Accurate and precise resolutions at 0.01A current and 0.01V voltage. Measures peak current, peak watts (excluding Wattson) and minimum voltage (sag). Rugged - Supports 50A continuous and 100A peak at 60V. Brand new and high quality. The digital LCD screen provides crisp, clear readings of numbers. It supports up to 100A intermittent and 50A continuous. Connecting the end of the load to the battery provides real-time reading of the battery charge. Supports 0 to 60 volts. Works with 12, 24, 36 and 48 V battery systems. Extremely low consumption of 7 mA. More efficient than any LED meter. Measure energy (wh), charge (ah), power (w), current (A) and voltage (V). Works like wire, so it doesn't affect model performance. Precision Alu-Chrom current sensing resistor with a resistance of only 0.001 ohms and a circuit drawing only 36 mA. Uses DSP to increase the resolution of ADCs and differential in-amps for increased noise immunity. Color: Blue Quantity: 1 pcs. Size: 85x42x25mm Please note. 1. Due to variations in monitors and lighting levels, the actual color may be slightly different from the picture. 2. Due to manual measurement, deviations may occur.
