Grey rectangular DC-DC converter module with aluminium housing and cable leads

KEHIPI

KEHIPI 48V 36V to 12V 240W 20A DC-DC Step-Down Converter IP67 Waterproof Power Adapter

SKU CH-E5F4-Y6DXP

Converts 30-60 V DC input to a fixed 12 V, 20 A output with 96 % efficiency and IP67-rated aluminium housing

  • Product typeDC 12 V*20A (48 V-12 V)
  • Product colorGrey
  • Product weight0.28 kg
  • Converts 36V or 48V input to stable 12V output for sensitive electronics
  • Delivers 240W at 20A continuous current for demanding 12V loads
  • Achieves 96% conversion efficiency reducing heat and extending battery run-time
  • IP67 aluminium housing resists water, dust, shock and humidity in harsh environments
  • Operates reliably from -40°C to 80°C with built-in overload, over-temperature and short-circuit protection

36V/48V to 12V 240W Converter

This KEHIPI step-down converter reduces a 30V to 60V DC input to a fixed 12V output at 20A, delivering up to 240W. It uses synchronous rectification for 96% efficiency and includes an upgraded fuse and end-clamp terminals. The IP67-rated aluminium shell is sealed against water, dust, shock and humidity. It operates reliably from -40°C to 80°C.

Suits 12V loads on 36V or 48V systems

Ideal for powering 12V accessories such as LED strips, car audio, monitors or radio gear from golf-cart, scooter, truck or solar batteries. The built-in protections cover over-load, over-current, over-temperature, short-circuit and over-voltage. Not suited for buyers who need an adjustable output voltage, a step-up topology, or an input range outside 30V to 60V.

Fixed 12V 20A output decides fit

The single specification that determines compatibility is the fixed 12V 20A (240W) output. Your load must not exceed 20A continuous draw, and the source must stay within the 30V to 60V input window. No other output voltage or current setting is available on this module.

Questions about this item

How do I wire the DC 30-60V input and 12V 20A output without reversing polarity?

Connect the input leads to a 36V or 48V source within the 30-60V range, then attach the output leads to the 12V load; the built-in fuse and end clamps help prevent a reversed connection.

What part will need replacement first if the converter runs at full 240W load continuously?

The internal fuse is the primary sacrificial component; it will open before the MOSFETs or capacitors degrade under sustained 20A output.

At what temperature does the thermal protection activate during extended high-power operation?

The converter shuts down when its internal temperature reaches 185°C, then restarts automatically once it cools below that threshold.
