Hi Steve; the requirements vary depending on the model but the # DMC94RR uses 12V power with an amperage of 7.5A. Your converter only needs to be able to handle the 7.5 amp draw from the furnace. The smallest we have is a converter charger like the # PD49RR which is 30A but you're going to need a battery to go with it. Alternatively you could add a full power center like # PD4045KA. The converter output is quite a bit higher compared to your requirement but that gives you room to add something later like lights.
