Description The item is a professional and practical RC helicopter Watt Meter, which is an excellent addition to your RC hobby, DC circuits, Solar system, Boat/RV & Battery Backup systems! It isn't just a watt meter, and it is also All-In-One Meter, i.e. A power meter, a volt meter, an amp-hour meter, ammeter and energy meter. Everything all in one unit! This is the perfect troubleshooting tool. This all-in-one watt meter is indispensable for analyzing, testing and troubleshooting any DIY DC power project. Features - Color: mainly blue.- Material: durable aluminum alloy.- Size: (approx.) 8.5cm x 5cm x 2cm.- and Digital LCD Watt Meter DC 60V 100A RC Balance Voltage Battery Power Analyzer Checker.- Digital LCD screen gives clear crisp number readings.- Handles up to 100 amps intermittently and 50 amps continuous duty.- Connecting load end to the battery provides real-time battery charging reading.- Handles 0 to 60 volts. Works on 12, 24, 36, and 48 volt battery bank systems.- Extremely low power consumption of 7 mA. More efficient than any LED meter.- Measure energy(wh), charge(ah), power(w),current(A) and voltage(V).- Accurate & precise 0.01 A cuurrent and 0.01 V voltage resolutions.- Measures peak Amps, peak Watts(except for Doc Wattson) and Voltage minimum(sag).- Rugged- handles 50A continuous and 100 A peak at 60V. 14a ga., super fine stranded, high temperature, silicone rubber insulated wire.- Acts like a wire so doesn't affect model's performance. Precision Alu-Chrom current sensing resistor, with only 0.001 Ohms resistance and circuitry that draws only 7 mA.- Uses DSP to increase ADC resolution and differentiate measurement amplifiers to increase noise immunity.8MIPS micro-controller Specifications - Voltage: 0-60V, Resolution:0.01V.- Current: 0-100A peak, Resolution: 0.01A.- Power: 0-6554W, Resolution: 0.1W.- Charge:0-65Ah, Resolution:0.001Ah.- Energy:0-6554Wh, Resolution: 0.1 Wh.- Measurement Update period:400mS.- Signal Sampling Rate: sample/s.- Data Queue Sequence time: 2 seconds.- In Circuit Resistance: 0.001 Ohms.- Operation Current: 7mA.Packing list: 1 * RC Helicopter Digital LCD Watt Meter DC 60V 100A RC Balance Voltage Battery Power Analyzer Checker (Blue)
