The ACW is a wireless transmitter, controller and display. It can be powered by either current transformers or potential transformers in existing power line installations. The patent-pending technique of the device uses the signal (voltage and/or current) to power the RMS-DC converter and wireless transceiver for volts, amps, hertz or watts (or all four) that operate from 315 to 928 megahertz. The receiver can be powered from 5 to 32 VDC or 90 to 265 VAC and comes in a NEMA 4X case. Industrial, mil-spec or nuclear grades are available. 902 to 928 megahertz spread spectrum is for U.S. applications; 315 to 870 megahertz is for foreign installations.
