1. Why do industrial robotic vacuum cleaners need a 48V to 24V isolated power supply?

Large industrial sweeping robots typically employ the following power supply architecture:

• 48V lithium battery pack → Robot's main propulsion system

• 48V bus → 24V auxiliary system power supply

24V is mainly used for:

• Sweeping motor driver

• Rotary brush motor

• Vacuum Cleaner Control System

• Water pumps and cleaning spray systems

• LiDAR (Light Detection and Ranging)

• Visual camera and AI recognition module

• Motion controller and PLC

• Navigation and Communication Systems

• Sensors and obstacle avoidance systems

Industrial cleaning environments are often accompanied byMotor starting shock, electromagnetic interference, vibration, dust, high temperature and humidityChallenges such as these, if a conventional non-isolated power supply is used, may result in:

• Control system restart

• Sensor data anomaly

• Motor runaway

• Communication interruption

• Equipment damage

Therefore, the standard practice for industrial robotic vacuum cleaners is to adopt:

48V to 24V Isolated DC-DC Power ModuleThis achieves electrical isolation, interference immunity, and stable power supply.
