Sine Control PowerClamp


Series 1

POWERCLAMP is installed at the main electrical panel, IN PARALLEL with the electrical service.


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

The POWERCLAMP Series 1 plug-in PARALLEL TVSS duplex, fourplex and wire-in devices are ideally suited for isolating extremely sensitive electronic equipment, especially in areas where such equipment is not on a dedicated line. Series 1 units are rated at 20,000 surge amps per phase, and will attenuate transients generated by office copiers, computer printers, XRAY/CAT/MRI machines, and similar heavy-duty industrial equipment. POWERCLAMP Series 1 will prevent transients generated by such equipment from affecting other electronic equipment, as well as protect the equipment plugged into it. The Series 1 fourplex (with two duplex outlets) is ideal in these environments, as each pair of receptacles is isolated from the other pair. Its operation is not affected by the power requirements of the load. Hospital-grade (20 amp) units are available upon special order.


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. POWERCLAMP will clamp many transients to within 2 volts of the AC waveform. All response times including sets, resets, transfers from the first stage to the second stage and back to the first stage, are within 1-2 nanoseconds. POWERCLAMP units are designed to operate at up to 120% of the normal line voltage.
