Single Board Computer ACS-5161
The ACS-5161 is a galvanically-isolated dual-output DC/DC power converter in a PC/104 form factor. Providing up to 100 watts of peak power (minimum 60 watts continuous at extended temps if not structurally heatsinked), the ACS-5161 features a special mechanical design hardened for extreme temperatures and high levels of shock and vibration, making it ideal for aircraft, rail, ship or industrial installations. All the components are securely fixed to the board for shock/vibration resistance.
Intended to be bottom board of a PC/104 card stack, the power supply incorporates a DC/DC converter module placed on its bottom side, so that it can be structurally heatsinked to a thermally conductive base or enclosure wall - to enable reliable extended temperature operation (-40°C to +85°C) without any active cooling. The output voltages are driven into the PC/104 bus and can also be accessed from easily removable terminal blocks on the side of the module. Indicator LEDs show the status of the power outputs. The power supply can be switched ON/OFF remotely with a switch or ignition key of a vehicle.
Input protected and filtered, the ACS-5161 is ideal for battery-operated +24V DC nominal systems. It offers reverse protection up to -45V DC and short-term tolerance of spikes up to 50V (1ms). It also supports configurable timing for power sequencing, as well as remote shutdown. The onboard common mode input filter and protection circuitry is designed to meet the requirements of the EC low voltage directives for CE compliance EN55022-B and EN61000 and MIL-STD-461 for conducted and radiated emissions. Integration of the filter stage on-board makes system integration easier, eliminating external pre-filter boards. Emissions are reduced by optimal board layout, as well as EMI filtering of all the outputs of the board including the power that is supplied into the PC/104 bus.
