QUESTION
Is an external power supply needed when using the new 700 Series DALI gateways to power up the DALI bus?
ANSWER
The new DALI gateways already have a power supply, but it is disabled by default to prevent the risk of having two power supplies at the same time in the DALI bus.
You can enable/disable the power supply with Intesis MAPS:
Consider that this parameter is enabled by default in the Intesis MAPS template.
If you are powering the bus with an external power supply, ensure to comply with the following:
- It is a DALI-2 standard power supply certified under the DiiA guidelines.
- Polarity in the DALI bus is the same for both the gateway and the external power supply.
- Be sure you are following the standard DALI guidelines for bus powering.
Remember that if the DALI bus is not powered, there will be no communication and an error will appear when testing the hardware.
