Overview

The Schlage PS902 is a 2-amp power supply that offers a high degree of configurability to address the changing needs of the electronic access control market. Designed with versatility and reliability in mind, the PS902 can be factory ordered to meet specific needs or configured in-field using a wide selection of option boards. Their use of separate battery management ensures tight output power regulation to protect downstream devices.

Installation is simple with a flat mounting board and polarized locking connectors to make in-field expansions virtually plug-and-play. The design also provides easier access to the terminal blocks for connection of electrified devices, such as electric strikes, mag locks and card readers.
