FAQ |
|---|
| Q1: What makes a power supply suitable for railway applications? |
| A: Railway-specific supplies are built for high electrical noise immunity, wide voltage input ranges, mechanical ruggedness, and extended temperature operation to survive the harsh and electrically noisy environment near tracks and trains. |
| Q2: Can this supply be used for both trackside and onboard (rolling stock) applications? |
| A: Our series includes models suitable for trackside/fixed installations. For onboard use (e.g., in a train carriage), compliance with standards like EN 50155 is critical, and we offer models developed to meet such requirements. |
| Q3: How does it handle power surges from the railway traction system? |
| A: It incorporates heavy-duty surge protection devices (SPDs) and advanced filtering at the input stage to clamp high-voltage transients and prevent them from reaching the sensitive connected equipment. |
| Q4: Can you provide power supplies for special railway frequencies like 16.7Hz? |
| A: Yes. We can engineer custom solutions for special railway electrification frequencies, including 16.7Hz used in some European countries. |
| Q5: What information is needed for a quotation? |
| A: Please provide: Application (e.g., signaling, station), Required Input Voltage/Frequency, Required Output Voltage/Power (kVA), Environmental Conditions, and any specific industry standards that must be met. |
