This DC power converter steps down a higher DC voltage to a stable 12V output, designed as an onboard module that directly integrates into 24/36/48/72V systems. It is rated to deliver up to 20A from inputs in the 1590V DC range, making it suitable for a wide variety of 12V load applications. Key benefits Enables 12V devices to run reliably from higher voltage sources without separate adapters. Wide input compatibility: 1590V DC support, including nominal 24/36/48/72V systems. Onboard module for easy integration into existing electrical setups and projects. current capability: up to 20A output to support midrange 12V loads. Compact form factor suitable for compact installations and spaceconstrained panels. Key attributes Functionality: DCDC stepdown converter on an onboard module. Output: 12V DC. Input range: 1590V DC. Nominal input options referenced in the listing: 24/36/48/72V. Current rating: 20A (continuous). Package: 1 piece per . Physical characteristics: Onboard design; exact dimensions and enclosure material are not specified in the listing. Performance note: Designed to deliver a stable 12V output from highervoltage DC sources within the stated range. Use cases 1) Automotive, industrial, or solar installations where a 24/36/48/72V DC bus feeds 12V devices such as sensors, cameras, or control electronics. 2) Battery and power systems (e.g., solar or wind) that require a 12V local supply for auxiliary hardware while the main system operates at 1590V DC. 3) DIY projects or prototyping that demand a compact, onboard 12V power source from a highervoltage DC source with up to 20A load. Notes This description reflects the product's stated specifications: 24/36/48/72V to 12V DC stepdown, onboard module, 1 piece, input range 1590V, and 20A current rating. Exact dimensions and enclosure material are not provided in the listing; the unit is described as an onboard module suitable for integration into compatible systems.
