Maximum continuous DC power supply voltage is 36VDC.
The InteliLite’s power supply terminals are
protected against large pulse power disturbances. When there is a potential risk of the controller
being subjected to conditions outside its capabilities, an outside protection device should be used.
It is necessary to ensure that potential difference between generator current COM terminal and
battery “-” terminal is maximally ± 2V. Therefore is strongly recommended to interconnect
these two terminals together.
Hint:
The InteliLite controller should be grounded properly in order to protect against lighting strikes!!
The maximum allowable current through the controller’s negative terminal is 4A (this is dependent on
binary output load).
For the connections with 12VDC power supply, the InteliLite
NT
includes internal capacitors that allow
the controller to continue operation during cranking if the battery voltage dip occurs. If the voltage
before dip is 10V, after 100ms the voltage recovers to 7 V, the controller continues operating. During
this voltage dip the controller screen backlight can turn off and on but the controller keeps operating.
It is possible to further support the controller by connecting the external capacitor and separating
diode or I-LBA module:
The capacitor size depends on required time. It shall be approximately thousands of microFarads.
The capacitor size should be 5 000 microFarad to withstand 150ms voltage dip under following
conditions:
Voltage before dip is 12V, after 150ms the voltage recovers to min. allowed voltage, i.e. 8V
Hint:
Before the battery is discharged the message "Low BackupBatt" appears.
