  • Publication number: 20080031751
    Abstract: A sump pump control system for monitoring and driving AC pumps that are supplied by directly either by AC utility power, or converted DC battery power. AC power is continuously monitored and the control automatically switches to DC battery supply in the case of power failure. DC battery power is converted to AC power. The control is equipped with unique pump switching circuitry allowing the pumps to be configured in parallel or staggered positions. Both pumps automatically alternate to prevent damage to pumps from humidity and corrosion that can result from remaining idle. Each pump has its own float switch to control operation. A third float switch controls both pumps in case of failure of either pump or float switch. Multiple visual and audio signals are included, displaying present power and pump conditions as well as alerting to any pump malfunction.

  • Publication number: 20080030916
    Abstract: This unit is intermittent duty, small, and light weight. Use of a thyristor(s) control reduces the unit's energy consumption through reduced AC input voltage while still producing sufficient demagnetizing power and effective demagnetizing results. This principle may be applied to ANY and ALL sizes of demagnetizing coils. With the burst control we can achieve same demagnetizing power and reduce overall power consumption of the demagnetizing coil(s) reducing size and weight of the coil(s). For this intermittent duty coil(s) the power consumption is reduced by over 40% and heating rate reduced which allows approx. 40% longer continuous running time.
