SNC Manufacturing introduces 18-pulse autotransformer and Gen II industrial control transformer

July 26, 2018 - SNC Manufacturing, an international manufacturer of electrical transformers, utility and communications products, will be launching an 18-pulse autotransformer and a second generation of their industrial control transformer. Both products will be released September 1.

SNC developed the 18-pulse autotransformer based on demand from OEMs. This heavy-duty multi-phase transformer, available in horsepower ratings from 50 to 500, is designed to reduce harmonic distortion for variable frequency drive applications.

The transformer, a 3-phase, 480-volt primary and 427-volt secondary, 60-Hz unit, is ETL UL 1561 certified. Features include copper windings; 180-degree Celsius or better insulation; and thermal switches that are normally closed as an added safety measure, if required. This unit offers copper busbar terminations in various sizes to meet application requirements. It’s available with or without enclosure.

The Gen II industrial control transformer, designed to meet National Electrical Manufacturers Association (NEMA) ST-1 inrush volt amp (VA) regulations, offers a completely enclosed coil and finger-safe terminals. The units feature bobbin wound construction with full current copper windings, integrally mounted terminal blocks with isolation barriers to prevent arc overs and heavy-gauge steel mounting plates with flexible mounting positions.

With units from 50VA to 5,000VA, the Gen II industrial control transformers are used in a wide range of applications where space is critical, including medical equipment, electrical vehicle battery chargers and HVAC systems.

Offered in a complete range of input and output voltages (600-volt class and below), the units are UL, cUL and CSA listed with CE agency approval available. Based on application requirements, customers can choose from three temperature classes and insulation systems adjustable by VA size:

  • 50VA to 100VA, 55-degree Celsius temperature rise, 130-degree Celsius insulation system
  • 150VA to 750VA, 80-degree Celsius temperature rise, 130-degree Celsius insulation system
  • 1,000VA to 5,000VA, 115-degree Celsius temperature rise, 180-degree Celsius insulation system
