The PQ2000 Power Quality System is an easily installed power source that delivers up to 2,000,000 watts for 30 seconds, and it easily can be made mobile.
The PQ 2000 is a battery-based, energy storage and delivery system designed to mitigate the effects of factory-wide power disturbances on sensitive electronic and electrical equipment. It also might mitigate the effects of a power surge, sag or outage on a utility grid.
Rather than acting like a circuit breaker and shutting down a utility line, the PQ2000 monitors the line for voltage sags, swells or momentary interruptions. Sensing something amiss, the PQ2000 transfers the line in one four-hundredths of a second to stored battery energy. This acts as a high-power voltage source for up to 10 seconds before returning the equipment to normal power service as the momentary disturbance passes.
