Thousand Oaks Digital Dew Heater Controller
Comprehensive Dew Protection Solution
From astronomy systems simple to complex, the Thousand Oaks Digital Dew Heater Controller has you covered! With support for up to 4 RCA dew channels this single controller can precisely power four dew heater bands to provide ample coverage for your optics. Shield your system from dew with this mighty heat distribution solution!
When it comes to protecting your view from the contrast and detail destroying
effects of dew, the Thousand Oaks Digital Dew Heater Controller provides you
with plenty of coverage! With four channels you can realize more complex or
complete dew protection than dual channel controllers can provide; able to
cover not just the main and finder optics, but also each scope's eyepiece in a
typical observing setup. These channels are backed by PWM control for a more
consistent and intelligent adjustable power output compared to simple
resistive systems, giving you the ability to provide more targeted and
reliable dew protection based on each channel's needs. In addition to four
adjustable outputs this controller features a non-adjustable 12V DC output
port for powering an auxiliary device in addition to your dew protection
solutions*. All outputs are the dew heater standard RCA connection for wide
compatibility, and are powered via the 5A fuse protected 12V DC cigarette/car
style adapter. In addition to the replaceable fuse, the Thousand Oaks Digital
Dew Heater Controller features reverse polarity and lead-acid battery
discharge protections to protect your sessions on two fronts. Thousand Oaks
has also included small quality of life touches like a generous 12' power
cable, printed adjustment guides, green system status LED, and four red
channel LEDs, that make setting up and using this controller easy!
*Auxiliary output voltage may deviate slightly when large dew heater bands
are used on low power
Shield Your System From Dew
With four adjustable dew heater outputs backed by a number of system protections, the Thousand Oaks Digital Dew Heater Controller keeps moisture from interrupting your night!
Four Adjustable Outputs
To provide comprehensive
system protection the Thousand Oaks Digital Dew Heater Controller supports
up to four dew heater solutions! Each RCA port is individually adjustable
with a simple knob, featuring a printed adjustment range guide and status
LED for quick and easy to understand visual feedback of your dew control
status. This adjustable power output ranges from 0-100% and uses
microprocessor driven PWM control to keep your power output more consistent
than a purely resistive solution which may be prone to change with
variations in temperature and humidity.
More Than Just Dew Protection
The Thousand Oaks
Digital Dew Heater Controller protects your dew heating solutions in
addition to your optics! A combination diode and fuse system helps prevents
reverse polarity and shorts from damaging your equipment; with the 5A fuse
itself being replaceable*. For users powering their controller of a 12V
lead-acid battery or their car's cigarette/ accessory port, this controller
features an additional protection with its intelligent low voltage cutoff!
With this feature enabled, the Thousand Oaks Digital Dew Heater Controller's
green status LED will begin to flash when 11.25V is detected. The unit will
then shut itself down after 15-60 minutes (time dependent on number of bands
in use) or when the voltage drops below 11V, whichever comes first. This
helps> prevent deep discharges which can harm your battery or leave
your car stranded!
*Do not replace the fuse with one rated higher than 5A
