SVBONY Power Controller SV241 Pro (ASCOM + NINA Ready)

The SV241 Pro is the “why didn’t I do this sooner?” upgrade for anyone running a serious imaging rig. It centralizes 12V power, USB connectivity, dew control, and environmental monitoring into one compact controller—so your mount, cameras, filter wheel, focuser, and heaters can all behave like they’re on the same team. Best part: it supports ASCOM and integrates with NINA, so you can monitor sensors and control outputs right from the software you’re already using.

• ASCOM driver support + NINA integration for centralized control and monitoring

• 7x 12V DC outputs with multiple controllable channels

  • Regulated interface and Switch 1–5 interfaces can be individually toggled ON/OFF

• USB port support for devices like guide cameras and planetary cameras

• Built for full rigs:

  • DC ports handle DSO cooled cameras, equatorial mounts, electronic focus controllers, motorized filter wheels, and electronic field flatteners

  • RCA interfaces are ideal for dew heaters

• Real-time temperature + humidity detection for smarter dew prevention

  • Humidity range: 5%–85% RH (T+H interface)

  • Heating tape temperature monitoring: -10°C to 50°C (Temp interface)

  • Calculates dew point and adjusts heating automatically using PWM control

• Automatic heating logic (as provided):

  • Recommended PWM ~80

  • Stops heating when the strap is ~5°C above dew point

  • Automatically resumes heating as temperature drops

• 12V / 6A power supply support for running multiple dew heaters (scope + guide scope simultaneously)

• Built-in circuit protection: reverse polarity, overcurrent, short-circuit, and ESD protection

• Automatic restart after overload to help you recover without babysitting the rig

• Intuitive status LED: steady light indicates ready/connected state

• Secure mounting with UNC 1/4-20 and M4 screw holes to reduce disconnects from bumps or movement
