The maximum output current should be ≥2A (the Lidar requires a large instantaneous
current when starting, and a small starting current may cause its failure to start
normally). The output ripple noise should be <120 mVp-p and output voltage accuracy
<5%. It is recommended to use 12V/3A or 24V/2A power adapter.
The higher the power supply voltage and the stronger the discharge capacity, the more
severe the impact on the Lidar (such as powered by direct vehicle power supply without
adapters or interface boxes). Therefore, it is necessary to use high-power TVS transient
suppression diodes to protect the Lidar to avoid damage.
The line length of the Lidar power supply is 5~10 m, and the power supply voltage
needs to be over 19V. If the line length is more than 10 m, then it is recommended to
use a 220VAC adapter nearby for the power supply (DC long-distance power supply is
not recommended).
2.2 Electrical Interface
The cables from the side of the MS03 Lidar base are a 4-Pin power cord and a 12-Pin
ethernet cable. See the figures below.
