Description

The HE1750 TEES has been specifically designed for use on both type 170 and on NEMA controllers. Because of the high quality of this protector, it may be used as a standalone device without the use of an external line filter. If an external line filter is required, it is recommended that a HESCO/RLS line filter be used.

The HE1750 TEES (like the popular HE1800) is a multi-stage, high energy suppressor that incorporates a sophisticated, inline EMI/RFI filter. The inline filter has been designed to effectively reject random noise and spikes from 10KHz to 25MHz. The primary and secondary clamp stages are separated by an inductive network; yet work together to give clamp voltages of under 395 volts.

The HE1750 TEES also incorporates the use of warning/failure indicators. If random data base memory loss or any other transient interference is effecting the safe operation of one or more of your intersections, the HE1750 TEES surge protector will quickly and effectively eliminate the problem.
