3.2.3 µ-CANSAS power supply
The imc µ-CANSAS modules are supplied via the CAN-Bus terSUPPLY and –SUPPLY ( see image in
previous section for pin configuration). The permitted supply voltage range for the imc µ-CANSAS
modules is
9 V to 50 V DC.
Note
Be aware that the total current of all connected devices flows through the CAN-Bus supply lines.
When a commercially available 6-pin cable is used, the voltage drop along the supply lines must
additionally be taken into consideration, since they have relatively high resistance (the input
voltage, measured at the module, may not be less than 9 Volts!). So, to avoid problems select a
higher power supply voltage, e.g. 24 V.
When dimensioning the current supply, note that the power-on current is higher than the long-
term current. Also make note of the information presented above on the CAN-Bus’ wiring.
imc devices' CAN-Bus terminals are not rated for the supply of imc CANSAS modules, but under
certain circumstances they can be modified at imc for this purpose. If interested, please contact
our Customer Support.
