NETWORK POWER SUPPLY

9.1

Power segments

Calculate the overall power consumption of all the devices in the network. Build power segments with a

maximum load of 100 W. This refers to the M12 connector (A-coded). This component has a current limit of

approx. 4 A.

9.1.1

One power segment

In a network with one power supply, overall power consumption is limited to 100 W.

Additional power supply

For higher power consumption, use additional power supplies and Y-connectors with interrupt to utilise

power from a second power supply.

Rule of thumb

The rule of thumb is that 1 W load per metre results in a voltage drop of 1 mV. A maximum voltage drop of

5 V is allowed. Some devices will shut down if the supply voltage is lower than 19 V. Therefore, refer to the

respective data sheet for more information.
