- Real-time detection of ambient temperature and humidity to achieve automatic temperature control throughout the process.
SV241 Pro Astro Power Controller
If you're tired of the complexities of multiple power packs and tangled cables, the SV241 Pro power controller is the solution you've been looking for. Our philosophy was to create a compact enclosure that delivers ample current and USB data while maintaining your cables organized! Deliver power to your mount, cameras, filter wheel, and all your essential astronomy equipment, thanks to its versatile multiport design. With this astro power controller, you can fully control your astronomy eqipments.

This power box supports ASCOM drivers and seamlessly integrates with the astrophotography software NINA. Once connected, you can remotely monitor and centrally control all output ports and sensor data from the power box directly within the NINA software interface.



Each USB port outputs 5V 2.5A with 2.75A overcurrent protection; the 5V line has reverse current and short-circuit protection, independent MLCC filtering, and 15KV electrostatic discharge protection.


T+H & Temp Interfaces
Equipped with a T+H interface that collects humidity data (5%-85% RH), calculates the dew point, and controls heating; the Temp interface monitors the temperature of heating tapes in real time (-10°C to 50°C) for precise temperature control and dew prevention
Utilizing PWM technology, it achieves precise, dynamic, and automated heating control.
1.Integrating environmental data (temperature, humidity, and dew point) collected by temperature and humidity sensors and automatically adjusting the heat intensity of your Dew strips for optimal performance.
2.The 12V, 6A power supply supports driving multiple dew heaters (simultaneously powering the dew heaters of the telescope and guide scope), meeting the de-condensation needs of a full range of astronomical equipment.

Built-in Circuit Protection
Safety is paramount with the power hub, boasting a suite of protections including reverse polarity, overcurrent, short circuits, electrostatic discharge. Your astronomy devices are shielded from potential damage.In addition, this power hub provides automatic restart after overload.
Intuitive LED
A built-in LED indicator lights up steadily when ready, providing quick confirmation of device connection status.
The power box is equipped with UNC1/4-20 and M4 screw holes to meet different installation requirements and prevent loose connections and power outages caused by moving, shaking, or dropping the power supply box during astrophotography.
