  • Power monitor with indicators
    Patent number: 6584418
    Abstract: A device for monitoring power conditions in the power leads of a communication network or power distribution bus includes a microprocessor 54 which measures the voltage on the power leads and computers a filtered bus voltage, Vbus, and a time-averaged bus voltage, Vave. From these, the microprocessor determines whether overvoltage, undervoltage or ripple conditions exist to actuate associated visual indicator intermittently (LEDs 57, 58, 59), or surge, brownout or transient conditions to actuate the associated indicators (LEDs 57, 58, 59) constantly for their associated slot times in a display cycle. The device may be in the form of a compatible terminator or a Tee for the network or power bus.
    Type: Grant
