Key benefits Provides a stable, regulated 12 V DC supply from a wide range of DC sources (9–36 V). Keeps sensitive electronics operating correctly when input voltage varies. Isolated output prevents ground loops and reduces noise, protecting downstream equipment and improving system reliability. 20 A continuous output capacity supports powerhungry 12 V loads without needing multiple converters or complex wiring. What this product does Converts an input DC voltage between 9 V and 36 V into a regulated 12 V DC output. Provides galvanic isolation between input and output to separate grounds and reduce interference. Delivers up to 20 amps of continuous current for 12 V devices. Who needs this and why Anyone powering 12 V loads from variable DC sources (automotive, marine, solar battery banks, or industrial systems) will benefit from a reliable, isolated 12 V supply. Useful where ground separation is required to avoid interference, protect measurement systems, or prevent unwanted current paths between subsystems. Helps consolidate power distribution by providing a single dependable 12 V rail for multiple devices. Key attributes Functionality: DCtoDC isolated voltage conversion with regulated 12 V output and 20 A current capacity. Compatibility: Accepts 9–36 V DC input. Suitable for 12 V equipment and electronics that require a regulated 12 V supply. Performance: Capable of supporting current 12 V loads up to 20 A continuously. Form factor and installation: Designed for panel or chassis mounting and wiring into existing DC power systems (confirm mounting and clearance requirements during installation). Durability and safety: Isolation improves safety and system resilience by separating input and output grounds; follow standard wiring, fusing, and ventilation practices. Typical applications Mobile and vehicle systems: Power onboard 12 V devices (radios, pumps, lighting, control modules) from vehicle alternator/battery sources with variable voltage. Solar and battery installations: Create a stable 12 V rail for inverters, charge controllers, or monitoring equipment when source voltage varies with charge state. Industrial control and instrumentation: Supply isolated 12 V power to sensors, data acquisition modules, and control electronics to prevent groundloop interference. Installation notes and practices Verify input voltage is within the specified 9–36 V range before connecting. Use appropriately rated wiring and a fuse or circuit breaker sized for the 20 A maximum output and inrush characteristics of connected devices. Provide adequate ventilation and mounting clearance; avoid enclosing the converter in a way that traps heat. Connect input and output grounds according to system design—remember that output is isolated and may require a deliberate ground reference if needed by downstream equipment. What to check before Confirm your source voltage falls within 9–36 V. Confirm your load requires 12 V and does not exceed 20 A continuous. Determine any grounding or isolation requirements for your system that would benefit from an isolated converter.
