It delivers a total of 10A of power through four software-switchable 12V outputs and two 4A PWM channels for dew control. An onboard USB hub with two USB3.1 and two USB2 ports, combined with a built-in environmental sensor accurate to ±0.5°C, consolidates your entire imaging rig's infrastructure into a single, cable-managed unit.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eDual Losmandy\/Vixen Saddle: A 40kg \/ 88 lbs Payload Capacity Platform\u003c\/h3\u003e\n\u003cp\u003eAt its core, the Saddle Powerbox is a high-capacity mounting platform designed for stability and universal compatibility. The saddle accepts both the wider Losmandy D-style plates and the narrower Vixen V-style plates, eliminating the need for adapters. With a supported weight of 40kg (88 lbs), it provides a rigid foundation for heavy optical tubes and fully-loaded imaging trains, ensuring your setup remains secure throughout the night.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003e10A Power Distribution: 4 x 12V and 2 x PWM Outputs\u003c\/h3\u003e\n\u003cp\u003eThis device simplifies field power management by centralizing all your 12V equipment. It features four 12V DC outputs that share a total maximum current of 10A, perfect for powering your mount, camera, and other accessories from a single source. Two additional, dedicated PWM channels can each supply up to 4A, allowing for precise, software-controlled regulation of dew heater strips to prevent moisture buildup on your optics.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSoftware Control:\u003c\/strong\u003e Every 12V port can be switched on or off through the Pegasus Astro Unity Platform software, giving you remote control over your entire rig.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlexible Outputs:\u003c\/strong\u003e The two PWM channels can also be configured to function as standard, constant 12V outputs if you don't require dew control.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eIntegrated USB 3.1 Hub: 2 SuperSpeed and 2 High-Speed Ports\u003c\/h3\u003e\n\u003cp\u003eCable drag is a primary source of tracking errors and connection failures. The Saddle Powerbox places a 4-port USB hub directly on your telescope, reducing the number of cables running back to your computer to just one. Two USB3.1 SuperSpeed ports provide the bandwidth needed for modern, high-resolution CMOS cameras, while two USB2 High-Speed ports are ideal for your mount, guide camera, or electronic focuser.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eEnvironmental Monitoring: Sensors for ±0.5°C Accuracy and 5-15V Input\u003c\/h3\u003e\n\u003cp\u003eIntegrated sensors provide critical data about your observing conditions and power supply. An onboard sensor measures ambient temperature with ±0.5°C accuracy and relative humidity, allowing the control software to calculate the dew point and automatically manage your heaters. A built-in voltmeter monitors the input voltage from 5V to 15V, alerting you if your field battery is running low before it impacts your session.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eSaddle Powerbox vs. A Separate Saddle and Powerbox\u003c\/h3\u003e\n\u003cp\u003eWhile using separate components allows you to mix and match brands, the integrated design of the Saddle Powerbox offers a clear advantage in efficiency and cable management. A traditional setup requires a saddle, a separate powerbox mounted nearby, a USB hub, and a web of power and data cables connecting them all. The Saddle Powerbox consolidates these three devices into one unit, drastically reducing cable clutter, minimizing potential points of failure, and creating a cleaner, more balanced, and faster-to-deploy astrophotography rig.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eWhat types of dovetail plates are compatible with the Saddle Powerbox?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eThe Saddle Powerbox features a \u003cstrong\u003edual saddle design\u003c\/strong\u003e, making it compatible with both the 3-inch \u003cstrong\u003eLosmandy (D-style)\u003c\/strong\u003e plates and the 1.75-inch \u003cstrong\u003eVixen (V-style)\u003c\/strong\u003e plates without needing any adapters.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eWhat is the total power output of the Saddle Powerbox?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eThe unit can deliver a \u003cstrong\u003emaximum electric current of 10A\u003c\/strong\u003e in total.
