The module supplies +5V @ 5A with overload protection and without any de-rating. The ACS-5125 features a DC/DC converter that provides well-controlled outputs with no overshoot and control functions such as voltage trim, remote sense and inhibit. It can also generate an over temperature warning signal that gives the user control over the temperature shutdown function of the converter via an I2C interface. In conjunction with the DC/DC converter, the ACS-5125 can also be equipped with EMC filtering against conducted susceptibilities, surges and spikes. Resistance to high levels of shock and vibration are a result of the mechanical solutions adopted in this ruggedized PC/104-Plus compliant (except for component heights) module: these include the use of the PCB for heat dissipation, component selection and extensive use of SMD components. In addition, the power supply construction allows for the EMI filter, DC/DC converter and the heat dissipating protection devices to be mounted on the top or on the bottom side of the board. This allows for the maximum configuration flexibility when integrating the ACS-5125 in a system and easily supports the use of structural heat sinking enabling reliable temperature operation (-40 to +85 °C) without any active cooling. The ACS-5125 meets requirements of EC low voltage directives for CE compliance. When the power supply module only features the DC/DC converter, it meets the conducted emission and immunity requirements of MILSTD-461E (EMC performance) and MIL-STD-810F (environmental performance). When the EMC filter is also mounted, the ACS-5125 additionally complies with MIL-STD-1275A/B/C & MIL-ST
