200A High precision power analyzer convenient to calculate the voltage, current, power, discharge amount and discharge time of the aircraft, and calculate the force effect of the multi-axis aircraft. Current: 0-200A, continuous current 50A, resolution 0.01A. Operates from 4.8-60V (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. The current can determine the battery capacity, the continuous current can determine the discharge time, and the maximum instantaneous current can determine the internal structure of the battery to protect circuit. Watt meter power analyzer can verify sufficient operating voltage under load and prevent currents damaging battery, motor control, motors, wiring and connectors; Verify correct battery charger operation (connect your battery and charger); Set the cut-off voltage and check the battery capacity; Detect the receiver and the actual operating current to determine whether UBEC, etc. Watt meter comes with a backlit LCD screen, so you can clearly. 't worry about testing anywhere, even in direct sunlight, you can see power analyzer very clearly. Plug-in auxiliary battery, Watt meter has a venting hole design to unblock the internal heat to the outside world. Use high-quality tin-copper core, strong load capacity and low resistance. Color: black Material: plastic Package Contents: 1 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 measurement allowed error is +/- 1-3cm.
