mRo Power Zero
Background/History of the Product:
The mRo Power Zero is a renewed, high-quality power module standard based on the ACSP7. Offers extremely accurate measurements across the entire current and voltage operating range. mRo 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.
FEATURES:
- Dual internal power supply to improve the stability of the Hall-sensing.
