KEHIPI DROK 4A 35W & 4A 60W DC Buck Boost Converter Bundle

SKU CH-0KE4-HYQB6

Bundle includes two DC buck-boost converters delivering adjustable 0.5-30 V output at up to 4 A, rated 35 W and 60 W respectively

  • Colormulticolor
  • Adjustable 0.5-30V output suits diverse DC projects
  • 4A 35W module handles 5.5-30V input for flexible power sources
  • 4A 60W module accepts 6-30V input for higher power needs
  • Over-current protection safeguards connected loads during operation
  • Case requires manual assembly after transit-safe disassembly

Versatile DC Buck Boost Converter Bundle

This bundle includes two adjustable DC buck boost converter modules rated at 35W and 60W. Both units deliver a maximum output current of 4A across a wide output voltage range of 0.5V to 30V. They suit hobbyists, engineers, and technicians who need flexible voltage regulation for prototyping, battery charging, or driving high-power LEDs in a compact form factor.

Integration Requirements and Build Flexibility

The 35W module accepts an input range of 5.5V to 30V, while the 60W module operates from 6V to 30V, allowing both to be powered from common bench supplies, battery packs, or solar sources. Each module features over-current protection and adjustable constant-current operation, so they can be wired directly into custom enclosures or test fixtures without extra protection circuitry. The cases arrive disassembled for safe transit and require manual assembly before use.

Power Headroom and Practical Limits

The 35W unit provides up to 35W continuous output, while the 60W module is rated for 60W maximum with a recommended operating ceiling of 50W and 3A for sustained reliability. Both converters maintain regulation across the full 0.5V to 30V output span, making them suitable for lithium-ion chargers, LED strings, and variable lab supplies. They are not designed for applications demanding higher wattage, isolated outputs, or automated case assembly.

Questions about this item

How long can the 60 W converter sustain full load before thermal limits cut in?

The 60 W module is rated for 50 W continuous use; running at the 60 W maximum will trigger thermal protection sooner.

What noise or heat should I expect when the 35 W unit runs all day at 4 A?

Both converters are passively cooled with no fan; expect silent operation and noticeable warmth at sustained loads.

What power source must I already have to use the 35 W converter at its 30 V output?

You need a DC supply that can deliver at least 5.5 V and enough current for the desired output power.
