standard forms A, B and C; two DIN style industrial forms (B and C) are also offered. The 24V or 110V AC/DC models feature built-in surge suppression and yellow LED indicator and are rated for connecting with electronics. The 230V AC/DC models are rated for straight-wired products.

Select connectors are field-wireable; all connector styles are available with three and five-meter PVC jacketed cables. Because the connectors are not polarity sensitive, users follow solenoid, sensor, or other devices wiring diagrams for proper connection.
