DCDC Boost Converter — 12V (9–13V) to 13.8V, 207W / 15A, IP67 Why you need it Keeps 13.8V equipment running when vehicle or battery voltage falls below the required level. Converts a 9–13V input to a stable 13.8V output, preventing malfunction or underperformance of sensitive electronics. Delivers up to 15A (207W) continuous power for demand loads, so devices designed for 13.8V operate reliably from standard 12V systems. IP67 waterproofing and epoxy potted electronics protect the unit in harsh, wet, or dusty environments. Key features and benefits Precise boost function: Accepts 9–13V input (typical 12V systems) and outputs 13.8V for consistent operation of 13.8V devices. output capacity: 15A output current and 207W output power support demanding loads without repeated failures. conversion performance: Engineered for efficient DCtoDC conversion. The fully sealed housing also acts as a heat sink to manage thermal load during sustained use. Robust protection suite: Builtin protections for overvoltage, undervoltage, overload, overtemperature, and short circuit enhance reliability and protect connected equipment. Durable construction: Rugged aluminum housing for wear resistance and mechanical durability. Epoxy resin potting increases environmental protection and vibration resistance. IP67 rating: Dusttight and protected against temporary immersion in water, suitable for outdoor, marine, and exposed installations. Compatibility and usage Designed for 12V electrical systems (input range 9–13V). Compatible with vehicles, boats, RVs, offgrid battery setups, and other 12V sources where a stable 13.8V output is required. Works with instrumentation, communication equipment, and electronics that require a steady 13.8V supply. Practical applications Mobile communications: Power handheld or mobile radio transceivers and repeaters that require 13.8V from a vehicle's 12V battery during engineoff or lowvoltage conditions. Marine and outdoor equipment: Run navigation instruments, marine electronics, or weatherproof lighting from onboard 12V systems while exposed to moisture and vibration. Vehicle and offgrid electronics: Ensure reliable operation of invehicle chargers, control modules, or monitoring systems when alternator output or battery voltage dips. What it delivers Stable 13.8V output from varying 12V inputs Up to 15A continuous current and 207W power handling Reliable operation in harsh environments thanks to IP67 sealing, aluminum housing, and epoxy potting Multiple safety protections to safeguard both the module and connected devices Specifications (as provided) Input: 9–13V (nominal 12V) Output: 13.8V Output current: 15A Output power: 207W Waterproof rating: IP67 Housing: Aluminum Potting material: Epoxy resin Protections: Overvoltage, undervoltage, overload, overtemperature, short circuit Use this converter when you need a compact, rugged DC boost solution to maintain 13.8V equipment performance from standard 12V power sources in demanding conditions.
