Sennheiser 509454 – EW-D Power Supply with Adapters

Product Overview

This is the genuine Sennheiser EW-D power supply for Evolution Wireless Digital receivers and chargers, supplied with international country adapters. It provides regulated 12V DC power for an EW-D EM receiver or compatible EW-D charging accessory, making it a direct replacement or spare for installed and touring wireless systems. The included country adapter set lets the same supply travel between regions without rewiring.

Product Description

The Sennheiser 509454 EW-D power supply delivers a regulated 12V DC, 1A output for the Evolution Wireless Digital platform from a 100-240V wall input. It ships with a set of interchangeable country plug adapters, so a single supply can power EW-D equipment across US, EU, UK, and other regional outlets. This is the same power supply Sennheiser specifies for the EW-D EM receiver and EW-D charging accessories, which makes it the correct choice for a spare or replacement rather than a generic third-party adapter. AV integrators and rental houses commonly keep spare power supplies in inventory because a failed or misplaced supply takes an entire wireless channel out of service. The universal input and adapter set also simplify touring logistics for productions that move between countries. Using the manufacturer supply ensures the correct voltage, polarity, and connector for EW-D hardware.
