Digital LCD screen provides clear and precise number readings. Supports up to 100 amps intermittently and 50 amps continuously. Connecting the load end to the battery enables real-time battery charging monitoring. Compatible with 0 to 60 volts. Works with 12, 24, 36, and 48 volt battery bank systems. Features extremely low power consumption of 7 mA. More efficient than standard LED meters. Measures energy (Wh), charge (Ah), power (W), current (A), and voltage (V). Accurate and precise with 0.01 A current resolution and 0.01 V voltage resolution. Measures amps, watts, voltage minimum (sag), and continuous current. Built to handle 50 A continuous and 100 A at 60 V. Functions as a wire, minimizing impact on system performance. Includes precision Alu-Chrom current sensing resistor with 0.001 Ohms resistance. Circuitry draws only 36 mA. Utilizes enhanced ADC resolution and differential measurement amplifiers for improved noise immunity. Voltage range: 060 V, 0.01 V resolution. Current range: 0100 A, 0.01 A resolution. Power range: 06554 W, 0.1 W resolution. Charge range: 065 Ah, 0.001 Ah resolution. Energy range: 06554 Wh, 0.1 Wh resolution.
