To ensure proper function:
It is strictly recommended to use power supply cable 2,5mm
2
!
Maximum continuous DC power supply voltage is 36 VDC. The
InteliNano
NT
’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 devise should be used.
For the connections with 12VDC power supply, the
InteliNano
NT
includes internal capacitors that allow
the controller to continue operation during cranking if the battery voltage dip occurs. If the voltage
before drop is 10V, after 100ms the voltage recovers to 5 V, the controller continues operating.

RECOMMENDED POWER SUPPLY WIRING
The capacitor size should be 5 000
µF to withstand 150ms voltage dip under following conditions:
Voltage before the drop is 12V, after 150ms the voltage recovers to min. allowed voltage, i.e. 8V.
