I have the HT2000W router set up off the power grid in a physically challenging (access, space, etc.) environment. Power is derived from DC solar and batteries. It dawned on me that the power currently goes from DC, to a third-party AC converter, to the router plug, which is then converted back to DC for the router. This DC to AC to DC conversion is a waste of power and space and considerably complicates the system. In another posting, I read the below:
"I use only dc. Is there a way to connect the modem directly to a dc source of power?" No. the power brick produces several DC voltages from the AC source. I have not taken a volt meter to determine what they are in this particular instance, but the common power brick usually produces anywhere from 3 to 6 various DC voltages that range from -/+5vdc to -/+48vdc. and are used for isolated purposes within the equipment. It might even pass 120VAC through to the modem in addition to the DC. As I said, I just haven't checked to see what it is providing.
How would I go about removing the AC part of the power supply?
Though a rep will have to confirm this, the power brick that is supplied with the HughesNet modem must be used with that modem, and as is.
The brick powers not just the modem, it also powers the transciever on the dish via the cabling. Best not to experiment since both are extremely voltage sensitive.
Also, as an aside, power conversion via AC and tapped step-down transformers are a lot more efficient than DC.
