Transformers use electromagnetic induction to perform voltage conversion and provide isolation, and are available in encapsulated, ventilated/open, buck-boost, and compact control styles in various ratings and configurations. Models for indoor/outdoor service are also available.
A transformer is an electrical device for safely "stepping up" or "stepping down" voltages to meet the incoming power requirements of connected equipment. Used in nearly every power distribution system application, they can range in size from several tons to tiny devices found in compact electronic equipment. Available are:
HPS (Hammond Power Solutions) Sentinel series general-purpose ventilated transformers, available in various primary and secondary voltage configurations, feature an advanced core and coil construction that provides higher efficiency, resulting in low operating costs and more cooling savings due to lower heat emissions.
HPS drive isolation transformers are designed to meet the rugged demands of both AC and DC variable speed drives to provide required voltage changes and electrical protection. The separate primary and secondary windings provide electrical isolation between the incoming line and the VFD input.
Encapsulated distribution transformers, filled with electrical grade silica and resin compounds to protect the core from moisture and other contaminants, are available in various configurations. Units with completely enclosed NEMA 3R housings are suitable for indoor/outdoor applications.
Buck-boost transformers use voltage matching to maximize the performance and life of electrical equipment where a different voltage is required than what is available at the installation site. They are available in a wide range of primary/secondary configurations.
HPS (Hammond Power Solutions) Spartan series 1-phase open core control transformers are a practical low-cost option for high-inrush applications, such as contactors or solenoid valves, that require reliable output voltage stability. This inrush current caused by these inductive loads has no adverse effect on the transformer.
HPS (Hammond Power Solutions) Imperator series encapsulated 1-phase control transformers have enclosed cores to seal out moisture and other contaminants, specifically designed for high-inrush applications requiring reliable output voltage stability in harsh environments.
Optional primary side fuse kits for certain Imperator control transformers contain four fuse clips, four mounting screws, and instructions.
Fuse block adapter kits allow the addition of third-party primary or secondary fuse block assemblies for certain Spartan control transformers rated up to 3000VA or 30A.
