4.7.3 Power supply
Use minimally power supply cable of 1.5 mm
2
.
IMPORTANT: Maximum continuous DC power supply voltage is 36 VDC.
Maximum allowable DC power supply voltage is 39 VDC.
The ID-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.
Note: The ID-Lite controller should be grounded properly in order to protect against lighting strikes!! The
maximum allowable current through the controller’s negative terminal is 4 A (this is dependent on binary output
load).
For the connections with 12 VDC power supply, the ID-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 12 V, after
150 ms 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 or I-LBA module.
The capacitor size depends on required time. It shall
be approximately thousands of uF (microFarads).
The capacitor size should be 5000 uF to with stand
150 ms voltage dip under following conditions:
Voltage before dip is 12 V, after 150 ms the voltage
recovers to minimum allowed voltage i.e. 8 V
The I-LBA module ensures minimally 350 ms voltage
dip under following conditions:
RS232 and other plug-in module is connected.
Voltage before dip is 12 V and after 350 ms the
voltage recovers to minimum allowed voltage 5 V.
The I-LBA enables controller operation from 5 V (for
10 to 30 sec). The wiring resistance from battery
should be up to 0.1 Ω for I-LBA proper function.
4.7.4 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.
