They are designed for a wide range of applications, including power equipment, electronic instrumentation, communication systems, industrial automation control, and IoT.
The SKM/DKM series features an ultra-wide 8:1 input range (9-75VDC). Unlike previous generations that required multiple models with 2:1 or 4:1 input ranges (such as 9-18VDC, 18-36VDC, 36-72VDC, or 9-36VDC, 18-75VDC), this new series can cover 12VDC, 24VDC, and 48VDC with a single unit. This simplifies model selection, reduces inventory variety, and optimizes system design complexity.
Furthermore, to facilitate the upgrade of existing systems, the new and previous generations maintain pin-to-pin compatibility. This allows users to migrate to the new series without modifying the PCB design.
The main specification differences between the two generations are summarized in the table below:
CHARACTERISTICS
• 1”x1” form factor
• Ultra-wide 8:1 input range (9-75VDC)
• Natural convection cooling

• Compliant with EMI EN55032 Class A standard without external components (selected models)
• No minimum load required for stable operation
• Protections include short circuit, overload, overvoltage, and undervoltage
• Certifications: EAC/CE/UKCA
• 3-year warranty
