KEHIPI DC 8-35V to 9V Buck Converter

This buck converter steps a wide DC input range of 8 to 35 volts down to a stable 9 volt output at 2 amps, delivering up to 18 watts. It suits automotive and solar installations where 12 volt, 24 volt or 30 volt sources must power 9 volt equipment such as navigation units, audio gear or LED displays.

Natural cooling with aluminium case

The module relies on natural convection through its aluminium housing, which measures 35 by 26 by 21 millimetres. Conversion efficiency reaches over 95 percent maximum, so heat generation stays low during normal operation. Built-in safeguards include over-current, over-temperature, reverse-polarity and short-circuit protection, plus waterproof, dust-proof and shock-proof sealing.

Pre-wired leads with mounting holes

The unit ships with 13 to 14 centimetre input and output cables already terminated: red and black for input, yellow and black for output. Two mounting holes spaced 41 millimetres apart with a 4 millimetre diameter allow secure panel or chassis fixation without additional hardware.

Questions about this item

How do I wire the 13-14cm input and output cables to a 12V or 24V source?

Connect the red wire to input positive and the black wire to input negative; the yellow wire is output positive and the other black wire is output negative.

What maintenance does the aluminium-cased 18W module need over time?

No scheduled maintenance; keep the case vents clear and check that the 4mm mounting screws stay tight so natural cooling works.

At what point does the over-temperature protection trip during continuous 2A load?

The internal protection activates when the case temperature approaches the 80°C upper operating limit.
