MODEL 6929
12V Source to 24V Battery; 45A
CONNECTIONS
OUTPUT
INPUT
Model 6929 may be factory programmed for Lithium batteries with other chemistries
Electronic vertical knee type at power limit with shutdown
requiring rest if voltage drops below 45V
YES - control terminal may be connected to 12V terminal
on control block via switch or relay or
may be connected to 12V via the ignition switch.
Model 6929 is designed to meet the emerging need to charge lithium battery banks
from 12V systems. Model 6929 will output 45A @ 29V in full charge mode and can
be operated while load is drawn from the battery bank being charged. Off the shelf
units are ideal for use with lithium iron phosphate batteries. Model 6929 is
microprocessor controlled and can be programmed at factory for operation with
other battery types.
