LDC160

LDC160 is a six channel non-isolated bidirectional battery charger/power management system for power management and charging in a multi-power vessel such as airship, marines, heavy duty vehicles, and stationary multi-port systems. The six-channel unit is rated for 160kW combined power, and the three-channel unit is rated for 80kW.  Each channel is a non-isolated bidirectional port that can handle an input voltage of zero to Vbus.  During the startup periods, the unit can pre-charge the main bus using any of the channels.  Droop control allows wireless power sharing between up to 16 units.  Each unit will prioritize charge and discharge of each channel based on the voltage of the respective channel.  Fully automated to operate even during the total loss of communication.

Suitable for

• Airship, marine, submarine, and heavy-duty vehicle applications
• Multi-port stationary power management systems
• Power sharing among multiple battery banks
• Wireless power sharing in large systems

Key features

• Supports battery management per channel
• 2 isolated CAN channels
• Supports dc bus formation using one of the channels for bootstrapping the system
• Wireless power sharing and operation of multiple units through droop control
• Automated charging priority assignment to lowest voltage port
• Automated discharging priority assignment to highest voltage port
• Ports will automatically share power with ratio based on their respective voltage
• High side bus pre-charging and main breakers rated for 900Vdc
• Pre-charge capability for the main bus
• Channels can go down to 0V
• Liquid cooled at 5L/min+ with 2 PSI pressure drop
• IP67 rated
• Support for 3 auxiliary relays
