Dehner Elektronik SPB 100-05 AC/DC Built-in Power Supply 18 A 100 W 5 V/DC Stabilized

When industrial and automation systems demand a reliable 5 V DC power source with high current capability, the Dehner Elektronik SPB 100-05 delivers stable, regulated output in a compact built-in format. This 100 W AC/DC power supply converts 100–240 V AC mains input to a precisely stabilized 5 V DC at up to 18 A, making it ideal for embedded controllers, sensors, actuators, and other power-hungry components. Its enclosed metal housing and screw terminal connections ensure secure integration into control cabinets and machinery, while convection cooling keeps operation silent and maintenance-free.

Who is it for

Engineers, system integrators, and maintenance technicians working on industrial automation, embedded systems, or custom electronics will appreciate the SPB 100-05 for its robust design and dependable performance. It suits applications that require a fixed 5 V rail with ample current headroom, such as PLC auxiliary supplies, LED lighting arrays, motor drivers, and communication modules. Whether you are building a new panel or replacing an aging supply, this unit provides a straightforward drop-in solution.

Tips

Ensure adequate ventilation around the unit to maintain optimal operating temperature, especially when running near full load. Use appropriately sized wires for the 18 A output current to minimize voltage drop. For DIN rail mounting, consider a compatible adapter bracket if required. Always verify that the total load does not exceed 100 W to avoid triggering the overload protection.
