200A high precision power analyzer designed to measure voltage, current, power, discharge capacity, and discharge time for aircraft applications, including multi-axis aircraft performance evaluation. Current measurement range: 0-200A, with continuous current support up to 50A and resolution of 0.01A. Operating voltage range: 4.8-60V (a separate 12V power supply is required when test voltage is below 5V to power the meter), voltage resolution: 0.01V. Energy measurement range: 0-6554Wh, resolution 0.01Wh. Enables battery capacity estimation, discharge time calculation based on continuous current, and assessment of maximum instantaneous current for battery internal structure and circuit protection. This watt meter power analyzer helps verify adequate operating voltage under load, protecting batteries, motor controllers, motors, and wiring. It can be used to check battery charger functionality by connecting your battery and charger directly. Supports cutoff voltage setting and battery capacity testing. Allows detection of receiver and actual operating current to evaluate components such as UBEC. Features a backlit LCD screen for clear visibility in various lighting conditions, including direct sunlight. Includes plug-in auxiliary battery connector and a ventilation hole design for effective heat dissipation. Constructed with high-quality tin-copper core materials for strong load capacity and low resistance.
