Safely replace multiple AC-DC power bricks for VorTech, Gyre, ReefWave, Protein Skimmers and other DC pumps and loads in your aquarium with the DCBuddy. DCBuddy is compatible with 12V, 24V, 32V and 36V equipment.

DCBuddy works with Home Assistant directly as its powered by ESPHome firmware, which can be quickly customized by the end user and re-flashed. ESPHome firmware is mostly written in a delcarative style (no volumes of C, C++ or Python) meaning its easy to re-map or adjust features.

Each DCBuddy can replace up to 7 AC-DC power adapters or bricks at one voltage (either 12V, 24, 32V or 36V) using one large, industrial power supply (power supply not included).

For example, the following equipment is well suited with DCBuddy:

  • DC pumps, such as Gyres, Vortechs, etc
  • ATO pumps
  • Aquarium controllers
  • Small refuge lighting or other accessory lighting
  • Fans

The voltage chosen depends on the equipment you are powering:

  • Many DC pumps are 24V (Gyres, MP10wQDs, many skimmer DC pumps).
  • Some DC pumps are 32V (VorTech MP40wQD) and will also operate at 24V, but may not reach 100% peak flow.
  • Larger DC pumps are 36V (Vectra, main return pumps)

Features and Specifications

  • Maximum total current of 10A input (approximately 240W @ 24V, 120W @ 12V).

  • Per port 3A max sustained, 5A peak current (approximately 72W @ 24V).

  • All ports are short circuit, over-current and over-load protected @ 5A.

  • Uses standard 2.1mm x 5.5mm barrel jacks as output ports. Cables not included (sold here, and commonly available from other sources). Some equipment requires 2.5mmx5.5mm barrel jacks, of which the “forked” kind of 2.5mm cables are compatible.

  • WiFi connected to Home Assistant or local web server, including per-port on/off control and current monitoring. No clouds.

  • Integrated status display (OLED)

  • Open Source Hardware and Firmware: firmware update over OTA or USB-C.

  • Works with upcoming DCBuddy Battery and DCBuddy Multiple-Voltage Redundant Input Hub!

Multiple power input options.

Power Inputs:

  • 2.1mm x 5.5mm barrel DC Input (5A max!)
  • DIN-4 Power Input (for Meanwell OWA power supplies)
  • Molex Micro-Fit 3.0 8-pin DC+CANbus input (for Battery, 32V, and Hub addons), also features a terminal block adapter accessory
