A smart function exists in the controller’s firmware: The controller can consult the environmental readings of
the
dew point and automatically adjust power of the Dew Heaters. This functionality can be switched on / off from the
software.
Please notice: Dew heater outputs are suitable for a flat panel also.

Each output (4 x 12V + 2 x Dew Heaters) has an individual current meter. Smart Mosfets are capable to diagnose the
power consumption of each port and provide protection against overload, over temperature and short circuit.
A DC voltmeter is installed after controller’s power input.

STEPPER MOTOR CONTROLLER
A stepper motor controller will move your focuser with absolute positioning. Backlash compensation is implemented
in the firmware and can be enabled, tuned or disabled from the supplied software. An ASCOM6 focuser driver is
available.
Controller can drive
unipolar
stepper motors. Can support max 1.6 Amps (
0.8 Amp per phase
). An auto-recovery
PTC fuse is installed inside the controller to avoid any overcurrent issue with the connected stepper motors.
An RJ12 connector is located at the back of the Ultimate Powerbox. Pinout can be seen at the following table:
