Features 100% brand new high quality. Power meter and power analyzer 150/200 A (+ 2x Anderson plug). Color: black Dimensions: 85x42x25mm Material: rubber paint Working voltage is from 8v to 60v. Voltages down to 0v can be measured with an optional auxiliary battery (ideal for test batteries). Measures from 0 to 150A with 0.01A resolution (50 amp connector for continuous - up to 150A for short peak bursts only). Measure from 0 to 60V with a resolution of 0.01V Measures from 0 to 6554W with a resolution of 0.01W Measure from 0 to 65Ah with a resolution of 0.001ah Measures from 0 to 6554Wh with a resolution of 0.01Wh. 2.4" blue backlit LCD display. Supports 8 to 60 volts. Available for 4, 6, 12, 24, 36 and 48 volt battery systems. Very low power consumption of 7 mA. More efficient than any LED meter. Digital backlit LCD screen provides crisp and clear digital readout. Backlight. Supports up to 150A intermittent and 75A continuous (48V) Microprocessor control ensures extremely precise and accurate readings. Ampere hours (Ah) - the total amount of electrical energy, Ah, transferred from the source to the load. Ampere Peak ( Ap) - the highest current value delivered (usually the starting cycle of inverters, compressors, refrigerators, etc.). Amplifiers (A) - amplifiers delivered at this point in time. Voltage - the source voltage and the minimum source voltage. Suitable for measuring voltage at the lowest charging point (e.g. lowest overnight voltage of a car refrigerator battery). Power (watts) - Watts peak, watts delivered at this point in time. The meter can be "rotated" to measure the amount of energy returned to the battery during the charging cycle. In this case, the charger (DCDC, solar, wall charger) is connected to the source and the battery is connected to the "load". Charging Cycle to Read: Ampere Hours (Ah) - Total charge delivered to the battery Ampere Peak (Ap) - Maximum power delivered to the battery (batch charging) Voltage - Spot voltage from the charger (the charger is not over or under charged) Package Included: 1 x Power Meter 1 x English User Manual Note: 1. Due to the difference of display and lighting effects, the actual color of the item may be slightly different from the color shown in the picture. Thanks! 2. Due to manual measurement, please allow 1-3mm measurement deviation.
