Henry Engineering Series 80 PowerClamp – Transient Voltage Surge Suppressor (TVSS)

Product Description

The Henry Engineering PowerClamp 80 – Surge Suppressor is a professional transient-voltage suppression unit engineered to safeguard critical broadcast and studio equipment. Designed specifically for continuous use in technical facilities, it combines ultra-fast surge clamping, hybrid noise filtration, and rugged electrical construction to guarantee uninterrupted, clean AC power delivery.

Using Henry Engineering’s proven PowerClamp technology, the 80-series module reacts to electrical surges in less than one nanosecond, instantly diverting excess energy away from connected devices. It provides full protection on line-to-neutral, line-to-ground, and neutral-to-ground paths, eliminating the risk of damage from lightning strikes, switching transients, and power-grid anomalies.

The PowerClamp 80 incorporates precision noise-filtering networks that suppress electromagnetic and radio-frequency interference, preventing audio hum, digital glitches, and signal dropouts. Its heavy-duty metal enclosure ensures excellent thermal performance and long-term reliability, even in high-temperature transmitter environments.

Front-panel LED indicators display active protection and ground integrity status, allowing engineers to verify system health at a glance. The unit automatically resets after transient events, maintaining continuous power flow without operator intervention. Designed for 24/7 broadcast operation, it is equally at home in on-air studios, control rooms, and transmission facilities.
