35
Maximum allowable DC power supply voltage is 39VDC.
The InteliDrive Lite’s power supply terminals are protected against large pulse power disturbances.
When there is a potential risk the controller being subjected to conditions outside its capabilities, an
outside protection devise should be used.

INT
The InteliDrive Lite 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 InteliDrive Lite includes internal capacitors that
allow the controller to continue operation during cranking if the battery voltage dip occurs. If the
voltage before dip is 12V, after 150ms the voltage recovers to 7V, 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 or I-LBA module.
The capacitor size depends on required time. It
shall be approximately thousands of uF
(microFarads). The capacitor size should be
5000uF to with stand 150ms voltage dip under
following conditions:
Voltage before dip is 12V, after 150ms the
voltage recovers to minimum allowed voltage
i.e. 8V
The I-LBA module ensures minimaly 350ms
voltage dip under following conditions:
RS232 and other plug-in module is connected.
Voltage before dip is 12V and after 350ms the
voltage recovers to minimum allowed voltage
5V. The I-LBA enables controller operation
from 5V (for 10 to 30 sec). The wiring
resistance from battery should be up to 0.1
Ohm for I-LBA proper function.
4.1.4 Power supply fusing
A one-amp fuse should be connected in-line with the battery positive terminal to the controller and
modules. These items should never be connected directly to the starting battery.
Fuse value and type depends on number of connected devices and wire length. Recommended fuse
(not fast) type - T1A. Not fast due to internal capacitors charging during power up.
