Siemens C39280-Z4-C510 power supply unit for OptiPoint 410/420 IP phones.
The Siemens C39280-Z4-C510 is a dedicated power supply unit designed to provide mains power to Siemens OptiPoint 410 and OptiPoint 420 series IP telephones. This PSU enables deployment of these handsets in locations where Power over Ethernet is unavailable or impractical.
The OptiPoint 410 and 420 series were executive-grade SIP and HFA IP phones within the Siemens Enterprise Communications portfolio, commonly deployed alongside HiPath communication platforms. This power supply ensures reliable operation of these feature-rich handsets in enterprise telephony environments.
The OptiPoint series has been discontinued following the transition of Siemens Enterprise Communications to Unify. However, many organisations continue to operate legacy HiPath and OpenScape systems where these handsets remain in active service, maintaining demand for compatible accessories and power supplies.
