Measures 0 to 60 volts, works on 12, 24, 36 and 48 volt battery bank systems. consuming only 7mA.Here is the All-in-one meter: a power meter, a voltmeter, an ammeter, an ammeter and an energy meter. The digital LCD display gives clear and accurate readings.Perfect troubleshooting tool: It is essential for analyzing, testing and troubleshooting any DIY DC power supply project.The professional RC power meter is a great addition to your RC hobby systems, circuits DC, solar system, boats/RVs and backup systems. Product Information: Digital LCD display gives clear and accurate readings. Handles up to 100 amps intermittent and 50 amps continuous duty. Connecting the load to the battery allows a real-time reading of the battery charge. Handles from 0 to 60 volts. Works on 12, 24, 36 and 48 volt battery bank systems. Extremely low power consumption of 7mA. More efficient than any LED meter. Measure energy (wh), charge (ah), power (w), current (A) and voltage (V). Accurate and accurate current resolutions of 0.01 A and 0.01 V. Measures for peak amps, peak watts (except Doc Wattson) and minimum voltage (sag). Heavy duty - handles 50A continuous and 100A peak at 60V. Acts like a thread so as not to affect the performance of the model. Precision Alu-Chrom current sense resistor, with resistance of only 0.001 Ohms and circuits drawing only 7 mA. Uses DSP to increase ADC resolution and differential measurement amplifiers to increase noise immunity. Specifications:Voltage: (0)V-60V 0.01V (resolution). Current: 0-200 A peak 0.01A (resolution).
