Overview
The Unify OpenStage Mains Adaptor (UK), identified by part number L30250-F600-C142, is a 15-watt external power supply unit designed for the entire range of Unify and Siemens OpenStage and OptiPoint telephones. It is specifically required for installations where Power over Ethernet (PoE) is unavailable or when power-intensive accessories, such as OpenStage Key Modules, are added to the device. The adapter features a standard UK 3-pin plug and delivers a stable output of 38V DC at 420mA, ensuring consistent performance for professional desktop environments. Its broad compatibility includes all TDM, HFA, and SIP variants of the OpenStage series, as well as older OptiPoint 410 and 420 models. This reliable AC-to-DC converter is essential for maintaining the full functionality of executive-level communication systems when used with standalone power sources.
