Automotive Relays
High Current Devices
Battery Disconnect Switch BDS-A (Latching)
■ Limiting continuous current 190A at 85°C
■ Electrically settable and resettable ON/OFF bistable device
■ High peak current carrying capability up to 1500A1)
Typical applications
Preheating systems (e.g. for diesel engines, catalytic converters), battery
disconnection to prevent fire caused by short circuits during an accident,
dual battery applications provide the start reliability by a separate starter
battery, keeps the power net in balance and to control and secure the
health of the energy storage systems, seasonal, service and transport
deactivation, high current switching, energy management, battery coupling.
