8 Technical description
General description
The charger charges the house battery by the alternator with the following charging current while driving:
• PSB12-40: 40 A
• PSB12-80: 80 A
• PSB24-40: 40 A
• PSB24-60: 60 A
• PSB12/24-20: 20 A
• PSB12/24-40: 40 A
• PSB24/12-40: 40 A
• PSB24/12-80: 80 A
The charger can be adapted to different battery types via DIP switches.
The charger offers the following functions:
• Microprocessor-controlled, temperature-compensated charging programs for various battery types
• Compliance with the charging characteristics even when the battery is charged with connected devices
• Ensures parallel operation of the charger with other charging sources, for example mains supply chargers, solar
systems, or generators
• Automatic compensation of voltage loss caused by the charging cable length (house battery)
• AUX connection usable for controller output, split-charge relay, or electrical devices (only PSB12-40, PSB12-80,
PSB24-40, PSB24-60)
• Compliance with N-BUS/Ci-BUS protocols
The charger has the following protective mechanisms:
• High voltage protection
• Low voltage protection
• High temperature protection
• Low temperature protection (only LiFePO4 batteries)
• Battery overcharge protection (only with optional temperature sensors)
• Reverse current protection
• Protection against short circuit
• Reverse polarity protection (only for house battery connection)
The charger can be connected to the DTB01/TD283 display (optional) for remote control. If a Bluetooth N-BUS de-
vice is present in the N-BUS network, the mobile app can be used for controlling the charger.
A temperature sensor TS002 (optional) can be connected to monitor the battery temperature during the charging
process.
