Specifications

Back to Power-5HV index

Lots of projects need power, especially LEDs! In 2024 there are more options then ever and some of those now use 36v (Govee for instance) or even 48v (puck style RGBW lights)! To adopt to this you can use the Power-5HV in your Dig-Octa stack (compatible with all other Dig-Octa hardware) to be able to control these natively.

The power-5 was already available as a “normal” version and now also in a HV version which denotes the “High Voltage” version meant specifically for between 24v to 48v. The Power-5 has no HC (High Current) version.

Design Goal

The power-5 is built around 12x 5.08mm pluggable output terminals divided over 2 sides. The power-5 in the series of powerboards has been specifically designed to allow for a stackable form factor which means that all output ports (but not the fuses) can still be reached even when multiple powerboards are stacked on top of each other.

The HV version of the Power-5 has changed to different fuses both for the input fuses and output fuses.

All output terminals are equipped with individual fuse sockets allowing you to select the individual value fuse value per output terminal. This can optimize the fuse for the expected draw and the wire diameter used to create a safe setup.

The HC version of the power-5 has 3x 9.5mm barrier terminal blocks for input of power allowing for connecting up to 3x parallel wires from a single power supply to minimize voltage drop between the power supply and the powerboard. Each individual terminal supports up to 10A to enter the board so to use the maximum potential of 30A continuous you will need to have all 3 terminals wired up!

Advised Power Supply

This board is ideally suited to be used with a Meanwell LRS-600-48 (12,50Amps @ 48v) or bigger. As suggested above the maximum current for the power supply is around 30Amps total. Sadly such big power supplies (1440w) are quite expensive! There is no issue using a lower current power supply.

*Connecting multiple power supplies to a single powerboard is not allowed, if you wish to use multiple power supplies (even with different voltages) this is allowed within a stack so will require multiple boards.

Specifications

  • 3x 9.5mm “barrier block” input terminals for both positive and negative
    • Allows power input wires using
      • Bare wire
        • Also when soldered (not recommended)
      • Wires with crimped on wire ferrules
      • Wires with crimped on fork style crimps (preferred)
    • With the right style fork crimps allows for up 3x 10AWG input wires with fork crimps
    • Maximum current per input terminal is 10Amps (because of auto-reset fuses on input)
      • Combining 3 gets you the 30A max continuous total
  • Board recommended max 30Amp continuous load total
    • Fore more detailed power handling rules please see the dedicated article
  • 12x 5.08mm pluggable output terminals
    • Allows up to 14AWG/2.0mm2 cable with ferrule
    • Has both + and – on single connector
    • Fuse socket per output
    • Max 10Amps fuse recommended
      • ! 10Amps @ 48v is a **A LOT** of power, please fuse according to what you require and the wires connected. This is why by default only 5A fuses are included.
  • 24v-48v capable
  • “Broken Fuse” light per output
    • Custom independent “constant brightness” circuit
  • Onboard capacitors
    • Features 2x 680F 80v big capacitors
      • Smooths high transient loads and voltage spikes
    • Per output 1uF 100v capacitor
      • Provides noise filtering on output ports
  • Onboard Voltage display
    • Shows actual voltage including potential voltage drop from PSU to board
    • Easy to identify voltage of powerboard in a mixed voltage stack!
  • 4x M3 mounting holes
    • Connected to GND
