The selection of the appropriate voltage depends on the voltage requirements of the connected devices; common voltage levels in industrial applications include 5V, 12V, 24V, and 48V, with 24V power supplies being the most widely used.
In addition to voltage, you must also consider factors such as current capacity, voltage tolerance, and future requirements for system expansion. If you are uncertain during the selection process, please contact LCTC; we are here to support you with technical assistance.
When selecting a suitable switching power supply for rail mounting, the output voltage, output current, power requirements, installation specifications, and operating environment should be taken into account first.
It is recommended to plan a 20% to 30% reserve in the device’s power capacity; the installation environment should ideally promote good heat dissipation, and when mounting in an electrical cabinet, adequate ventilation must be ensured.
If you are unsure about the specific choice, please contact LCTC; we offer professional assistance in selecting the right option.
Installing the DIN rail switching power supply is simple and convenient; no additional fixtures or complicated installation procedures are required. However, before installation, please ensure that the power supply’s technical specifications—such as input voltage, output current, and load capacity, meet the requirements of your application.
First, mount the switching power supply onto a standard 35 mm hat rail and secure it using the integrated clip.
Connect the AC power supply to the input terminals; ensure that the connections for phase, neutral conductor, and protective conductor are properly made to guarantee safety.
Connect the plus and minus terminals to the respective devices, such as PLCs, sensors, etc.
After completing the wiring, verify that all connections are correct before turning on the system, and then ensure that all connected devices are functioning properly.
Ensure that there is sufficient space at the installation location for ventilation and heat dissipation.
Typical devices powered by a DIN rail switching power supply include: PLCs, HMI panels, industrial sensors and transmitters, relay modules and contactors, communication equipment, industrial control components, etc.
Regardless of the connected device, it must be ensured that the output voltage and current capacity meet the overall power requirements of the connected equipment.
Yes, as long as the total power consumption of the connected devices remains within the rated capacity of the DIN rail switchgear, multiple devices can be supplied with power simultaneously.
Yes, if you require additional power capacity or independent power supplies, you can combine multiple switching power supplies for the track mounting; this is a common method to provide flexible and scalable power supply solutions for complex industrial automation systems.
When installing multiple switchgear units for rail mounting, consider factors such as power distribution requirements, space allocation and ventilation in the switchgear cabinet, load capacity, and system configuration.
It using high-frequency switching technology to convert and regulate voltage, it transforms the input electrical energy into a DC output.
DIN rail power supply refers to two independent voltage output lines, not two mounting rails, so it differs from a DIN rail switching power supply.
In most cases, DIN power supplies are mounted vertically on standard 35 mm rails to facilitate airflow and heat dissipation; however, horizontal mounting is also possible, provided there is sufficient space for ventilation and cooling.
The required space depends on the rated power, installation environment, and operating conditions. It is generally recommended to leave a 20-50 mm gap above and below the power supply to ensure effective air circulation.
Avoid installing the heat-generating components directly next to the DIN rail switching power supply during installation, and ensure that ventilation openings are not blocked.
LCTC DIN rail switching power supplies are available with CE certification and RoHS compliance.
Certification availability may vary depending on the specific model, you can contact LCTC for detailed certification documents and product compliance information.
DIN Rail Switching Power Supply VS Enclosed Power Supply
DIN power supplies and enclosed types are both widely used in industrial automation and electrical control systems; although they perform similar functions, they differ significantly in terms of construction, mounting methods, and other aspects. I will use a table to clearly illustrate these differences.
