- ReefKeeper PB4 Power Bar Module - Digital Aquatics (DISCONTINUED)
Having a controllable power bar connected to an aquarium controller can make your life easier than you ever imagined. If you have ever done a water change and forgotten to turn equipment back on after that will be a thing of the past. With ReefKeeper aquarium controllers you can make the outlets on a PB4 do almost anything you dream of. From turning equipment off or on for water changes, feeding, maintenance, dosing, temp control, or what ever you can think of.
Digital Aquatics has completely redesigned their PB4 power bars. The PB4 power bars connect with all ReefKeeper lite and elite controllers through the BUS connections for an additional 4 outlets of control.
- LED status indicator for each outlet
- 2x Relay Channels per power bar (outlets 1 & 4)
- 6' power cord
- Includes 6' BUS cable
- Includes mounting screws
- Snubber Circuitry on outlets 2 & 3 allowing low wattage items to be controlled
The new PB4 for the ReefKeeper controllers has been reworked to allow the non-relay channels the ability to control low-wattage items. In the past with the older solid-state channels controlling low power consuming products can be un-reliable. Digital Aquatics has implemented a snubber circuit into channels 2 and 3 to make them reliable.
Channels 1 and 4 are relay controlled and can control up to 8 amps per outlet, where channels 2 & 3 are controller by a solid state snubber circuit allowing up to 3 amps per outlet. With any electrical item safety is number one, and Digital Aquatics includes a 15 amp circuit breaker that can be reset to prevent any trouble.
Dimensions: 10.8″ x 2.2″ x 1.9″
- LED status indicators
- Strong convenient mounting tabs
- Relay channels rated to 8A max each
- Solid state channels rated to 3A each
- Power rating: 1800W (15A)
- Soft start/zero crossing

Note: Compatible with all ReefKeeper Elite and Lite models. Not compatible with ReefKeeper 2.
Necessary Interface By Ken on 6/22/2016Ken would recommend this product to a friendA bit pricy for only four outlets but otherwise works well.
Works as described By Jeremy on 5/23/2016Jeremy would recommend this product to a friendEasy to hook up and program. I wish they had a bigger power bar though. $100 a pop adds up
Not so sure about this one.... By CKF on 2/3/2016CKF would recommend this product to a friendI just got a reply back from Digital Aquatics support that said "All pb4's have the snubber circuitry in them." This product's description is implying that this is a recent development. Apparently it is not.

I’m considering using BRS risers but can’t figure out which of the outlets on this are TRIAC and which are mechanical relay outlets. Can you help please?
For the DA PB4 unit, outlets 1 and 4 are relay controlled and 2 and 3 are controlled by a solid state snubber circuit.
Have a great day.
Does adding a 2nd PB4 to a SL2 count as an additional module or still as only one of four?
The PB4 second will count as an additional module. Feel free to let us know if you have any further questions.
Does the lite controller support 3 powerbars? Or is two the max it can take on?
The ReefKeeper Lite can handle up to 4 modules of any type. If 3 of those modules are PB4 Powerbars and one module is the SL1 then that is totally fine and will work. The only limit is 4 modules total, the iTemp probe, and head unit do not count against the module limit but any others like PB4’s, SL1, SLX, MLC, etc are all modules that will count against the limit.
Can this be used independently or does it need to be pugged into a controller?
The ReefKeeper Powerbars will need to be attached to either a ReefKeeper Lite, or ReefKeeper Elite to function properly.
