Hi,

Does any one know the max DC power consumption for the ES-450 modem?  
The user guide listed 100–240 VAC, 50/60 Hz, 500 mA, but no DC power info.

Thanks.  
CF

Hi,

Well, the User Guide does indicate 9-36 V draw is supported for the ES, and that the AC power supply has an output of 12V @ 1.5A

Cheers
