e Purkeys Direct™ nosebox system combines all the best features of
our original ligate charging systems with a space-saving nosebox that
helps standardize the front of the trailer. It also includes an interior light
controller (harness sold separately) designed to turn the lights on inside a
trailer and automatically shut them o either:
• via a timer
• if the truck starts
• if the ligate batteries drop to a low state of charge.
e Direct improves the charging of ligate batteries by utilizing a DC/
DC Converter to boost the voltage for optimal charging. e boost in
voltage overcomes the normal voltage drop caused by the extended
distance between the ligate batteries and the vehicle charging system.
Also, in cold temperatures batteries require increased charging voltages to
maintain a high state of charge. e DC/DC Converter in the Direct system
compensates for temperature as well as for voltage drop and provides the
best voltage to the remotely located ligate batteries. e result is well-
charged ligate batteries that will last longer and have ample power for
ligate operation.
e Direct nosebox system is automatic and has easy to interpret LED
indicators to assure drivers and technicians of proper system function. e
LED indicators clearly show the status of the source as well as the status
of the ligate batteries. A quick glance at the Direct Controller assures the
driver that the ligate batteries are ready to go, or alerts the driver that the
batteries need maintenance.
NOTE: Our ligate charging systems are designed to work with ooded cell
and AGM batteries. If you are using this system to charge any other type of
battery, please contact us at 479-419-4800 before installation.
