All-in-One DC Power Meter Ideal for DC circuits, solar systems, boat/RV, and battery backup systems! This is more than just a wattmeter – it's a power meter, voltmeter, amp-hour meter, ammeter, and energy meter all in one. The perfect troubleshooting tool for analyzing, testing, and debugging any DIY DC power project. Features: - Brand new and high quality - Digital LCD display for clear readings - Handles up to 100A intermittent and 50A continuous operation - Real-time battery charging readings when connected to the load end of the battery - Operates from 0 to 60 volts, suitable for 12V, 24V, 36V, and 48V battery bank systems - Extremely low power consumption (7mA), more efficient than LED meters - Measures energy (Wh), charge (Ah), power (W), current (A), and voltage (V) - Accurate readings with 0.01A current and 0.01V voltage resolution - Measures peak Amps, peak Watts, and lowest voltage (sag) - Robust design handles 50A continuous and 100A peak at 60V - Functions as a wire, minimally impacting model performance - Precision Alu-Chrom current sensing resistor (0.001 Ohms) - Utilizes DSP for enhanced ADC resolution and differential amplifiers for improved noise immunity Specifications: - Color: Blue - Voltage: 0-4V-60V (0.01V resolution) - Current: 0-100A peak (0.01A resolution) - Power: 0-6554W (0.1W resolution) - Charge: 0-65Ah (0.001Ah resolution) - Energy: 0-6554Wh (0.1Wh resolution) - Update Period: 400mS - Sampling Frequency: samples/s - Data Queue Time: 2 seconds - In-circuit Resistance: 0.001 Ohm - Operating Current: 7mA - Size: 8.3cm x 4.7cm x 2cm (3.27" x 1.85" x 0.79") Package Includes: - 1 x Watt Meter - 1 x User Manual
