Dew Controllers

These dew controllers will soon be discontinued.  I have (1) red two channel dew controller left (2Channel-2S).  Once they're gone, they're gone!

Also, I modified the remaining dew controller so that it can accept the attachments I make for the powerbox brackets, such as an LSaddle that will clamp onto a Losmandy dovetail bar.  So you can mount this dew controller cleanly on a Losmandy or Vixen dovetail bar, or even in a Synta shoe.  After your order is placed I will contact you regarding what attachment you would like.

Just as the name implies, I have developed a line of simple dew controllers that will meet the dew prevention needs of the home astronomer. 

Available in multiple configurations and colors.

Each port of these 2 or 4 channel dew controllers can supply a maximum of 5A which is more than adequate for even the most demanding dew straps on the market.  Both the controller and power supply are each fused at 10A.*
