Energy-Tripped Circuit Breaker Trips After a Time Interval That Varies as a Function of Sensed Load Current

Sep 7th 2011
The circuit of this circuit has three distinct parts – circuit breaking, current sensing and timing. The circuit breaking function can be any type of electronically controlled relay or solid state switch, properly sized for voltage and current ratings of the load being protected. Load current sensing is achieved via an ...

Autoranging True RMS-to-DC Converter

Sep 10th 1999
A programmable gain amplifier (LTC6910-2) and a window comparator (LTC6700-1) and some control logic creates a wide dynamic range RMS to DC converter. The comparator monitors the DC output and signals whether to increment or decrement the gain to maintain a predetermined output voltage range. Knowing the output DC voltage and ...
