Description
Product Overview
The BACHMANN DPM200 is a high-efficiency, rail-certified power supply module engineered for mission-critical automation systems in transportation and industrial environments. As the primary power conversion unit in Bachmann’s M1 control platform, the DPM200 delivers stabilized 24V DC power to CPUs, I/O modules, and communication interfaces while operating flawlessly under extreme conditions. Designed to EN 50155 railway standards, it withstands voltage fluctuations (0.7–1.25 times nominal input), temperature extremes (-40°C to +70°C), and mechanical stress (5g vibration/50g shock). The module features active power factor correction (>0.95) and 92% peak efficiency, minimizing heat dissipation in enclosed cabinets. With built-in redundancy support via parallel operation and comprehensive diagnostics, the BACHMANN DPM200 ensures uninterrupted power for safety-critical applications like train control, tunnel ventilation, and industrial process automation. Its integrated health monitoring communicates real-time status via POWERLINK backplane, enabling predictive maintenance and reducing system downtime.

BACHMANN DPM200
Main Features and Advantages
Ultra-Wide Input Range: The DPM200 accepts 24–110V DC without external converters, supporting locomotive batteries (74V/110V) and industrial 24V/48V systems. Handles 100ms voltage drops to 16V DC and 500ms surges to 150V DC.
Redundancy Architecture: Parallel connection of multiple DPM200 modules enables N+1 redundancy. Automatic current balancing (±5%) and hot-swap capability ensure zero power interruption during maintenance.
Diagnostic Intelligence: Real-time monitoring of output voltage/current, temperature, and efficiency via POWERLINK. Predictive failure alerts for capacitor aging or fan degradation reduce unplanned downtime by 60%.
Rail-Hardened Design: Conformal-coated PCB withstands 95% humidity (non-condensing). Reinforced heat sinks maintain full load capacity at 70°C ambient – critical for engine rooms or steel plants.
Safety Compliance: Short-circuit current limitation (<13A) prevents cable damage. Reinforced isolation meets EN 50155 Clause 12.4.11 for rolling stock applications.

Application Field
The BACHMANN DPM200 powers safety-critical systems in extreme environments:
Railway Vehicle Control: Primary power for M1 control cabinets in locomotives/trams, surviving EN 50155-defined voltage transients and vibrations.
Tunnel Safety Systems: Ensures uninterrupted 24V supply to emergency lighting, fire alarms, and ventilation controls during power fluctuations.
Mobile Machinery: Powers hydraulic controllers and sensors in port cranes/mining trucks, resisting salt spray and shock loads.
Renewable Energy: Stabilizes DC power in wind turbine pitch systems despite generator voltage ripple.
Industrial Safety: SIL 2-compliant power for emergency stop circuits in chemical processing plants.

Installation and Maintenance
Pre-installation preparation: Verify input voltage compatibility and derate power above 40°C ambient. Ensure proper heat dissipation space (≥50mm above/below). Use copper conductors (min. 2.5mm²) with torque-controlled terminals (0.6Nm).
Maintenance recommendations: Monitor operating hours and efficiency trends via M1 diagnostics software. Clean ventilation slots biannually with dry air. Replace electrolytic capacitors after 50,000 hours in high-temperature environments. Test redundancy switchover annually.
