HPS Imperator control transformers from Hammond are specifically designed for high inrush applications requiring reliable output voltage stability. Designed to meet industrial applications where electromagnetic devices such as relays, solenoids, etc. are used, these industrial power transformers maximize inrush capability and output voltage regulation when electromagnetic devices are initially energized.

Four series of compact control transformers are available:

• MQMJ Series - 480x240 VAC to 240x120 VAC Overview
  
  
• MGJ Series - 380x277x208 VAC to 240x120 VAC Overview
  
  
• PG Series - 240x120 VAC to 24x12 VAC Overview
  
  
• MLI Series - 480x240 VAC to 120x25 VAC Overview
  
  

Superior quality and design

• Hammond power transformers use Mylar, Nomex and other high-quality insulating materials. Insulation is used to electrically insulate turn-to-turn windings, layer-to-layer windings, primary-to- secondary windings and ground.
  
  
• These industrial control transformers are vacuum impregnated with VT polyester resin and oven-cured, which seals the surface and eliminates moisture. Filling the entire unit provides a strong mechanical bond and offers protection from the environment.
  
  
• This design utilizes superior insulation systems and is constructed with high quality silicon steel laminations, which provide optimum performance and reliability.
  
  
• The custom injection-molded cover, with its unique fin-shaped design, provides excellent cooling properties while protecting the coils and terminations from moisture, dirt and other industrial airborne contaminents.
  
  
• The heavy steel mounting feet are welded to the core, providing maximum strength and low noise in a compact design.
