What type of DC power source is used by the DE units?
DE19B & DEPC are powered through a 2.1mm Power Jack Connector. The power requirements are 6Vdc, 300ma per unit. Actual consumption would be less, but due to changes in consumption based on attached accessories as well as flucuations due to processing, we recommend dedicating 300ma per unit. In addition the onboard power regulator can handle up to 9Vdc, but this would cause additional heat within the unit, we recommend keeping it at 6Vdc. To source this from a DC supply you would need to locate the proper 2.1mm connector, we purchase power supplies with this already attached, we do not carry just the connector.
