MYRRA - AC/DC PCB Mount Power Supply - 3.3V 4.2W

The MYRRA 47000 series is a range of encapsulated electronic transformers based on Flyback topology, offering a modern and efficient alternative to traditional power supplies in applications requiring less than 5W. These switched-mode power supplies are designed to deliver high efficiency and very low standby power consumption, making them ideal for power management and industrial applications where energy saving is critical.

Compared to standard EI30 transformers, the 47000 series provides up to 3 times more power while maintaining the same footprint, allowing for easy upgrades without redesigning your PCB. They operate across a wide input frequency range of 47 to 440Hz and accept an input voltage from 85V AC to 265V AC, ensuring versatility in various global markets.

Safety and reliability are paramount. These power supplies are protected against output short-circuits and feature thermal shutdown with automatic recovery if the internal temperature exceeds allowable limits. This ensures long-lasting performance and peace of mind in demanding environments.

Key Benefits

• High efficiency and energy saving
• Very low standby power consumption (less than 200mW at no load)
• Increased power output (3x compared to standard EI30 transformer)
• Compact design with same footprint as EI30 transformer
• Robust protection features for enhanced reliability

Typical Applications

• Power management systems
• Industrial control equipment
• Information technology equipment (ITE)

The 47000 series is a reliable and efficient solution for your low-power PCB mount power supply needs. With its advanced features and robust construction, it ensures optimal performance and energy savings in a wide range of applications.
