GCON DC 17-55V to 12V 20A 240W Step-Down Converter

SKU CH-1GE4-AMMCQ

A step-down converter that accepts 17 to 55 V DC input and delivers 12 V at 20 A with IP67-rated protection

  • Steps down 17-55V to stable 12V 20A output
  • Intelligent protection guards against over-voltage, under-voltage, overload and short circuits
  • IP67 aluminium housing is waterproof, dustproof and shockproof
  • Operates reliably from -40°C to 80°C
  • Delivers 240W continuous power for heavy-duty vehicle and solar use

240W Step-Down Converter for DC 17-55V Systems

This GCON converter reduces a wide DC input range of 17 to 55 volts to a stable 12 volt output. It is built for vehicle, marine, solar and industrial equipment that needs reliable 12V power from higher-voltage sources. The unit delivers up to 20 amps continuous current.

IP67 Aluminium Housing with Full Protection Suite

The one-piece aluminium heat-sink case is epoxy-potted for 100 percent waterproof, dustproof and shockproof operation. An intelligent protection chip monitors for over-voltage, under-voltage, overload, low-load, short-circuit and over-temperature conditions. The converter operates reliably from minus 40 to plus 80 degrees Celsius.

20A Output Comfortable for Most 12V Loads

At 240 watts the converter comfortably runs lighting, communication gear, security cameras and similar 12 volt loads. It reaches its limit when multiple high-draw accessories are powered simultaneously. Buyers needing more than 20 amps or a different output voltage must select a higher-capacity model.

Questions about this item

Will the aluminium heat-sink housing or epoxy potting need any periodic maintenance?

The one-piece aluminium housing with epoxy potting is sealed to IP67, so no user maintenance is required for the enclosure or thermal path.

What limits continuous 20 A output before the protection circuits intervene?

The over-temperature protection activates if the housing exceeds 80 °C, which is the first limit reached under sustained full-load operation.

How much heat and noise does the sealed unit produce when running at 240 W all day?

The fan-less, potted design runs silently; all 240 W of loss dissipates through the aluminium housing, which will become hot but stays within the rated -40 °C to 80 °C range.
