Mauch PL050 50A Power Sensor Board

The Mauch PL050 is a high-precision, standalone power sensor board designed for UAVs, multirotors, and fixed-wing aircraft running Pixhawk or other ArduPilot-based flight controllers. It provides highly accurate battery monitoring and telemetry, measuring continuous currents up to 50A without the thermal drift or voltage drop common in basic integrated power modules.

Key features

• Precision continuous current and voltage sensing for reliable battery capacity tracking.
• Native analog output compatible with Pixhawk, Cube, and standard ArduPilot/PX4 ADC inputs.
• Individually tested at the factory, shipping with specific, pre-calibrated current and voltage multiplier values for exact software setup.
• Supplied with 2 x 10 cm 12AWG leads fitted for the main battery current path.

Specifications

• Maximum continuous current: 50A
• Current sensor: Allegro ACS758-050U Hall-effect
• Voltage range: up to 14S (60 V) with the solder bridge open, up to 7S (30 V) with it closed
• Connector: Molex CLIK-Mate 1.25 mm 4-pin; connects directly to Mauch Premium-Line BECs or the Sensor Hub X2-V2
• Leads: 2 x 10 cm 12AWG
• Size and weight: 27.5 x 19.5 x 10.5 mm, 17 g bare; 43.5 x 23 x 15 mm, 22 g in the carbon enclosure (both with leads)
• Output signal: Analog (3.3V ADC compatible)
• Supported firmware/hardware: ArduPilot, PX4, Pixhawk, Cube

Note: The PL050 is a dedicated telemetry sensor board and does not feature a built-in 5V voltage regulator. It must be paired with a Mauch PL-BEC or an independent step-down regulator to safely power your flight controller and 5V peripherals.
