MYRRA 9V 5W Encapsulated PCB Mount Power Supply

The MYRRA 9V 5W Encapsulated PCB Mount Power Supply (47000 series) is a high-efficiency switched mode power supply based on Flyback topology. It offers a modern, energy-saving alternative to traditional linear supplies for applications requiring up to 5W of power. With its compact, encapsulated design and PCB mount format, this unit is engineered for reliable, continuous performance in a wide range of industrial and power management applications.

This power supply delivers a fixed 9VDC output at 560mA, with a wide input voltage range of 85VAC to 265VAC and an input frequency of 47 to 440Hz. It boasts increased power output—up to 3 times that of a standard EI30 transformer—while maintaining the same footprint, making it an ideal drop-in upgrade for existing designs. The unit features very low standby power consumption (less than 200mW no load) and better energetic efficiency, contributing to reduced energy costs and lower environmental impact.

Built-in protection includes output short-circuit protection and thermal shutdown with automatic recovery when internal temperature exceeds allowable limits. The encapsulated construction protects against dust, moisture, and mechanical damage, ensuring long-term durability in demanding environments.
