Easy-to-use DC power analyser 0 - 60V 0 - 100A for measuring power flow in a low voltage circuit such as the flow - in - and the cumulative rate of flow - in Watt-hours - from a solar panel or a DC wind generator into a battery. Simple +positive/-negative (GND) two-wire input (Source) and two-wire output (Load) for series insertion into circuit. Two-line LCD - updated every 0.4 seconds - displays eight different values: Power 0 - 6554 to 0.1W resolution Current 0 - 100 Amps (max) 50A continuous to 0.01A resolution Voltage 4 - 60 Volts to 0.01V resolution Power flow rate 0 - 6554 Watt-hours (Wh) to 0.1Wh resolution Current flow rate 0 - 65 Amp-hours (Ah) to 0.001Ah resolution current in Amps power in Voltage minimum (dip) over monitoring period Low in-circuit resistance just 0.001 Ohms negligible 7mA circuit load.
