The History of RONK ELECTRICAL INDUSTRIES:

A Tradition of Adapting to Meet Our Customer's Needs

Our History

Since 1950, RONK ELECTRICAL INDUSTRIES has been a leading manufacturer of high-quality electrical products and equipment. Originally founded as the Systems Analyzer Corporation in Nokomis, IL, RONK began by developing phase converters for the agriculture industry. The company was soon acquired and renamed RONK ELECTRICAL INDUSTRIES by LeRoy Ronk, who expanded its scope well beyond phase converters.

Today, RONK continues to operate exclusively in Nokomis, IL, where we manufacture an extensive range of products, including phase converters, power factor correction capacitors, stray voltage isolators, meter sockets with circuit breakers, double-throw switches (both metered and unmetered), transfer switches, docking stations, and outdoor equipment enclosures. Our market reach has grown beyond agriculture to serve various industries, including oil and gas, water and wastewater, utilities and electrical co-ops, healthcare, government, HVAC, irrigation, and generator systems.
