GCON

GCON DC/DC Step-Down Converter 12V/24V/36V to 9V 4A Waterproof

SKU CH-JBVR-CCQ4K

Converts 12V, 24V or 36V inputs to a stable 9V 4A output in a waterproof, epoxy-sealed housing with overload protection

  • Wide 12V-36V input suits many vehicles
  • >96% efficiency keeps heat below 40°C
  • Built-in overload and voltage protection ensures stable output
  • Waterproof epoxy housing survives harsh environments
  • Compact auto-recovery design simplifies installation

Power input range

This GCON step-down converter accepts 12 V, 24 V or 36 V DC sources and regulates them to a steady 9 V output at up to 4 A. It is aimed at installers who need to run 9 V car accessories such as LED displays, media players or GPS units from higher-voltage vehicle systems.

Build and protection

The module is fully epoxy-sealed inside a waterproof housing for non-isolated operation. High efficiency above 96 % keeps heat dissipation low, while built-in overload, over-current, over-voltage and low-voltage protection with auto-recovery maintains stable performance in vibration-prone automotive environments.

Compatibility check

Verify that your source voltage falls within the 12 V to 36 V range and that the load does not exceed 4 A at 9 V. Confirm the device you are powering requires a non-isolated converter and that the physical dimensions suit the available mounting space in your vehicle.

Questions about this item

What input-voltage range does the 9 V 4 A step-down converter accept?

It accepts 12 V, 24 V or 36 V DC input and regulates the output to 9 V at up to 4 A.

What mounting provision does the epoxy-sealed waterproof housing have?

The fully potted module has no mounting holes or brackets; it is designed to be secured with cable ties or adhesive inside the equipment bay.

How do you wire the converter and which mistake causes no output?

Connect the supply to the marked input leads observing polarity, then attach the load to the output leads; reversing the input polarity triggers the protection and stops the unit until the fault is cleared.
