What type of connector can I use to daisy chain the PN 2020 that will be spaced 6" apart?
I'm looking to buy (4) PN:2020 lights for some plant shelves I'm building. I want to daisy chain them, but the lights will be spaced 6" apart. What kind of connector can I use so I can run wire between the daisy chain connectors? Also, I don't see a transformer that will drive all four lights on your site. Do you recommend any specific model?
Our PhotonPanel product sounds like a great option for a vertical plant shelf installation. To answer your questions:
The daisy-chain "ports" utilize WAGO 2060 connectors (see here for the datasheet). For variable-length installations such as yours, we generally recommend using low-voltage wire with the maximum thickness permissible for the WAGO connectors (18 AWG).
We do not have any power supplies with sufficient capacity, but we would recommend a third-party manufacturer that has a product of sufficient capacity (we would recommend at least 500 watts for daisy-chaining 4 panels). We generally recommend Meanwell as a reliable manufacturer of power supplies, but it appears they do not have anything higher than 340 watts.
It looks like you can configure a constant current level. Should the constant current be set to 17A to match your spec sheet for four daisy chained PN:2020 panels?
The constant current feature is definitely nice to have and can work very well here to ensure stable operation. The boards are configured to operate via constant voltage without any issues, as long as the voltage level does not exceed 24 volts at any point. Even when staying at or below 24 volts, however, the actual power draw can fluctuate a bit depending on various environmental factors such as ambient temperature (higher temps = higher current draw).
If you are able to keep the current setting fixed via the constant current adjustment, that would ensure that a consistent power draw is achieved, regardless of environmental factors.
