The high-precision 200A power analyzer is convenient for calculating the voltage, current, power, discharge amount, and discharge time of the aircraft, and calculating the power of multi-axis aircraft. Current: 0-200A, continuous current 50A, resolution 0.01A. Works from 4.8 to 60V (when the test voltage is lower than 5V, a separate 12V power supply is required to power the power meter), resolution 0.01V. Measures 0-6554Wh, resolution 0.01Wh. Current can determine battery capacity, continuous current can determine discharge time, and the maximum instantaneous current can determine the battery's internal structure to protect the circuit. The power meter's power analyzer can check sufficient operating voltage under load and prevent peak currents from damaging the battery, motor control, motors, wiring, and connectors; Check the battery charger's function (connect your battery and charger); Set the cutoff voltage and check battery capacity; Detect the receiver and the actual working current to determine if UBEC, etc. The power meter comes with a backlit LCD screen, so you can see more clearly. Don't worry about testing anywhere, even in direct sunlight you can see the power analyzer very clearly. Plug-in auxiliary battery, the power meter has a ventilation hole to release internal heat to the outside. Use high-quality tin-copper core, strong load capacity, and low resistance. Color: black Material: plastic Package contents: 1 x Power detection Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The allowed measurement error is +/- 1-3 cm.
