the application discloses a power panel applied to a laser radar, which converts 24V direct current voltage provided by a 24V direct current power output module 20 into direct current or alternating current voltage required by the laser radar currently under the control of signals of corresponding driving signal receiving ports through various voltage conversion modules; in addition, the power board generates a relay control signal to drive the corresponding relay through the relay driving module 40 under the signal control of the corresponding driving signal receiving port and the power supply of the 24V dc power output module 20, so as to drive the laser radar in the current working mode.
