Product description: The professional RC watt meter is a great addition to hobby RC, DC circuits, solar system, boat battery backup/RV systems! This is no ordinary watt meter – it is a universal meter! Power meter, voltmeter, ammeter, ammeter and energy meter. All in one device! It is an excellent tool for solving problems. This versatile watt meter is essential for analyzing, testing, and troubleshooting any DC power supply project. Characteristics: The digital LCD screen shows clear, crisp number readings. Connecting the load tip to the battery provides a real-time battery charging reading. The digital LCD screen provides clear, crisp number readings. The product ma extremely low power consumption, which is more efficient than almost any LED meter. Works like wire, so it doesn't affect model performance Supports up to 100 amps with interruptions and 50 amps in continuous mode. Connecting the load tip to the battery provides a real-time battery charging reading. Supports voltage from 0 to 60 volts. It works on 12, 24, 36 and 48 V battery systems. Extremely low power consumption 36 mA. More efficient than any LED meter. Measure energy (wh), charge (ah), power (w), current (A) and voltage (V). Accurate precise resolution of 0,01 A current and 0,01 V voltage. It measures peak amps, peak watts (except for Doc Wattson) and minimum voltage (saga). Rugged – withstands 50 A in continuous mode and 100 A in peak mode at 60 V. It works like wire, so it does not affect the performance of the model. Accuracy Alu-Chrom current detection resistor, with a resistance of only 0,001 ohms and circuits taking only 36 mA. Technical data: Colour blue Voltage:(0)V-4V-60V 0.01V (resolution).
