HE1800 LED

For more details call:


The HE1800 LED is an updated version of the popular HE1800 surge protector. The new version incorporates thermally protected MOVs and a power on and failure status LED indicator. The standard warranty is for 5 years.

The HE1800 LED incorporates a sophisticated, inline EMI/RFI filter. The inline filter has been designed to effectively reject random noise and spikes from 10KHz to 205 MHz. The unit is capable of protecting sensitive equipment from surge usp to 44kA. Modes of protection include: L-N, L-G, and N-G.

If random data base memory loss or any other transient interference is effecting the safe operation of one or more of your intersections, the HE1800 LED surge protector will quickly and effectively eliminate the problem.
