TECHNICAL SPECIFICATIONS:
POWERCLAMP is a sophisticated surge suppression unit that offers the ultimate in transient protection

with ULTRA-LOW CLAMPING LEVELS. Its PARALLEL INSTALLATION provides these benefits:
• No chance of power interruption
• No need to match load power
• No insertion power loss
When tested to the ANSI/IEEE C62.41-1991/UL-1449 Standard

its hybrid multistage circuitry will suppress (clamp) transient surges and spikes in all modes and bi-directionally

as listed below.
Category A waveform (6kV

200amps

0.5us

100kHz): TWO (2) VOLTS of the peak of the sine wave.
Measured from the baseline at the 90º point of the power sine wave (@ WAVEFORM PEAK).
Category B ringwave (6kV

500amps

0.5us

100kHz): TEN (10) VOLTS of the peak of the sine wave.
Measured from the baseline at the 90º point of the power sine wave (@ WAVEFORM PEAK).
Category B impulse (6kV

1.2/50us

3

000 amps): THIRTY (30) VOLTS of the peak of the sine wave.
Measured from the baseline at the 90º point of the power sine wave (@ POSITIVE WAVEFORM PEAK).
