legs, tighten the strap with the buckle, and secure the strap end
to itself with the hook-and-loop fasteners on the strap (Figure 6).
- If your tripod's accessory tray is large enough, you can place the
controller on the tray. If you choose this method, keep in mind that
the controller will not be secured in place. Be careful to avoid
forceful cable pulls.

NOTE: DO NOT PLACE THE CONTROLLER ON THE GROUND!
Water and dirt can potentially enter the controller and may cause
electrical problems.
USING THE BRIDGE FOR CABLE MANAGEMENT
The bridge on the enclosure houses the controller's environmental
sensor, isolating it from radiant heat to provide the most accurate
ambient temperature and humidity data. We also designed the bridge
to help with cable management. You can run cables underneath the
bridge to keep them captive and organized (Figure 7). Simply insert
the cable end underneath the bridge and pull it through until there is
enough slack to connect the cable's plug to the corresponding port
on the controller.

4. Powering the Controller

You will need a suitable 12V DC power supply for the Smart
DewHeater and Power Controller 4x. The appropriate power supply
will depend on the equipment you have plugged into the controller.

The maximum power the controller can deliver is 240W (20A max
current @ 12V DC), but many use cases require less power. Before
choosing a power supply, determine the approximate amount of
power needed for your setup and how much battery capacity you'll
need for your observing session.
Helpful formulas:
- Voltage (in Volts) x Current (in Amps) = Power (in Watts)
- Current (in Amps) x Time (in hours) = Battery current capacity
(in Amp-hours) required

The maximum input voltage for the power input jack is 13.8V DC.
Make sure your power supply's output voltage does not exceed this.
If more than 13.8V DC is supplied, all output ports will automatically
shut off to protect the circuitry, and the "Over Voltage" status LED on
the enclosure's bridge will blink.
Choose from the following power options:
- For up to 120W power (10A max current), the Celestron PowerTank
Lithium Pro or Celestron PowerTank 17Ah is a great choice. Using
the power cable supplied with the controller, connect the cigarette-
lighter plug to the battery and the XT60 connector to the controller
(Figure 8).

You can use the included power cable to connect a battery to the controller.
- If you are running high loads from a portable setup, consider a 12V
DC "marine battery" from a third-party vendor. These batteries
can easily provide 240W (20A @ 12VDC) and have enough
capacity to run your setup all night. You may need to connect
directly to the battery's terminals using a battery terminal-to-XT60
adapter (not supplied).
- If you do not need to be portable, connect to an AC power outlet
using an AC-to-12V DC adapter. If your setup requires 60W power
or less (5A current or less), you can use Celestron's AC Adapter-
5A. Connect the adapter's output cable to the controller's barrel
connector power input jack, thread the connector to the exterior of

with more capacity than the PowerTanks to run your setup
all night.
