Overview

The Hammond Power PH75MLI-FK is a machine tool rated molded industrial control transformer from the HPS Imperator™ series, engineered for reliable power conversion in demanding industrial control circuits. This 75 VA transformer delivers precise voltage regulation for electromagnetic components such as relays, solenoids, and magnetic motor starters, handling high inrush currents typical in machine tool applications. Primary voltage flexibility is provided with selectable inputs of 460V, 230V, or 208V, accommodating diverse power system requirements. Primary and secondary fuse clips are included, enabling straightforward integration of protective fuses to safeguard the transformer and downstream equipment. Constructed with copper wound coils and a welded E-core, the PH75MLI-FK features encapsulated coils encased in a custom injection molded cover for enhanced durability and dielectric strength. The transformer operates at a 55°C rise with a 105°C insulation system, meeting NEMA ST-1 and applicable UL/CSA standards. Standard SEMS washers are supplied for secure mounting, and terminal block connection numbers are molded into secondary covers for easy identification. Ideal for machine tool control panels, industrial automation systems, and manufacturing environments where stable, isolated power is critical. The compact design and bolt-on mounting brackets simplify installation in control enclosures, while the encapsulated construction ensures reliable performance in harsh industrial conditions.
