Explore Our Industrial Power Supply Range
Different equipment requires different power ratings, output configurations, installation methods and environmental protection. Explore the main Leyu power supply categories below to find the right solution for your application.
Single Output Power Supply
Our single output power supplies provide one regulated DC output for industrial equipment, control systems, LED devices, electronic equipment and machinery.
Available product families cover compact open-frame and enclosed designs with different output voltages and power ratings, making them suitable for both equipment integration and general industrial applications.
DIN Rail Power Supply
Leyu DIN rail power supplies are designed for installation inside electrical cabinets, automation panels and control systems.
Compact DIN-mounted designs help simplify installation and save cabinet space while providing stable DC power for PLCs, sensors, relays, controllers, monitoring equipment and other automation components.
Available series include compact and higher-power configurations for different control cabinet requirements.
Multiple Output Power Supply
When different components require more than one DC voltage, a multiple output power supply can simplify system design and reduce the need for separate power modules.
Leyu offers dual, triple and multiple-output configurations for industrial control systems, electronic equipment, communication devices and other applications requiring several regulated DC outputs from one power supply.
UPS Charging Power Supply
Our UPS charging power supplies combine DC power delivery with battery charging functions for systems requiring backup power capability.
They can be used in security systems, access control, monitoring equipment, emergency systems, telecommunications equipment and other applications where temporary power interruption must be minimized.
Waterproof Power Supply
For outdoor equipment and applications exposed to dust or moisture, Leyu provides waterproof switching power supplies with fully enclosed or encapsulated designs.
Selected waterproof models are available with IP-rated protection and can be used for outdoor LED lighting, signage, surveillance equipment and other installations requiring additional environmental protection.
DC-DC Converter
Leyu DC-DC converters convert one DC voltage level into another regulated DC output, supporting equipment that operates from batteries, vehicles, DC distribution systems or other DC power sources.
They can be selected according to input voltage, required output voltage, power rating and equipment operating conditions.
High-Power Switching Power Supply
Our high-power switching power supplies are developed for industrial machinery, automation equipment and systems with higher power requirements.
Different output voltages and power levels are available to support applications where stable power delivery, thermal management and reliable continuous operation are important.
Find the Right Power Supply for Your Application
Selecting an industrial power supply should start with the electrical and installation requirements of your equipment rather than wattage alone.
Consider the following factors before choosing a model:
Confirm the available AC or DC input voltage at the installation site and verify that the selected power supply supports the required input range.
2. Output Voltage
Determine the regulated DC voltage required by the connected equipment, such as:
5V DC
12V DC
24V DC
36V DC
48V DC
Available voltage options vary by product series and model.
3. Required Output Power
Calculate the maximum power demand of the connected load and select a power supply with an appropriate engineering margin.
For motors, relays, LED loads and other equipment with startup or peak current, inrush current and temporary load conditions should also be considered.
4. Installation Method
Choose the form factor according to your equipment design:
DIN rail mounting for control cabinets
Enclosed power supplies for machinery and equipment
Open-frame designs for embedded installations
Waterproof designs for outdoor or humid environments
5. Operating Environment
Check the expected:
Ambient temperature
Humidity
Dust exposure
Water exposure
Ventilation
Vibration
Installation space
Environmental conditions can affect both the required enclosure and the usable power rating.
6. Protection Functions
Depending on the model, industrial switching power supplies may include functions such as:
Always verify the protection functions on the individual product datasheet before final selection.
7. Certifications and Target Market
Certification requirements depend on the destination market and end application.
When sourcing for a specific country or project, confirm the exact certification and compliance documentation available for the selected model before placing an order.
