Hammond Power Solutions Imperator Series Transformer – Product Feature

Hammond Power Solutions’ HPS Imperator Series Transformer is a molded machine tool industrial control transformer specifically designed to meet high inrush industrial applications where electromagnetic components such as relays, solenoids and magnetic motor starters are used.

With 11 standard multi primary and secondary voltage groups available (up to 600 V) and a power range from 50 VA to 1500 VA, the Imperator provides the perfect solution for any application.

The Imperator transformer features a unique terminal block design with eight terminations per side, allowing for quick and easy installation of standard secondary or option primary fuse clips. This is the simplest and most inexpensive fusing installation provided on any industrial control transformer found in the market today.

The windings and internal terminations of the Imperator are encapsulated, protecting them from moisture, dirt and other industrial airborne contaminants. Molded coil covers are custom made with a fin-shaped design to provide superior cooling properties.

The robust insulation system can withstand a 55°C temperature rise above above ambient temperatures for transformers power rated from 50 to 150 VA (130°C insulation class) and an 80°C temperature rise for transformers power rated from 250 to 1500 VA (130°C insulation class).

Overcurrent protection relies on primary and secondary fuse selection. Primary fuses correspond with the voltage and power class of the transformer; the proper overcurrent protection device provides protection up to 300 percent of the transformer’s max rated current. Secondary fuses protect up to 125 percent of the transformer’s rated current. Fuse selection is aided by tables found in the transformer’s manual.

Mounting feet are made of heavy steel and welded or bolted to the core, providing superior strength in a compact design.
