In industrial automation, motor control systems, and photovoltaic tracking applications, many platforms operate on a 24V DC bus architecture, while subsystems such as BLDC motor drivers, servo controllers, motion control boards, encoder interfaces, and solar tracker motors require stable 12V DC auxiliary power.
In high-power motor environments, voltage fluctuations, surge transients, electromagnetic interference (EMI), and temperature variations can affect system stability. Therefore, selecting a high-reliability isolated DC-DC converter with low ripple noise and strong environmental protection capability is essential.
The MINGZINC MDD150-24S12 is a 150W isolated 24V to 12V IP65 waterproof DC-DC converter specifically designed for motor drive systems and photovoltaic solar tracking applications. It features a fully sealed aluminum alloy housing, wide input voltage range, high efficiency, strong EMI resistance, fast dynamic response, and multiple protection mechanisms.
It is ideal for powering:
BLDC motor drivers
servo controllers
stepper motor control boards
motion control modules
solar tracking drive motors
Why Motor Drive Systems Require an Isolated 24V to 12V DC-DC Converter
Typical motor control architectures include:
24V DC bus → 12V auxiliary power system
The 12V subsystem supports:
BLDC motor drivers
servo motor controllers

Motor startup, braking, and load switching generate high surge voltages and EMI noise. If non-isolated converters are used, these disturbances may directly affect control electronics, leading to:
motor instability
communication interruption
controller malfunction
hardware damage
Therefore, motor drive systems should use:
isolated 24V to 12V DC-DC converters for stable and protected auxiliary power conversion
