Anti-dew heater strip

Product Description

The anti-dew heater strip is used for anti-dew on the front window of the ASI cooled cameras.

This kit includes the zip-tie, anti-dew heater strip and an Y power cord：

The thickness of the anti-dew heater strip is 0.2~0.3mm.

The “Y” power cord is designed to connect in-line with the cooler power supply for convenience.

And we recommend a DC adapter giving 12V at 0.35 A resulting in a heating power on the strip that is around 4.2 watts. You can use one and same power cord to power both the fan and heater simultaneously, but make sure not to exceed recommended amount of Ampere.

NOTE: for many ASI-cameras a heater strip is not necessary since they have one that is build into the cameras itself.

ASI071MC-P/ASI6200/ASI2600/ASI2400 cameras come with anti-dew heater that will heat the protective glass to avoid any dew problems.

For ASI183/ASI1600/ASI294/ASI533 cameras, the heat emitting from the TEC will be conducted to the camera case and avoid any dew problems when TEC cooling system working.

How to use it?

Tear out the protective film on adhesive tape

2. Put the anti-dew heater strip on the front facing of the camera and make sure the black cable is in the right position (lining next to the DC plug at the rear end)

3. Tie the black cable with a zip-tie on the camera body.

4. Plug in the power cord, then everything is done.

Now you should be dew-free while shooting with the camera.

NOTICE: Be careful about welding portion, it is vulnerable can not holding very strong pull.

Our website is continuously updated with the most recent camera drivers as well as software for DSO and planetary imaging. Please make sure the most recent Driver and software have been installed before you start shooting:

It is also recommended to read the Manuals first before shooting.

Hi
I have a MSI533 and I am about to fit your dew band, can this be powered from my Lynx astro dew controller which gives a pulsed 12v or must it be in line withe the camera power?

  Your camera is 533 which is not necessary to use this Anti-dew heater strip.

Hello,
do I correctly understand that anti dew heater is not required for PRO versions mentioned below as internal heat emmited by TEC will avoid dew problems?

”For ASI183/ASI1600/ASI294/ASI533 cameras, The heat emitting of TEC will be conducted to the camera case and avoid any dew problems when TEC cooling system working.”

Hi there, do you have dew heaters for the 120 mini and the 224 color cameras please?

  We do not have and I think the uncooled camera does not need this.

Hi, is this needed (and compatible) for the ASI294 MC Pro in high humidity environments?
Thank you

  It can be used on ASI294MC Pro, but I will recommend you use the camera in Relative Humidity 20%~80%

Hello Sam,

I have the version 2 of the 1600MM Cooled and have been very pleased with it.
I’ve bought and attached the dew heater to it. What is the plug end specifications for it? I want to buy an adapter to my Kendrick Dew heater controller so I can regulate the amount of power like the rest of my dew heaters (on the SCT, finderscope,etc). That way I can save battery powder where possible. Thanks!

Hi Sam
I have the dew heater in my ASI 1600mm V3 and I noticed that does not feel warm when I touch it. I am using the recommend power source you sell here. Does it mean that the heater is not working?
Thank you

Hi, i would like to use it for a ZWO ASI 120 MC cooling project. Can I use it for this camera and is it possible to have the dimensions of inner and outer diameter of the heating element? Thanks in advance

Diego Gomez – April 13, 2017:

Hello there,

Dumb question: Is this heater required for any of the newest cooled cameras (for example, 071MC-C ) or just for the 1600MC/MM-Cool?

Many thanks, Diego

  this is just for 1600, but if you can use it if you have such problem with 071

Hi Sam
I have the 1600MM Cool and suffer from the dewing problem.
I have the Mini EFW attached but use no spacers. I have perfect focus.
If I use the dew heater, is this likely to effect my focus?
I certainly do not understand what the extra spacers are for.?

- Sam Wen – April 14, 2017:
  
  the extra spacers are allowed to adjust the angle of the sensor
  you don’t need it if you have perfect focus

Hi Sam
Could you explain a bit more about the power requiriments? You mention 12v 0.35A. If connected the cámara and the heater to the power source you selll (12v 5a) then you have 3a left. Would this damage the heater theb which only needs 0.35a?
Thank you

  no, it need only 0.35A
  just make sure the power supply can provide enough current >0.35A

“And we recommends 12V at 0.35A DC adapter where the heating power on the strip is ~4.2 watts. You can use one and same power cord to power both the fan and heater simultanously, but make sure not to exceed recommended amount of Ampere.”

I power my camera with a 2amp 12volt power supply when on 110volt electric. Will this be too much for the dew heater to handle and burn it out…or is that OK? When in the field running off a 12 volt battery, I assume this won’t be an issue as the AMPs are lower.

  no, this heater only need 0.35A, the power supply just need to be higher than this

Strange.
You we put on the market a crude product.
Then you issue completions. Paid.
What engineers receive the money for?

Thanks!

Sam – I don’t understand the purpose of the 2 spacers. Are they necessary if attaching to the ZWO EFW 8 filter wheel?

Thanks,

  no, this is not necessary

Hi Sam
Is the anti-dew heater necessary for the ASI 1600 cooled mono version 3, considering the new mechanical improvements?
Thank you

  this depends on the humidity, I think 100% humidity still need the anti-dew heater
