Pegasus Astro - Saddle Powerbox
Visit Pegasus Astro Saddle Powerbox is a versatile accessory designed to make any astronomy or astrophotography set-up simpler and more reliable.
It combines a mounting saddle (Losmandy & Vixen) and a intelligent power station, This allows you to power cameras, mounts, heaters, accessories and computers, while drastically reducing cable clutter.
Thanks to its USB ports, numerous 12V outputs, integrated sensors and comprehensive control software, the Saddle Powerbox secures your setup, avoids blackouts and guarantees optimum management of your observation nights.

6 12V power supply outputs
The Powerbox features 4 standard 12V outputs and 2 PWM outputs for heating resistors (convertible to fixed 12V outputs). Internal MOSFETs provide a stable, reliable power supply. The 4 main outputs switch on and off together, while the two PWM outputs can be controlled individually.
Integrated sensors
The Saddle Powerbox continuously measures temperature and thehumidity for optimal monitoring of ambient conditions and automatic mist control.
It also displays the input voltage and the current drawn.
Heating resistors (2 ports)
Two PWM outputs provide precise control of your heating elements, with a capacity of 5A per output.
The function Auto-Dew automatically adjusts power output according to dew point.
Two adapters DC 2.1 → RCA are included.
Power consumption monitoring
An internal ammeter measures the total consumption of your setup. You can monitor voltage and current in real time to avoid overloads.
Over 10A of available current
Designed for demanding setups, the Powerbox can supply up to 10A in total.
A typical photo installation consumes between 5 and 7A.
