The Protege DIN Rail 4A 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 4 Amps total. Additionally, a battery charging circuit current of 500mA is also provided by the module. 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.The Protege DIN Rail 4A 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 interconnects to other modules. Utilizing the latest flash technology and high performance communication mediums the firmware of the Protege DIN Rail 4A Intelligent Power Supply can be updated using the ICT Loadit utility over the Protege system module network.
