LORDWORLD

LORDWORLD 2pcs Waterproof DC Buck Converter 8V-22V to 3V-15V 3A Adjustable Regulator Module

SKU CH-FRDN-AXJYV

Waterproof buck converter steps 8 V–22 V input down to 3 V–15 V at up to 3 A with built-in protection

  • Waterproof sealed enclosure protects against moisture and dust
  • Adjustable 1 V to 15 V output suits many low-voltage projects
  • 3 A peak current with 2 A continuous rating for reliable loads
  • Built-in reverse, over-current, over-heat and over-voltage safeguards
  • Bottom-mounted potentiometer allows precise tuning without accidental shifts

Waterproof buck converter pair

This pack contains two LORDWORLD DC buck converter modules that step down an input voltage between 8V and 22V to an adjustable output of 1V to 15V. Each unit handles up to 3A peak current and is designed for hobbyists who need reliable voltage regulation in damp or dusty environments. The fully sealed enclosure doubles as a heat sink for passive cooling.

Build integration and constraints

The modules require a DC source at least 3V higher than the desired output and accept 8V to 22V from batteries, vehicle systems or bench supplies. A bottom-mounted potentiometer allows precise voltage trimming with a small screwdriver while resisting accidental shifts once installed. Built-in reverse-connection, over-current, over-heating and over-voltage protections reduce the risk of damage to downstream circuitry.

What the bundle changes

Supplying two identical regulators lets you power separate subsystems — such as a radio and an LED display — from one input rail without cross-loading. The matched pair simplifies spares management and ensures consistent protection behaviour across both channels in automotive audio, motor control or portable electronics projects.

Questions about this item

At what output current does the converter need extra heat sinking for continuous use?

Above 2 A continuous output the module requires additional heat dissipation; at or below 2 A the sealed enclosure is sufficient.

How hot or noisy does the sealed enclosure get during all-day operation?

The potted case acts as a passive heatsink and contains no fan, so it runs silently and stays warm but within safe limits at rated load.

What input voltage source must I already have to power this module?

A DC supply between 8 V and 22 V that can deliver at least 3 V more than your desired output voltage.
