1.5 TECHNICAL INFORMATION
Power Requirements
The DC power for the Chief is supplied through direct connection to the base circuit board. The DC
power is internally protected with a 20 amp auto-resetting circuit breaker. The Chief will operate from
either 12 or 24 volt DC power with no customer changes necessary. The electronic system has built in
reverse polarity protection. For optimum performance, a minimum of 11 volts is required at the Chief
base. Long runs of cable can introduce power loss For long runs, it may be necessary to add an
intermediate junction box in the DC cable so that DC power can be applied closer to the Chief.
