Celestron Smart Power and Dew Control 4x
The Celestron Smart Power and Dew Controller 4x is a full power hub for larger imaging setups. It combines four automatically regulated dew-heater channels with fixed and variable 12 V outputs and powered USB ports.
Smart dew control
Four RCA dew-heater ports each have a matching thermistor port for temperature-based regulation. You can control it from CPWI or from a compatible Celestron hand controller over the AUX ports.
Power and USB hub
An XT60 high-current input accepts up to 20 A (240 W total). Three fixed 12 V outputs are rated at 7 A each, and a variable output adjusts from 3 to 12 V at up to 5 A. Three USB Type-A ports supply up to 2.5 A each, and the PC connection is USB 3.2 Type B.
