KEHIPI

KEHIPI HL-DC840-138 8V-40V to 13.8V 10A 138W power adapter

SKU CH-PXEK-N5HNE

Converts 8 V–40 V input to a stable 13.8 V 10 A output with 95 % efficiency in an IP68-rated aluminium housing

  • Type8V-40V to 13.8V 10A
  • Dimensions32.0 in x 75.0 in x 32.0 in
  • Weight248 grams
  • Wide 8V to 40V input powers 12V 24V 36V systems
  • 95 percent efficiency from synchronous rectification cuts energy loss
  • Smart chip guards against over current overload short circuit overheat
  • IP68 aluminium epoxy housing survives dust water shock vibration
  • Operates reliably from minus 40 to 80 Celsius

Input Range and Output

The KEHIPI HL-DC840-138 accepts a wide 8 V to 40 V input and delivers a regulated 13.8 V at up to 10 A. It serves golf carts, club cars and similar 12 V, 24 V or 36 V nominal systems that need a stable 13.8 V supply. The non-isolated module steps voltage up or down automatically within the stated range.

Build Integration

The converter measures 32.0 in by 75.0 in by 32.0 in and weighs 248 grams, fitting into tight compartments without adding bulk. Its epoxy-potted aluminium shell provides IP68 waterproof, dust-proof and shock-resistant protection. A two-second start delay prevents inrush issues when the vehicle powers on.

Thermals and Efficiency

Synchronous rectification using MOSFETs pushes peak efficiency to 95 percent while keeping ripple at 50 mV. The potted aluminium housing doubles as a heatsink, allowing reliable operation from minus 40 °C to plus 80 °C. Built-in over-current, overload, low-load, short-circuit and over-temperature protection shuts the unit down safely under fault conditions.

Questions about this item

At what input voltage does the converter reach its 10 A output limit?

The converter delivers up to 10 A output across the full 8 V to 40 V input range, so the current limit is reached at any input within that window.

How much heat does the aluminium shell dissipate during continuous 138 W operation?

With up to 95 % efficiency, only about 7 W becomes heat; the epoxy-potted aluminium case spreads that heat passively from -40 °C to 80 °C ambient.

What wiring or connectors must I supply to install this module?

The unit arrives as a bare potted block with no cables or plugs; you must provide your own input and output wiring suited to 10 A at up to 40 V.
