Small rectangular waterproof step-up converter with short cable leads

GCON

GCON DC 12V-24V Step-Up Converter 5A 120W Waterproof

SKU CH-841D-0EVCZ

A waterproof step-up converter raises 9-20 V input to 24 V at up to 120 W with built-in protection

  • Steps 12 V input up to 24 V output for 24 V equipment
  • Accepts 9 V to 20 V input range for flexible vehicle power
  • Delivers up to 120 W with built-in overload and over-heat protection
  • Waterproof housing suits vehicle, marine and outdoor installations
  • Compact 12 cm lead allows easy fit in tight spaces

Vehicle Power Conversion

This step-up converter raises a 12 V vehicle supply to a regulated 24 V output at up to 5 A and 120 W. It accepts a wide 9 to 20 V input range, making it suitable for cars, trucks, boats and solar installations that need stable higher-voltage power.

Protected Operation

Built-in safeguards defend against over-voltage, under-voltage, overload, over-heat and short-circuit conditions. The sealed waterproof housing keeps the electronics reliable in damp or exposed environments without adding audible noise or requiring active cooling.

Compact Wiring

A 12 cm lead set keeps the unit tidy and simplifies routing in tight panels or engine bays. The small footprint allows discreet mounting near the load, though installers needing longer cable runs or higher current capacity will need a different solution.

Questions about this item

How do I wire the 12 cm input and output leads without reversing polarity?

Connect the source to the labelled 9-20 V input leads, then attach the load to the 24 V output leads; the short 12 cm cables leave little slack, so verify polarity with a multimeter before sealing the waterproof housing.

Which protection circuit is most likely to trip first during continuous 5 A operation?

The over-heat protection will activate before the 120 W limit if the sealed case cannot dissipate heat, shutting the converter down until it cools.

What input-voltage drop causes the converter to shut down under load?

The under-voltage protection cuts output when the supply falls below 9 V, so a sagging 12 V battery or long supply cables can trigger it before the 5 A rating is reached.
