What kind of power supply do I need for the SVBONY SV192 Dew Heater Strip?
You will need a 12V DC power source with a female 5.5x2.1mm connector. This is a common standard for portable astronomy power tanks, field batteries, and AC-to-DC adapters.
How much power does the SV192 Dew Heater draw from a battery?
The SV192 draws 1.7A ±0.1A. For planning purposes, if you have a 17Ah battery, this heater running at full power would theoretically last about 10 hours. Your actual runtime will vary based on battery health and other connected equipment.
Is the temperature of the SVBONY SV192 adjustable?
Yes, the SVBONY SV192 features adjustable temperature. This requires a separate dew controller (not included) that can regulate the voltage or use pulse-width modulation (PWM) to control the power output, allowing you to fine-tune the heat and conserve battery life.
What size telescopes will the SVBONY SV192 Dew Heater Strip fit?
The fit depends on the outer diameter of your telescope tube or dew shield. To ensure a proper fit, you should measure the circumference of the part you intend to heat. This strip is typically suitable for small-to-medium refractors, camera lenses, and finder scopes.
I'm using an 8" SCT for a long night of imaging the Andromeda Galaxy (M31). Will the SV192 keep my corrector plate clear?
While the SV192 can provide heat, its suitability for an 8" SCT corrector plate depends on its physical length. You should measure the circumference of your SCT's front cell. If the strip is long enough to wrap around it, its 19.2W-21.6W output is generally sufficient to prevent dew on a corrector of that size in most conditions.
Can I use the SVBONY SV192 on my 80mm refractor's dew shield and my guide scope?
Yes, the SV192 is well-suited for use on the dew shields of 80mm-class refractors and most standard 50mm or 60mm guide scopes. Its power output is ideal for preventing dew on these smaller optical elements without introducing tube currents.
