Application solution of Mingxin 150W 24V to 12V isolated waterproof DC - DC power supply in the step
In unmanned surface vessel (USV) power systems, common24V battery busA stable 12V power supply is required for the device. This is due to the long-term exposure to...Humidity, water mist, vibration, and sunlightIn complex environments, power modules must not only possessHigh efficiency and fast dynamic responseIt must also meetElectrical isolation and IP65 waterproof protectionRequire.
Mingxin Technology XDB150-24S12 It is designed specifically for harsh outdoor environments.150W 24V to 12V Isolated Waterproof DC-DC Power ModuleInput range coverage18–26VOutput12V/12.5A,supportConstant voltage/constant current charging modeIt is very suitable for step-down power supply systems for unmanned surface vessels.
1. Why must unmanned surface vessels use isolated and waterproof DC-DC power supplies?
The electrical systems of unmanned surface vessels typically include:
Main control system and navigation module
Communication equipment and image transmission system
Sensors and cameras
Servo motor, actuator
Auxiliary lighting and monitoring equipment
Most of these devices operate at 12V, while battery systems operate at 24V. Using a standard step-down module would easily lead to problems.Water vapor erosion, co-location interference, voltage fluctuationsThis caused a system malfunction.
Therefore, the following must be selected:
To ensure power supply safety and system stability.
II. Typical Power Supply Objects of XDB150-24S12 in Unmanned Surface Vessel Step-Down Systems

5. Why is an input range of 18–36V so critical?
In actual operation, the voltage of a 24V battery will fluctuate with changes in charge level.
A full charge produces approximately 36V, while a low charge produces approximately 18V.
Insufficient DC-DC input range can cause equipment to malfunction when the battery is low. The XDB150-24S12 covers the entire battery operating range, ensuring stable operation of the unmanned surface vessel under varying battery levels.
