The EnergyBar 4 module features 4 independently controllable outlets. With power failure detection, active electrical current monitoring, and failsafe features make this power bar far better than any competing units.

  • Plug and Play
  • Built-in 4 Port hub so that accessories can be easily added
  • Active electrical current monitoring and logging
  • Fail-safe features. On communication failures outlets revert to user settable default settings
  • High reliability direct wired connection to the Apex System (does not use X10)
  • All four of the outlets use mechanical relays for switching
  • Up to 240 EB4s can be daisy chained together for up to 960 switched outlets
  • Built-in circuit breaker Protected
  • 4 Mounting Holes for easy installation
  • Compact custom aluminum enclosure (7.5" x 3.75" x 1.8")


APEX Ready
When you connect Apex Ready certified products to your Apex System, many new options will unfold. How about having your LED lights dim or change color temperature at the touch of your iPad? How about programming your Tunze or VorTech pumps for some serious wave action? That’s what you get when you pair up the Apex System and an Apex Ready certified product.

“Neptune = Perfect”
5.0

This EB4 is running the gear attached to my DT. I have a basement fish room with an EB8 for control down there. The EB4 is controlling off/on for my AI Hydras (Mostly emergency off if necessary) and on/off for my Gyre for feeding. I still have a ginormous 300W Eheim Jager in my overflow providing...Read More

“Reliable”
5.0

Best module for running low wattage dosing pumps. It turns the outlet on or off reliably as programmed unlike the triac switch outlets on the EB8 which needs a higher wattage device plugged in. The apex may say the EB8 triac switch outlet is off but the outlet is still providing power causing the d...Read More

“Excellent”
5.0

Easy to install. Easy to program. I bought this to replace three unreliable timers I was using with dosers. I have a lot more confidence knowing that the program can't be manipulated by a single push of a button. Another excellent product from Neptune.

“Energy Bar 4”
5.0

Excellent addition to your Neptue system. I have this in my pump room wich is 20 feet away from the display tank, probe module, and EB8. I also have the display unit in this room; it has a fixed cable so instead of using an extender I plugged it into the EB4 and used a 30 foot USB cable to connec...Read More
