MYRRA 4W 5V 12V DC Regulated Power Supply

The MYRRA 4W 5V 12V DC Regulated Power Supply is a compact, encapsulated electronic transformer designed for PCB mounting. Based on efficient flyback topology, it offers a modern and reliable alternative to traditional power supplies for low-power applications under 5W. This unit provides two regulated DC outputs with a combined maximum power of 4 watts, making it ideal for powering sensitive electronic circuits where stable voltage is critical.

Featuring a wide input voltage range, it can accept mains power from 85V to 265V AC, ensuring compatibility with various international power grids. Its design prioritises energy efficiency with very low standby power consumption (under 200mW at no load) and an efficiency rating of 68%. An integrated fusible resistor provides robust input protection against electrical faults.

The power supply is built to operate reliably in a broad temperature range from -25°C to +60°C, making it suitable for use in challenging environments. Its compact, encapsulated housing ensures safety and durability while simplifying installation directly onto printed circuit boards. This makes it a perfect solution for embedded systems, control units, and small electronic devices requiring dual-voltage rails.

Key Features:

• Dual regulated DC outputs (5V and 12V).
• Wide AC input voltage range (85V - 265V AC).
• Very low standby power consumption.
• High efficiency and integrated input protection.
• Encapsulated, PCB-mount design for secure installation.
