DC/DC converters and battery-network stabilisers
DC/DC converters supply sensitive electronics from a network whose voltage moves with the battery charge. Battery-network stabilisers hold the voltage within tolerance through large swings and overloads.
- Rolling stock and urban transit
- Substations
- Telecommunications
- Control systems
- Wide input voltage range
- Galvanic isolation between input and output
- Parallel operation
- Short-term overload capability
- Over-temperature protection
- Continuous no-load operation and short-circuit proof
