KEHIPI BZONE-PC12-30A 18-60V to 12V 30A 360W DC-DC Buck Converter Power Adapter

SKU CH-WWCE-HYKKV

Steps 18-60 V input down to 12 V at 30 A with 95 % efficiency and full protection in a waterproof aluminium case

  • ColorGrey
  • Delivers 360W at 12V 30A for high-power accessories
  • Accepts 18V to 60V input across 24V 36V 48V systems
  • Smart-chip protection guards against over-current over-load short-circuit over-heat
  • 95% synchronous-rectification efficiency with 50mV ripple for clean power
  • Sealed aluminium housing operates reliably from -40°C to 80°C

Target application

This compact buck converter steps down 18 to 60 volt DC sources to a regulated 12 volt output at 30 amps. It suits golf carts, industrial vehicles and off-grid systems that need reliable 12 volt power from higher-voltage batteries.

Thermal and electrical behaviour

Synchronous rectification delivers up to 95 percent efficiency with only 50 millivolt ripple, keeping heat low during continuous 360 watt loads. The aluminium shell is epoxy-potted for waterproof, dust-proof and shock-proof operation across a minus 40 to plus 80 degree Celsius range.

Integration requirements

Two connectors are included for straightforward wiring to the source and load. Built-in over-voltage, over-current, short-circuit, reverse-polarity and over-temperature protections guard the converter and downstream gear without external components. Buyers needing isolated outputs or higher current must look elsewhere.

Questions about this item

How do I wire the BZONE-PC12-30A into a 48 V golf-cart system without triggering the 2-second start delay?

Connect the input leads to the 36–48 V battery pack observing polarity, then attach the 12 V 30 A output to your accessories; the converter begins delivering power automatically after the built-in 2-second delay once input voltage is present.

What component should I check first if the converter stops working after years of daily use?

The internal fuse supplied with the unit is the primary replaceable part; inspect and replace it if the converter shows no output while the 18–60 V input remains within range.

At what temperature does the over-heat protection activate and shut the unit down?

The converter is rated for continuous operation up to 80 °C; the over-temperature protection engages when the internal temperature exceeds this limit, cutting output until the aluminium housing cools.
