Abstract: A power conditioning circuit includes at least one power storage device having electrodes coupled for receiving power from a DC power source. At least one active current limit (ACL) circuit coupled to the electrodes of the power storage device is for limiting a maximum power output from the power storage device under fault conditions. A DC-to-DC converter has its inputs coupled to the ACL circuit. At least one crowbar circuit has a first terminal and a second terminal and a shorting device coupled to an output of the DC-to-DC converter for providing output terminals for the power conditioning circuit.

Abstract: A monitor can be installed in the terminal block having a monitor access opening. The installed monitor allows for current measurement without having to disconnect a wire from the terminal block. Similar monitors can measure voltage, detect ground loops, and provide continuous readings of circuit parameters. Embodiments can positively hold probe tips, transmit data over wires, or transmit data wirelessly. Make-before-break monitors allow parameters to be measured without ever breaking the monitored circuit. Break-before-make monitors allow the monitored circuit to be interrupted and then reconnected with a monitor in place.
