Schlage PS902 2 amp Power Supply

The Schlage / Von Duprin PS902 is a versatile 2-amp power supply designed to deliver consistent and reliable low-voltage power for various electronic access control devices, including electrified locks, electromagnetic locks, and card readers. It offers a field-selectable output of either 12V or 24V DC, allowing flexibility to meet specific system requirements. The unit operates on a universal input voltage range of 120 to 240V AC at 50/60 Hz, making it suitable for diverse installation environments. Its regulated and filtered DC output ensures the protection and optimal performance of connected devices.

Designed with user convenience in mind, the PS902 features LED indicators that provide clear status updates for both AC input and DC output voltages. The enclosure, measuring 14 inches in height, 12 inches in width, and 4 inches in depth, is constructed with a gray baked-enamel finish and includes a hinged cover with lock-down screws for enhanced security and ease of access. Additionally, the power supply is compatible with various optional distribution boards, such as the 900-2RS, 900-2Q, and 900-4R, allowing for expanded functionality to suit specific application needs.
