 Superior quality and designHPS 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, they maximize inrush capability and output voltage regulation when electromagnetic devices are initially energized.
- 50/60 Hertz, 600V class, machine tool rated control transformers
- VA range from 50 VA up to 1000 VA
- Hammond power transformers use Mylar, Nomex and other high-quality insulating materials used to electrically insulate turn-to-turn windings, layer-to-layer windings, primary-to- secondary windings and ground.
- 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.
- Superior insulation systems plus high quality silicon steel laminations, provide optimum performance and reliability.
- 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.
- Heavy steel mounting feet are welded to the core, providing maximum strength and low noise in a compact design.
