SM1228 Voltage Converter Module (24VDC to 12VDC)

The SM1228 Voltage Converter Module is a compact voltage reduction module designed to convert a 24VDC input to a regulated 12VDC output. Suitable for commercial, industrial, educational, healthcare, residential, and public sector environments, it provides a simple and reliable solution for powering 12VDC devices from a 24VDC power source.

Designed with a compact footprint, the SM1228 is ideal for installations where mixed-voltage equipment is used. By reducing a 24VDC supply to 12VDC, the module allows compatible access control devices, intercoms, readers, relays, and other electronic security equipment to operate from a common 24VDC power supply.

Its small size makes it easy to install inside control panels, junction boxes, and equipment enclosures where installation space is limited.
