SVBONY SV241 Astronomy DC and USB Hub Box

Product Overview

The SVBONY SV241 is a compact power and USB distribution box for a telescope imaging rig. A single 12V DC input (5.5 x 2.5 mm, 10A) feeds six 12V straight-through DC outputs (5.5 x 2.1 mm), and a built-in hub provides two USB 3.1 Type-A data ports, one USB 2.0 Type-A data port, two USB 2.0 Type-A power-only ports and a USB Type-C port. The hub connects to your computer over USB Type-B. The body measures 96 x 61 x 25 mm, weighs 125 g, and mounts by a 1/4″-20 UNC thread or two M4 holes 20 mm apart.

Who It's For

This is a good match if your imaging setup has a camera, mount, focuser, filter wheel and dew heaters each running its own power and data cable, and you want one box on the telescope that gathers them into a single power lead and a single USB cable to the computer.

Key Features & Design

• Six 12V DC outputs: straight-through 5.5 x 2.1 mm ports for cameras, mounts, dew heaters and other 12V devices, with 12V 10A total DC capability.
• USB hub: 2 x USB 3.1 Type-A data, 1 x USB 2.0 Type-A data, 2 x USB 2.0 Type-A power-only and 1 x USB Type-C, with 5V 8A USB power capability.
• Protection: ESD, reverse-polarity and filter protection, plus over-voltage, over-current and short-circuit protection on the USB ports.
• Power indicator: a red LED shows the unit is powered.
• Mounting: 1/4″-20 UNC thread and 2 x M4 holes (20 mm spacing) for a dovetail, tube ring or tripod.

Recommended Uses

• Deep-sky imaging rigs: power and connect the camera, mount, guide camera, focuser and filter wheel through one box.
• Cable management: mounted on the telescope, it shortens cable runs and reduces snag points as the mount slews.
• Field setups: the included cigarette-lighter cable runs it from a 12V vehicle or battery socket.

Compatibility and Accessory Notes

• DC devices: SVBONY lists astronomy cameras, camera angle adjusters, computers, equatorial mounts and dew heaters.
• USB devices: astronomy cameras, camera angle adjusters, electronic focusers, computers, equatorial mounts, OAG cameras and filter wheels.
• Power input: 12V DC via a 5.5 x 2.5 mm plug, 10A maximum.
• Not weatherproof: SVBONY lists it as not waterproof, so it is best kept under a cover in dewy conditions.

What's in the Box

• 1 x SV241 Micro DC + USB HUB Box
• 1 x USB Type-B to USB Type-A cable, 39.4″
• 1 x DC 2.1 to 2.1 male power cable, 19.7″
• 1 x DC 5.5 x 2.5 cigarette lighter power adapter cable, 59″
• 1 x User manual

Good to Know Before You Order

• Input limit: SVBONY specifies that input above 12V 10A blows the internal fuse and leaves the unit unusable, so a regulated 12V supply sized to your load is the right source.
• No software control: outputs are straight-through, without switching or dew-heater regulation. The SV241 Pro adds those functions.
• Power supply sold separately.
• This listing is the single SV241. SVBONY also lists two-unit and heater bundles on its page.

Frequently Asked Questions

Is it difficult to set up?

No. Mount it on the telescope, connect a 12V supply and the USB Type-B cable to your computer, then plug each device into the DC and USB ports. No driver is listed for it.

Can it power a cooled camera?

The DC outputs share the 12V 10A input, so a cooled camera can run from it as long as the total load of all connected devices stays within 10A.

Do I need USB 3 for my main camera?

The two USB 3.1 ports suit imaging cameras; the USB 2.0 ports suit guide cameras, focusers and filter wheels.

Can I control the outputs from software?

No. The SV241 is a passive distribution hub; switching, adjustable voltage and dew control are features of the SV241 Pro.

Bottom Line

In short: a 125 g telescope-mounted hub that gathers six 12V DC outputs and a six-port USB hub into one power input and one USB cable, with ESD, reverse-polarity and USB overload protection.
