The Power Zero is a renewed high-quality power module standard based on the ACSP7. It offers extremely accurate measurements across the entire current and voltage operating range. is the first company to introduce a non-invasive Hall-effect current sensor for UAV/Robotics application and high precision voltage dividing circuit for consistent and reliable measurements.

Compared to the ACSP7, the .5v offset is removed and the current sensing is compared with a dedicated power reference. The integrated electrolytic capacitor reduces voltage spikes which result from longer input cable lengths and higher voltage batteries.


  • Dual internal power supply to improve the stability of the Hall-sensing.


  • 50.4v 12s lipo
  • 90 Amps Continuous - 100 Amps (Burst) Max Current Sensing
  • 5.3v / 2 Amps

Default Settings:

  • Voltage Sensing
    • 0.06534 Volts per Battery 1 Volt or
    • 15.30 Battery Volts per Volt output
  • Current Sensing
    • 0.02976 Volts per Battery 1 Amp or
    • 33.594 Battery Amps per Volt output

Important! These default values must be calibrated for your airframe within the first few flights. Keep a safe margin of battery capacity until calibrated and confirmed.
