    POWERCLAMP is a sophisticated surge suppression unit that provides the ultimate in transient protection with much lower clamping levels than any other TVSS device.

    POWERCLAMP Series 4 wire-in PARALLEL TVSS devices are intended for broadcast studios, computer rooms, and similar applications that have moderate exposure to lightning and other extreme transients. They are rated at 60,000 surge amps per phase and will prevent power line spikes from damaging studio equipment, computers, and other sensitive equipment. Their superior surge suppression will greatly reduce equipment failures and computer lock-ups that are caused by power line disturbances. Operation is not affected by the power requirements of the load. Each line phase is fused, with a fuse status lamp. An unlikely failure will not interrupt power to the load.

    POWERCLAMP Series 4 units should be installed at branch or sub-panels with upstream (main panel) protection. A Series 4 can also be used at the main entry panel in residential environments.

    POWERCLAMP Transient Voltage Surge Suppressor (TVSS) device is a passive, multi-staged hybrid high energy parallel device designed to react to the onset of surges with fast rise times and high amplitude ranges such as those which follow sags or other external or atmospheric induced impulses. POWERCLAMP senses the fast ramp of the transient and automatically fixes on the peak of the line voltage waveform. The unit incorporates sine wave tracking, to ‘float’ the clamping threshold with the rise and fall of the peak of the AC waveform without creating wave shape distortion. Response times are within 1-2 nanoseconds. POWERCLAMP will clamp many transients to within 2 volts of the AC waveform. Units operate at up to 120% of the normal line voltage.
