Description

THIS is a remarkable, new cost and time-saving device is called the DC-Hub. Imagine a simple, extremely robust DC input/output fuse box combination board that reduces workshop time by a large factor, but also does away with the need for specialist expertise when building DC electric setups.

All components are wired to this single central hub, including AC chargers, solar panels, and DC chargers. From the same unit, wires run to all accessories, such as fridges, lights, compressors, and more. This can all be done without the need for crimps, lugs, shrinks, or expertise. All the time-consuming work is done for you!

It connects all elements of a DC installation, including first battery, auxiliary batteries, DC-DC, alternator, solar, DC-DC, and other charging devices.

The highest quality connectors mean that soldered or crimped lugs, as well as heat-shrink, are unnecessary.

This reduces labour time and the need for expertise and speeds up fault finding and warranty comebacks.

Tested to Destruction

We proved that our goal to over-engineer the DC-Hub worked, putting massive current over-loads through the connections and PC board, over extended time periods, resulted in no warping, melting or any significant damage of any kind. We abused it beyond anything that could happen in the real world, and it came back smiling. And amazingly, even though we tested one to destruction - it still works faultlessly. We could not destroy it!

Fuses

The DC-Hub is not supplied with any fuses.

Connector Explanation

The house (aux) battery (AGM, LiFePO4, flooded Lead Acid, etc…) connects to connector P3 and needs an external 150A fuse at the house battery bank. Any size battery bank can be used. The DC-Hub is not limited to a certain Amp Hour size.

The start battery gets connected to connector P8 and needs an external fuse at the start battery of your vehicle. Solar panels can be connected to connector P7. Both connectors P8 & P7 positive cables are linked to connector P6 to simplify the connection to a DC/DC charger with integrated MPPT controller. All ground connections of every single connector are linked on the circuit board. A DC/DC charger with integrated MPPT controller (Redarc BCDC range, Enerdrive DC/DC, etc…) can be connected to connector P5 with charge output and ground and to connector P6 for solar and start battery input. All loads (like compressors, fridges, lights, charge ports, etc…) can now be connected to the remaining connectors and will be automatically connected to the house battery.

Connectors P4 & P5 can handle a constant 80A load. To prevent the Maxi Fuses from overheating please use two Maxi Fuses.

Example: When connecting a DC/DC charger to connector P5 that requires a 60A fuse insert 2 x 30A fuses into fuse holder F13 & F13A. Do the same with connections to connector P4 and use the fuse holder F14 & F14A.Connectors P9 & P10 can only handle 40A constant load or 80A intermittent load. Currents of 40A must not be exceeded for more than 10 minutes at a duty cycle of 50% (10 minutes on / 10 minutes off) to allow the contacts to cool.

ATTENTION:

• Fuses are meant to fit tightly in the sockets on the DC-Hub Board.

• Do not attempt to pry open the receiving sockets to make fuses easier to remove.

• The tight nature of the fuse in their holders ensures minimal voltage-drop.

• If they become loose-fitting, the connection may heat up, and voltage drop and efficiency will be reduced and damage can occur due to heat build up on the fuse holder.

• If you find a fuse that is not tight in its holder, we recommend using pliers, gently squeezing the connector before inserting the fuse.

• Pay special attention to the DCDC charger connection fuse (P5).

Tightening Torque Settings & Connector Maintenance

It is extremely important to tighten the screw terminals on the DC-Hub connectors properly. Please use the following torque settings to tighten the connectors:

• 150A connector: 3.5Nm

• 80A / 40A connectors: 1.5Nm

• 25A connectors: 0.6Nm

Ensure all unused clamps are tightened to prevent rattling from the circuit board. In high-vibration applications, make sure you check the screw tensions as part of your regular vehicle maintenance schedule.

Cable Ratings and Fuses

The following chart can be used as a guideline for picking the right cable size for your application. We also integrated a guide for picking the right lug and heat shrink size. Never exceed the amp rating for a cable. Always use a fuse that is smaller or equal to the maximum current carrying capability of the cable that you are using. Never exceed the manufacturer's recommended fuse rating for the appliance you are connecting.
