TS-Optics USB Dew Heater with Control for 70-90 mm Dew Shield Diameter

TS USB Dew Heater Strap

Who doesn´t know the problem: The night is cool and clear, but unfortunately a bit humid. The humidity condenses on the optics and ends the observation or astrophotography prematurely. Heating bands are the right remedy against this.

Heating straps or heating bands are simply placed around the dew shield at the height of the optics and fixed with the flexible Velcro tape. Since the straps are insulated to the outside, the heating power is directed inward, toward the optics. The minimal heating prevents the precipitation of humidity.

The power supply of the TS USB dew heaters

The heaters have a USB plug and can be supplied with energy via a power tank or a power bank. The heaters require an operating voltage of 5 volts. Please do not connect the heater to the USB port of your computer. The USB port is not designed for this and it can be destroyed.

Question:
Is the power higher when the regulator is left out??


Answer from Teleskop-Service:
When the controller is set to full power, the power is at almost 100%. The regulator itself only needs about 2%. Without the controller, the dew heater strip always runs at 100%. So we recommend to always run with controller to regulate the dew heater strip. It is only important that the controller is connected correctly: "Input" to the power source, "Output" to the heating cuff.
