100W 24V DC LRS Industrial Switching Power Supply

The LRS-100-24 switching power supply delivers 24V DC at 4.5A, rated 100W. It is sized for single-device and small-cluster loads - a CCTV camera bank, LED strip segments, a 3D printer, or a small control panel. The case measures 129 × 97 × 30 mm, giving this 100W power supply a compact footprint that fits into narrow enclosures and 1U-height equipment cabinets. This AC-DC enclosed power supply belongs to the LRS series power supply family from CHNANMA, and more output voltage choices can be provided upon request.

Heat Dissipation and Installation
This AC-DC enclosed power supply relies on passive cooling. The ventilated metal mesh casing forms the heat path, and no fan is fitted inside the 100W power supply. Operation stays quiet, and there is no fan to service. At 30mm tall, this space-saving industrial power unit fits inside standard 1U-height enclosures and slim control boxes. Keep casing openings unobstructed for smooth airflow during continuous operation.The unit is rated for a 50°C ambient temperature. In a sealed or crowded cabinet, leave extra space so the heat has somewhere to go.
Application Scope
The LRS-100-24 switching power supply works well for a wide range of industrial and commercial systems. This AC-DC enclosed power supply can serve as the power source for monitoring equipment, LED lighting assemblies, small automation control panels and 3D printing equipment. As one model of the LRS series power supply, it fits projects that require stable 24V DC power within the rated load range.
Material and Factory Standard
CHNANMA builds the 24V 100W industrial power supply with a pure copper transformer and copper windings. Each 100W 24V DC switching power supply ships directly from our factory, with standard quality-control procedures applied through the production cycle.
FAQ
Q: Does this 100W power supply need an external cooling device?
