MEAN WELL EPS-25-7.5 25W jednovýstupný open-frame napájací zdroj, 7,5V DC 3,33A, vstup 80-264VAC, montáž na PCB

The EPS-25-7.5 from MEAN WELL stands out as a compact open frame power supply that delivers a stable 7.5 V DC output with a full 25 W of power, yet consumes less than 0.1 W at no load. Unlike many budget units, it accepts a universal AC input from 80 to 264 VAC without any switching, making it suitable for global use. Its low-profile PCB design and free air convection cooling allow it to fit into tight industrial enclosures where forced airflow is not available.

Highlights

• Universal input range: 80 ~ 264 VAC / 113 ~ 370 VDC
• High efficiency up to 87% and low no-load power consumption < 0.1 W
• Protections: short circuit, overload, over voltage
• 3 kVAC isolation between input and output
• Safety approvals: UL62368-1, TUV EN62368-1, CB IEC62368-1, CE
• Operating temperature from -30 °C to +70 °C

In daily use

This power supply is ideal for industrial automation, instrumentation, and communication equipment that require a reliable low-voltage DC rail. The open frame construction allows direct PCB mounting, saving space and simplifying integration. With a hold-up time of 16 ms at full load and 230 VAC, it rides through brief input interruptions, preventing unexpected resets. The output ripple and noise are kept below 100 mVp-p, ensuring clean power for sensitive circuits.
