DIN Rail 8A Intelligent Power Supply


The Protege DIN Rail 8A Intelligent Power Supply provides 12VDC power ideal for running security, access control or automation devices along with large numbers of Protege network powered modules in the same installation. The Protege DIN Rail 8A Intelligent Power Supply is designed for use with industry standard DIN Rail mounting.

Key Features:

Reliable Power

The Protege DIN Rail 8A Intelligent Power Supply is capable of supplying power to a large number of smaller devices or multiple high current devices with a combined output of 7.5 Amps total and a battery charging circuit current of 500mA. A continuous source of power is maintained with the inclusion of intelligent battery backup charging, optimal level maintenance and seamless switch on AC failure. The battery backup, AC status and core temperature, are constantly monitored and failure conditions are communicated to the Protege System.

Intelligent Power Monitoring

The Power Supply is able to relay information about critical system voltages, currents and core temperature to the Protege Integrated System Controller by registering as an analog expander module on the Protege network. The Protege Integrated System Controller can then store these values in system registers that can be viewed live from the Protege System Management Suite software. This allows live viewing of the system voltages, currents and core temperature along with logging for review at any time.


Single RS-485 communication interface port used for all network communication functions and interconnection to other modules.

Upgradable Firmware

Utilizing the latest flash technology and high performance communication mediums, the firmware can be updated using the ICT Loadit utility over the Protege system module network.
