This is the official 120-240 volt - 12 Amp 8 Outlet AC Power Bar for the Robo-Tank DIY Aquarium Controller, it has no CE approval yet however all parts used are CE approved, overrated and of high quality. The power bar contains no high voltage wires internally and a heavy duty circuit board ensuring maximum safety.

Built to Last

Because these are constructed using high quality components and parts you'll have ample time to build a long term relationship with your power bar. To start it features a heavy duty printed circuit board using 2 ounces of copper instead of the typical single ounce, this will keep the current flowing without lifting the foil. 

Each of the 8 outlets are independently switched on and off using solid state relays (SSR's) which are the Cadillac of relays. These are electronic and contain no moving parts which dramatically increases their life span, they can be switched millions of times and no need to worry about contacts corroding from saltwater environments.  SSR's are also silent and switch instantly unlike their electromagnetic counterpart. 

Inductive loads, bring 'em on. Motors, fans, pumps and the like are no problem, each SSR is fully isolated up to 1500v and have a snubber and TVS circuit keeping them safe from over-voltage caused when inductive loads are switched off. Each outlet also has it's own fuse with a larger fuse for the overall power bar that will keep everything safe.

Fail Safe Detection

This isn't your average power bar, we know in the real world a lot can happen but with the Robo-Tank AC power bar you're covered. First if the power bar loses communication with the controller it will go in a fail safe mode. This is also great for power outages, if you have the power bar connected to an uninterrupted power supply (UPS) your protected from disaster. Each outlet will automatically go into a default state and keep your tank on life support. Once the power is restored and connection is resumed to the controller everything will resume back to normal operation. This is achieved using on board jumpers on located on the circuit board.

Spare USB Expansion Port

Enjoy a spare USB port to add another AC power bar to your setup or any other Robo-Tank accessory, no need for expansion hubs. Robo-Tank can support up to 8 power bars but it's possible to connect up to 127 power bars to your project.

Power Ratings

The power bar can be used worldwide, it operates on 120v-240v AC and can withstand 15 amps of current overall but fused at 12 amps for extra security (universal version is fused at 10 amps). Each of the 8 outlets are individually fuses at 7 amps so in the event of a catastrophic equipment failure the fuse will blow and protect  the power bar and any other equipment connected.

LED Outlet Indicators

Never be left guessing, each outlet has an LED indicator so you always know if an outlet is on or off, this is handy feature that is often overlooked. There's one additional LED which is lite when when the power bar is fully energized so you know all systems are working.

Fully Serviceable

Something nobody likes to think about but life happens and sometimes things break, that's why the power bar was designed to be fully serviceable. If you can use a screwdriver and soldering iron anything can be replaced on the PCB, no need for expensive replacements.


The power bar not only works with Robo-Tank but it's compatible with any microcontroller that has an I2C bus such as any Arduino or Pi. There will be an open source Arduino library available so you can be up and running in no time with your own project.

1 Year Warranty

Like the other industry leading competitors you can be at ease with your Robo-Tank power bar as its comes with a 1 year warranty, if you anything fails simply contact and ship the power bar to us and it'll be repaired or replaced in a timely fashion. Please note the warranty doesn't cover abuse or water damage and is not transferable. 

Package Includes

  • Robo-Tank 8 Outlet AC Power Bar (242.8mm x 147mm x 40.5mm)
  • 5' AC Power Cord
  • 6' USB A Male to Male Cable
  • Case is 3D Printed, they are strong but there maybe some imperfections

Please note the power bar is still being developed and expected to ship May 8th - May 14th. Ordering today will help in the development and allow you to save $60. If you don't plan to use this with Robo-Tank you should add the optional I2C buffer which will extend the cable length up to 15m. A typical I2C bus doesn't put out much power, a buffer will strengthen the signal allowing more cable or devices to be connected. The drawings are what to expect but there may be small changes. 

If you select universal outlets there will be an extra month delay.
