linear power supply-MKAC-41-240450M

1. Stable 22V Linear Output for Noise-Sensitive Applications

Unlike high-frequency switch-mode adapters, this MKAC-41-240450M uses a linear power supply structure with an EI transformer to provide low ripple and low noise 22.0 V DC output. It is especially suitable for applications such as audio amplifiers, analog measurement circuits, security control boards and other equipment that are sensitive to power noise and ripple.

2. Optimized for 120V / 60Hz Markets

The adapter is designed for 120 V, 60 Hz input with a fixed AC plug, making it ideal for use in North America and other regions using 120 V mains. The compact housing design helps you save space in retail packaging and finished equipment.

3. Complete Protection – OCP/OVP/SCP

Built-in over-current protection (OCP), over-voltage protection (OVP) and short-circuit protection (SCP) safeguard both the adapter and the end equipment. In case of abnormal load or wiring, the power supply will limit or shut down the output to prevent damage and reduce after-sales risk for your project.

4. Certified to Global Safety and EMC Standards

MKAC-41-240450M meets international safety and EMC standards including UL62368, EN62368, FCC PART 15, EN55032 and GB4943.1. With these certifications, you can integrate this adapter into your products and accelerate market access in major regions without re-doing the full power supply certification.

5. EU Level VI Energy Efficiency

The design complies with EU Level VI energy efficiency requirements, reducing standby power consumption and improving overall system efficiency. This helps your brand meet the latest environmental regulations and energy-saving requirements from end users and distributors.

6. Compact Size and Robust Housing

With dimensions of 52 × 64 × 41 mm and a weight of 346.23 g, the adapter provides a good balance between thermal performance and portability. The robust plastic enclosure is suitable for daily use in home, office, security and light industrial environments.

7. OEM / ODM Customization Available

Besides the standard 22.0 V / 450 mA output, Macable can customize plug type, DC connector, cable length, label, housing color and packaging according to your project requirements. Our engineering team can also help evaluate your load and suggest optimized output voltage/current specifications to ensure long-term stable operation.
