Normal vs HC version

Some of the powerboards will be offered in a normal version and a so called “HC” High Current version. These versions are exactly as the name suggests, they are high current variants of the normal boards raising the continuous current from 50Amps continuous to 100Amps!

That is a huge amount of current and generally will make most sense in 5v installs where even a single 300 LED strip can use up to 13Amps.

Different input stage

To allow for up to 100Amps to make it into the board the input stage of the HC boards is different. They are equipped with large M5 bare terminals to which you can screw very large wire sizes (6AWG/13.3mm2) with fork, ring or lug crimps.

For the positive side there is another set of these M5 bare terminals on the board, between those a “Midi”/ANS style fuse is connected, this is to protect the 2 input wires from potential issues.

Requires fork, ring or lugs

These M5 bare terminals cannot take bare wire or wire ferrules but require either fork style, ring style or lug style crimps on your cable to be able to connect them. You need specific tools to attach these to your cable so please be mindful of that before buying the HC version boards!

Extra copper

The HC boards are manufactured with extra thick copper planes vs the normal versions to better be able to carry the current and dissipate protentional heat.

Higher cost

Now you ask, why not only make HC versions, 100Amps capability sounds awesome! And yes, while it certainly is, I hope the above explains why there are also normal versions. The more complicated cabling required and the extra costs for those components on the board combined with thicker copper and more complicated manufacturing means these boards cost more then the normal versions.

Please take the above into account when deciding between a normal or HC version of the powerboards.
