General characteristics
- Low power variation : max 25 % of nominal power
- Operating temperature : -25° to +70°C (Peak of +85°C – T3 Class in conformity with EN 50155)
- High number of ignitions (>100.000) – optimal preheating for an increased lamp lifetime
- High resistance to vibrations and shocks (in conformity with EN 61373)
- EMC Electromagnetic compatibility (in conformity with EN 50121-3-2)
- Fire and smoke approval (in conformity with EN 45545)
- Conformity to standard railway norms
Protection against
- Input polarity reversal
- Open-circuit and low voltage conditions
- Short-circuit on the ouput terminals
- Internal short-circuit (fuse protection)
- Lamp failure
