Mingxin Technology launchedMDD150-24S12A product designed forMotor drive and photovoltaic tracking systemDesign150W 24V to 12V Isolated IP65 Waterproof DC-DC Power ModuleThe product usesFully sealed aluminum alloy heat dissipation casing,haveWide input voltage range, high efficiency, low ripple, strong anti-interference, fast dynamic response and multiple protection mechanismsEspecially suitable for12V brushless DC motor driver, servo controller, stepper motor control board, and photovoltaic tracking system motorProvides a stable power supply.

Why does a motor drive system require a 24V to 12V isolated power supply?

In a motor control system, a typical power supply architecture is as follows:

• 24V DC bus → 12V auxiliary power supply

12V is mainly used for:

• Brushless DC motor driver (BLDC Driver)

• Servo motor controller

• Stepper motor drive module

• Motion control board and encoder interface

• Motor drive unit of photovoltaic tracking system

Motor starting, braking, and sudden load changes can generate significant voltage spikes and electromagnetic interference. If a non-isolated power supply is used, these interferences can directly affect the control circuit, leading to motor malfunction, communication abnormalities, or equipment damage.

Therefore, in motor drive systems, the following is recommended:

24V to 12V Isolated DC-DC Power ModuleThis achieves electrical isolation, interference immunity, and stable power supply.
