Application Examples

1. Edge Computing Nodes in Production Lines

Modern production environments increasingly rely on decentralized edge systems – for example, to capture and pre-process sensor data directly at the machine. These edge nodes are often powered by existing 24 V supplies but require stable and isolated voltages for data processing and communication (e.g., 5 V or 12 V). ARCH ELECTRONICS DC/DC converters offer a compact solution with high EMC immunity and temperature tolerance, which is especially beneficial in machine enclosures with limited airflow.

2. Power Supply in Vehicle Communication Systems

In connected commercial vehicles (e.g., municipal vehicles or rail vehicles), control units for diagnostics, telematics, or driver assistance systems must be powered from the onboard voltage (12 V or 24 V) – often under strongly fluctuating voltage levels. Converters from the ARCH brand ensure stable output power even under transient voltage fluctuations, such as those occurring when starting engines or switching loads. The high isolation protects sensitive electronics from disturbances in the onboard network.

3. Powering Sensors and Gateways in Wind Turbines

In onshore and offshore wind turbines, sensors, controllers, and communication gateways often operate in exposed environments. ARCH modules are suitable for use in hubs, tower segments, or outdoor units, where temperature, humidity, and EMC requirements are high. Their compact design allows space-saving integration into existing control boxes or module carriers.

4. Communication Modules in Power Distribution Systems

In intelligent power distribution systems (smart grids), DC-DC converters provide power for data loggers, wireless gateways, or protection relays. The ARCH series supports safe operation through galvanic isolation and ensures reliable performance even at ambient temperatures up to +105 °C – for example, in densely packed distribution cabinets or outdoor units without active cooling.
