Description: Product Name: Ammeter Power Module Plug: XT60 Plug/T Plug Maximum Input Voltage: 25V Maximum Measurable Current: 90A Function: Used to detect battery voltage and battery current. The flight control board receives these two signals, calculates the remaining battery power, and estimates the remaining flight time. In addition, this module also has a BEC function, which can output 5.3V DC and a maximum continuous current of 3A to provide a stable power supply for the flight control board. In addition, the connectors of the signal line are all original Japanese connectors, not domestic connectors, so that the APM flight control board and the power module are reliably connected. Feature: The maximum input voltage is 25V, and the maximum measurable current is 90A, which enables the control board to monitor the battery power and voltage. Note: APM flight control players should note that the flight control power supply is best supplied from the PM port. Since there is a power reverse voltage protection diode and a fuse in the flight control board circuit, this protection circuit will only work when the power is connected from the PM port. However, the negative effect is that the power will produce a 0.3~0.4V voltage drop after passing through these two components. If a normal 5V power module is used, the VCC voltage on the APM will not reach 5V. If other loads (OSD, data transmission, receiver, etc.) are also powered directly from the APM flight control board, the VCC voltage will be lower, and it may not be possible to guarantee the normal operation of the flight control board. However, our product is designed to be 5.3V, which can perfectly provide power for APM. Package included: 1x T Plug Ammeter Power Module or 1x XT60 Ammeter Power Module
