Features 100% Brand New High Quality. Power Meter and Power Analyzer 150/200 Amps (+2x Anderson plug). Colour: Black Dimensions: 85 x 42 x 25mm Material: rubber paint Operating voltage is 8v to 60v. Voltages down to 0v can be measured with an optional auxiliary battery (perfect for stress test batteries). Measures 0 to 150A with 0.01A resolution (50 amp connector for continuous - up to 150A for short peak bursts only). Measure 0 to 60V with 0.01V resolution Measures 0 to 6554W with 0.01W resolution Measure 0 to 65Ah with 0.001Ah resolution Measures 0 to 6554 Wh with 0.01 Wh resolution. Blue-backlit 2.4"LCD display Handles 8 to 60 volts. Available for 4, 6, 12, 24, 36 and 48 volt battery pack systems. Very low power consumption of 7 mA. More efficient than any LED meter. Digital LCD LIGHT UP screen provides clear and clear digital readout. Backlight. Handles up to 150A intermittent and 75A continuous duty (48V) Microprocessor control produces extremely precise and accurate readings. Ampere Hours (Ah) The total amount of electricity, Ah, transferred from the source to the load. Ampere Peak (Ap) The highest amperage value delivered (usually the start-up cycle of inverters, compressors, refrigerators, etc.). Amps (A) Amps delivered at this point in time. Voltage Source voltage and minimum source voltage. Suitable for measuring the voltage at the lowest charging point (such as the lowest overnight voltage of a car refrigerator battery). Power (Watts) - Peak watts, watts delivered at that point in time. The meter can be turned"to measure the amount of power
