Высокая точность Вт метр и анализатор электроснабжения

High precision Watt Meter and Power Analyzer SPECIFICATIONS Operates from 4.8-60 V 0 V with optional auxiliary battery. Measures 0-130 A, resolution 0.01 A; 0-60 V, resolution 0.01 V; 0-6554 W, resolution 0.1 W; 0-65 Ah, resolution 0.001 Ah; 0-6554 Wh, resolution 0.1 Wh. 16*2, backlit LCD display. Size: 85*42*25 mm, Weight: 82 g. Example use #1: Battery on SOURCE side, Motor Speed Controller(ESC) and motor on LOAD side. With the ESC on, the Watt Meter shows the current into the motor, voltage and power at the battery and accumulates the Ah and Wh while the motor is running. Exampleuse #2: with a battery charger on the SOURCE side and battery pack on the LOAD side, the Watt Meter shows the charging current into the battery, the voltage and charging power at the battery and accumulates the charge (Ah) and energy (Wh) into the battery.
