Manufacturing Since 1975.
Online Power has been providing critical power protection equipment and backup power supply systems since 1975. Our mission hasn't changed: help engineers, facilities managers, and OEM partners find the right power solution for their specific application.
We design, engineer, and manufacture every product at our Los Angeles facility — from compact emergency lighting inverters to megawatt-class custom OEM power systems. As a manufacturer, we offer what distributors can't: direct engineering support from the people who signed the drawings and wrote the firmware.
Our commitment to quality earned us ISO 9001 certification in 1996, and we've maintained it continuously since. Every product is UL listed and tested to meet or exceed NFPA, NEC, and other applicable safety standards.
