Easy-to-use DC power analyser 4 - 60V 0 - 100A for measuring power flow in a low voltage circuit such as the flow - in Watts - and the cumulative rate of flow - in Watt-hours - from a solar panel or a DC wind generator into a battery. Simple andpositive/-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 Watts 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 peak current in Amps peak power in Watts Voltage minimum (dip) over monitoring period Low in-circuit resistance just 0.001 Ohms negligible 7mA circuit load. Dimensions 84 x 50 x 20mm (L x W x D) Note: Due to the light and screen setting difference, the item's color may be slightly different from the pictures. Please allow slight dimension difference due to different manual measurement. Sold by-Dadangjia
