The 60V72V(18 90V) to 13.8V 15A DC converter step down waterproof power module provides a reliable way to convert a wide DC input to a stable 13.8V output with a current capacity up to 15A. Designed for rugged outdoor and vehicle environments, this module accepts a broad input range and delivers a regulated 13.8V suitable for powering 13.8V electronics, charging circuits, and accessory loads from higher voltage sources. Key benefits Wide input range for flexible application: accepts 18 to 90V DC, covering 60V and 72V nominal systems as well as other DC sources. Stable 13.8V output at up to 15A: provides a consistent voltage to power or charge 13.8V devices and systems from a higher voltage supply. Waterproof construction: designed for outdoor, exposed, or harsh environments where moisture protection is required. Compact power module for integrated use: a self contained DC DC buck converter suitable for embedding in enclosures, vehicles, or equipment bays. Simple integration: converts a voltage DC source directly to a fixed 13.8V output, reducing the need for multiple regulators or custom wiring. Key specifications and attributes Input voltage: 18 90V DC (60V/72V nominal systems supported) Output voltage: 13.8V DC Output current: up to 15A Type: DC converter step down (buck) power module Construction: waterproof power module designed for outdoor or exposed installations Functionality: converts higher DC voltage to a stable 13.8V suitable for powering or charging DC loads Compatibility: intended for use with higher voltage DC systems that require a 13.8V output Two to three use cases Electric vehicle or fleet applications: draw 13.8V from a 60V or 72V battery pack to power onboard electronics, sensors, or auxiliary charging circuits without multiple regulators. Solar or voltage DC charging setups: use the module to derive a steady 13.8V for 13.8V batteries or devices from a higher voltage array or storage bank (ranging up to 90V input). Outdoor equipment and marine installations: supply a reliable 13.8V supply to instruments, lighting, or communication devices from a rugged, waterproof source in exposed environments.
