AC to DC power supply for WS-12-250-DC

Tue Dec 24, 2019 6:38 pm

Hello Forum,
I have a solar sight powering a WS-12-250-DC at a remote mountain location. The station is easily accessible via snow shoes during the winter and I'm thinking about using a Goal-Zero lithium backup battery for an emergency power source. The Goal-Zero has two AC receptacles and capacity to "power a refrigerator for ~3 days". Since the WS-12-250-DC needs a DC input, what power converter could I use to connect the Goal-Zero to the netonix WS-12-250-DC to provide full functionality to the switch.

Thanks again,
AK

The -DC models were designed to be connected to batteries, and you may have problems when connected directly to a power supply instead, especially when running near the limit of the power supply.

That said, I have had no issue running them off a Meanwell SDR-240-24 and SDR-240-48 with < 150 W load on the switch.
