Model: 777-PM3WCX-US

Integrated Wall System for 3.5-V Diagnostic Instruments

The Green Series™ 777 Wall Transformer (777-PM3WCX-US) is a premium, energy-efficient, wall-mounted power system designed for clinics and exam rooms that rely on Welch Allyn 3.5-V diagnostic tools. It delivers consistent, dependable illumination while improving infection-control practices and eliminating the need for frequent bulb or battery replacements.

Instruments power on when lifted from the cradle and turn off when returned, reducing energy consumption and extending lamp life.

No external switch helps minimize contact points, contributing to a cleaner, safer clinical environment.

Fully compatible with Welch Allyn 3.5-V instrument heads—including LED and traditional illumination technologies.
