Power Supply Requirements
■ Input Voltage
To ensure that the input voltage at the LiDAR's Lemo connector is 9~36 V DC, please check the specifications of the power source and the voltage
drop over cables.
We recommend using 26 AWG cables, which is the thickest wire gauge supported by the LiDAR
· Define the cable length from the power source to the LiDAR's Lemo connector as L (unit: m)
· When using 26 AWG cables, the estimated cable resistance is r = 0.3L (unit: Ω)
· Define the source voltage as U_in (V). The cable voltage drop of the LiDAR operating at 10 Hz under room temperature (23±5°C) can be
estimated:

Users may also estimate the cable voltage drop using the following lookup table.
When cable length exceeds 10 m, source voltage should be at least 24 V.
