MYRRA 2.75W 5V DC Regulated Power Supply
Efficient MYRRA 5V 2.75W power supply with wide input range, ideal for industrial and standby applications.
The MYRRA 2.75W 5V DC Regulated Power Supply (Part No. 47122) is a high-efficiency, encapsulated electronic transformer based on flyback topology. This switched-mode power supply offers a superior alternative to traditional linear transformers, delivering nearly three times more power than standard EI30 transformers with better energy efficiency (68% typical vs. 40% for conventional supplies). Designed for versatility, it provides reliable 5V DC power for a variety of applications while consuming minimal standby power.
Key Features:
- High Efficiency: 68% typical efficiency reduces energy waste significantly.
- Wide Input Range: Operates from 85–265V AC or 85–370V DC with a frequency range of 47–440Hz.
- Compact Footprint: Matches the dimensions of EI30 transformers, making it a seamless replacement.
- Robust Protection: Includes integrated fusible resistor, short-circuit protection, and thermal shutdown with auto-recovery.
Applications: Ideal for industrial power management, standby devices, and auxiliary power in AC/DC or DC/DC applications. Suitable replacements for both linear transformers and DC-DC converters.
Note: Market demand may cause lead-time fluctuations, and discounts do not apply.
