The Henry Series 80 PowerClamp is a high-energy, parallel-wired surge suppressor designed to protect studio, IT and transmitter loads from damaging power line transients while keeping equipment online. It is ideal for broadcast studios, transmitter and repeater sites, A/V systems and other mission-critical facilities with low to moderate lightning exposure.
The Henry Series 80 PowerClamp uses a hybrid multi-stage design rated at 80,000 surge amps per phase, providing ample capacity to absorb severe spikes before they reach connected equipment. Fast sine-wave tracking circuitry senses the rapid rise of incoming surges and responds within approximately 1–2 nanoseconds, clamping many transients to within a few volts of the AC sine wave while leaving the normal waveform essentially untouched. Because the device is wired in parallel across the line, it introduces no series impedance or insertion loss and does not need to be sized to the connected load.
Each Henry Series 80 PowerClamp includes individually fused suppression modules on each phase, with front-panel status LEDs that show whether protection is active and fuses are intact. If a surge ever damages the suppression circuitry, the fuse design ensures that power continues to flow to the load so the station can stay on-air while the module is serviced or replaced. Models are available for common single-phase split and three-phase WYE services so engineers can match the suppressor correctly to their local electrical system.
The Henry Series 80 PowerClamp is housed in a rugged, UL-listed enclosure suitable for indoor or outdoor mounting at distribution sub-panels, service entrances or branch circuits. Simple parallel wiring and clear labeling make installation straightforward for electrical contractors or in-house engineers, and the weather-resistant housing helps ensure long-term reliability in transmitter buildings and equipment rooms.
For facilities that need robust, maintenance-free AC surge protection with very fast response and no risk of taking critical loads offline, the Henry Series 80 PowerClamp provides broadcast-grade protection in a compact, service-friendly package.[web:189][web:193] To explore more options for protecting your studio and transmitter power systems, visit the main Power Conditioning category where additional surge suppressors and AC protection products are available.
