200A high precision power analyzer designed to conveniently measure voltage, current, power, discharge capacity, and discharge time for aircraft applications. Suitable for multi-aircraft force effect calculations. Current range: 0–200A, continuous current 50A, resolution 0.01A. Operating voltage: 4.8–60V (a separate 12V power supply is required when test voltage is below 5V), resolution 0.01V. Energy measurement: 0–6554Wh, resolution 0.01Wh. This watt meter helps determine battery capacity via current readings, discharge time via continuous current, and assess battery internal resistance through maximum instantaneous current to help protect circuits. The power analyzer verifies adequate operating voltage under load, helping prevent damage to batteries, motor controllers, motors, wiring, and connectors. It can be used to verify proper battery charger operation by connecting your battery and charger directly. Set cut-off voltage and check battery capacity. Monitor receiver and actual operating current to evaluate components such as UBECs. Features a backlit LCD screen for clear visibility in various lighting conditions, including direct sunlight. Includes plug-in auxiliary battery support and a ventilation hole design to dissipate internal heat efficiently. Constructed with high-quality tin-copper core materials for strong load capacity and low resistance. Color: Black Material: Plastic Package Contents: 1 x Power Analyzer Note: Other items not included. Note: Lighting and display differences may cause slight color variations between the image and the actual product. Measurement error allowance: ±1–3 cm.
