- Eurotech presents today the ACS-5125, a new MIL-rated PC/104 Plus power supply. The ACS-5125 is a 25W isolated module designed to meet the system requirements of military vehicle, aircraft, machine or vessel installations. The module supplies +5V @ 5A with overload protection and without any de-rating.
The ACS-5125 is compliant with EC low voltage directives and consists of a DC/DC converter and an optional EMC filter. The DC/DC converter meets the requirements for conducted emission and immunity of MIL-STD-461E (EMC performance) and of MIL-STD-810F (environmental performance). When the optional EMC filter is also mounted, the ACS-5125 additionally complies with MIL-STD-1275A/B/C & MIL-STD-704 (emission and immunity performance).
Additional features of the ACS-5125 DC/DC converter are 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 (at 102°C) that gives user control over the temperature shutdown function of the converter via an I2C interface. The optional EMC filter adds protection against conducted susceptibilities, surges and spikes.
Resistance to high levels of shock and vibration are a result of the mechanical solutions adopted in this ruggedised PC/104-Plus footprint compliant 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.
