Surge Protectors


Thomas Research Products has introduced an exciting new line of advanced yet cost-effective Surge Protectors that show when they need to be replaced. Thomas Research Products is a leading manufacturer of SSL power solutions and accessories. The EOL3-277-20KA series Surge Protectors include an LED indicator that lights up when the unit reaches end-of-life, when the capabilities of the surge protector have been exceeded. The indicator also flashes at "power-up" to confirm that the LED is functioning. In-line fusing shuts down the LED luminaire to protect it until the Surge Protector is replaced. These features not only offer advanced protection for the luminaire, they make it easier for maintenance crews to diagnose issues. 

Two models are available. One includes a local LED indicator on the unit, while one is designed to operate a remote indicator that can be mounted elsewhere on the luminaire. A remote LED indicator is available with 18" leads. These surge protectors are designed to be utilized for luminaires on electrical mains up to 277V. The compact devices are rated to protect from surges up 20,000 amps and are UL1449 Recognized components. The EOL3 is also CE certified. TRP's popular Surge Protectors provide an extra level protection for LED luminaires from dangerous power line transients in commercial applications. They also protect fluorescent and HID luminaires with electronic ballasts. Avoid costly problems in 24/7 outdoor applications, including street lighting, big-box retail, warehouses, parking garages, and transportation facilities. Surge protectors for CCTV systems are also offered. The new EOL series will be available at the end of 2Q 2014
