200A high precision power analyzer designed for measuring voltage, current, power, discharge capacity, and discharge time for aircraft applications, including multi-axis drones. Current measurement range: 0-200A, with continuous current support up to 50A and a resolution of 0.01A. Operating voltage range: 4.8-60V (a separate 12V power supply is required when testing below 5V). Voltage resolution: 0.01V. Energy measurement range: 0-6554Wh, with a resolution of 0.01Wh. Helps assess battery capacity, discharge duration, and maximum instantaneous current for circuit protection. This watt meter power analyzer allows verification of operating voltage under load, helping prevent damage from peak currents to batteries, motor controllers, motors, wiring, and connectors. It can be used to verify battery charger performance by connecting the battery and charger directly. Features include programmable cutoff voltage setting and battery capacity checking. Enables detection of receiver and actual operating current to evaluate components such as UBECs. Equipped with a backlit LCD screen for clear visibility in various lighting conditions, including direct sunlight. Designed with a plug-in auxiliary battery interface and ventilation holes to enhance heat dissipation. Constructed with high-quality tin-copper core materials for low resistance and strong load handling capability. Color: Black Material: Plastic Package Contents: 1 x Power Detection Unit Note: The package includes only the items listed above. Light reflection and display differences may cause slight variations between the product color in images and the actual item. Measurement error allowance: +/- 1-3cm.
