From a single 12V DC input (10A max) it supplies one always-on 12V output, five individually switchable 12V outputs (6A max each), a regulated 0–15V adjustable output (3A max), two PWM-controlled RCA dew heater ports, and a USB hub with two USB 3.0 and four USB 2.0 ports. It connects to your computer over USB 3.0 Type-B, runs under ASCOM with NINA integration, and reports voltage, current, temperature and humidity. The housing measures 100.5 x 87.5 x 24.5 mm and weighs approximately 210 g.\u003c\/p\u003e\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0686\/0049\/6239\/files\/2_20260720150459_0184.webp?v=1791667878\" alt=\"SVBONY SV241 Pro remote control of outputs and sensors in NINA\" style=\"max-width:100%;height:auto;\"\u003e\u003c\/p\u003e\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0686\/0049\/6239\/files\/1600x837-8_20250902135518_2041.jpg?v=1791667879\" alt=\"SVBONY SV241 Pro NINA software control panel\" style=\"max-width:100%;height:auto;\"\u003e\u003c\/p\u003e\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0686\/0049\/6239\/files\/1600x837-3_20250826191326_5973.jpg?v=1791667878\" alt=\"SVBONY SV241 Pro switchable 12V and adjustable outputs\" style=\"max-width:100%;height:auto;\"\u003e\u003c\/p\u003e\u003ch3\u003e\u003cstrong\u003eWho It's For\u003c\/strong\u003e\u003c\/h3\u003e\u003cp\u003eThis is a good match if you run a computer-controlled imaging setup — cooled camera, mount, focuser, filter wheel, guide camera and dew heaters — and want power, USB and dew control in one box on the telescope, switched and monitored from your capture software.
