MEAN WELL GSM40A07-P1J Medical-Grade 40W AC/DC Power Supply with 7.5V DC Output and 2.1x5.5mm Barrel Plug

The GSM40A07-P1J stands out as a medical-grade desktop power supply that delivers a stable 7.5V DC output with 2xMOPP isolation, making it suitable for patient-contact applications where safety and reliability are non-negotiable. Unlike generic adapters, this unit combines a wide 80–264VAC input range with Class II construction and ultra-low leakage current, ensuring compliance with stringent medical standards without compromising on efficiency or compactness.

Highlights

• 40W continuous output at 7.5V DC / 5.34A for demanding medical devices
• 2xMOPP safety approval (ANSI/AAMI ES60601-1, IEC/EN60601-1) for patient vicinity use
• Wide input voltage range 80–264VAC with IEC 320-C14 inlet for global operation
• High efficiency up to 88.5% and no-load consumption below 0.1W (Level VI compliant)
• Comprehensive protections: short circuit, overload, over voltage, over temperature
• DC output via 2.1 x 5.5mm barrel plug, center positive

In daily use

In clinical or home healthcare settings, the GSM40A07-P1J provides clean, low-ripple power (100mVp-p) that protects sensitive electronics. Its free-air convection cooling means silent operation, while the wide operating temperature range (-30°C to +70°C) ensures dependable performance even in challenging environments. The compact, lightweight design simplifies installation and cable management, and the standard C14 connector allows use with commonly available AC cords.
