PAXTON Power Supply 857-090 2A / 12V DC No Housing

The Paxton 857-090 is a 2A, 12V DC power supply module designed specifically for the Net2 networked access control system. Supplied without an outer casing, this unhoused module is ideal for custom installations, integration into existing enclosures, or as a direct replacement unit.

Engineered for reliable performance, the module connects to a standard UK mains supply via a switched fused spur. It features an integrated tamper switch that triggers an alarm if the enclosure is opened while connected to an Access Control Unit (ACU) or I/O board, helping to maintain system integrity.

Please note that this power supply is not weatherproof. If it is to be installed outdoors, it must be housed inside a suitable waterproof casing.
