This is a topic other controller companies like to avoid. Why? Because not all monitoring ports are created equal. Galvanic Isolation is key to getting accurate readings on pH, Temp, ORP, and Conductivity. Some controllers either do not do it well (they are still figuring it out) or possibly not at all.
So what is Galvanic isolation? Well, the tech-answer is that it’s where two or more electric circuits must communicate, but their grounds may be at different potentials. It is an effective method of breaking ground loops by preventing unwanted current from flowing between two units sharing a ground conductor.
Now of course that is all geek-speak to most of us so let’s just put it this way: on a controller without galvanic isolation, your readings of pH, Temperature, ReDox (ORP), Conductivity/Salinity, etc. will be completely inaccurate. Of course it costs us more to add this circuitry into the Apex, but what good is a controller if it doesn’t give you accurate readings?
The Apex Base Unit comes standard with four channels of 0-10V control. These outputs are controlled in the Apex software and are most commonly used for LED dimming or Tunze speed control pumps. By using one of our optionally available cables, you can connect any Apex Ready 0-10V device to these ports. This means you can do cool things like have your LED lights ramp up and down to simulate sunrise and sunset!
They can also be used for various DIY purposes like controlling the dimming level on Meanwell LED drivers. Should you need additional channels of 0-10V control, no problem, simply purchase our VDM module and get four more – and also get a connection for Apex Ready+ LEDs!
The Apex Base Unit comes with an external 12V power input. With an optionally available wall transformer and a second Energy Bar, this enables you to configure your Apex for power-outage mode. You just plug the 12V transformer into your Apex and then into a UPS (uninterruptible power supply) along with your extra Energy Bar. You then plug a powerhead and an air pump with stone into this Energy Bar. If the power should ever go down, your Apex will sense the problem, and will activate the powerhead and air stone potentially saving the day for your fish and corals!
So Much More Than Just a Power Strip!
The Energy Bars available for our Apex systems are much more than a glorified power strip. In fact, this component of your aquarium controller equipment is far more important than most people realize – and not all systems are created equal!
It is obvious that this component is key to controlling things on your aquarium, but what is not so apparent is how it is critical to preventing catastrophe in your aquarium. Here’s how.
Each of the independently controlled outlets on the Energy Bar are independently switched and easily carry the current load specified on the label. In fact, we intentional underrate our outlets just to provide that extra level of security. So, depending on which Energy Bar you purchase, each outlet is rated from 5A to 10A at 120V AC or 8A on our 240V European model.
Current Sensing Device
The Energy Bars continually send their information on their present current drain to the Apex controller. This is incredibly useful information for a number of reasons. First, it enables you to recognize what the overall power consumption is on any Energy Bar so that you can better distribute the load across your multiple Energy Bars. Also by having this feature you can accurately determine the power utilization of your tank to compare different lights, pumps, skimmers, etc.
Soft-Start Extends the Life of Pumps
Imagine revving the engine in your car and dropping the shifter from P to D. That is exactly what happens when many controllers turn on the power to your pumps. Just like in a car, this kind of instantaneous application of power to your return pump after a feed cycle or to your power heads will certainly lead to early failure. With the Energy Bar, power is slowly ramped on so that every motor is safely brought up to speed without the damaging torque.
Power Failure Detection, Communication Error Protection and Pre-programmed Failsafe State
Each Energy Bar outlet can be configured to be either in an off or on state if the power were to fail and then come back on or if there was a communication failure with the Apex base unit. This means that if, for instance, your heater was on when the power went off, you could have it programmed to be off until control was reestablished with the Apex base unit. Or, as another example, you could program your main return pump to always be in the on position in case of failure.
This feature is very important as many other controllers on the market may leave the outlet in its last position or possibly default all of the outlets to off or on. This is even true if they simply lose communication with their base unit due to a system failure, software bug, communication issue, lightning strike, etc. Not good. Imagine if you were away from home and a storm took out your Apex – the Energy Bar would just fall back to the Failsafe state you had programmed for such an incident. No worries.
One additional advanced feature is that when you use an additional Energy Bar on a UPS (uninterruptible power supply) you can have key lifesaving devices (low power power heads and bubblers) on there that will automatically go into their Failsafe State once power failure is detected. This can keep your tank alive and healthy for hours on a good UPS until the power comes back online. This will run completely unattended and is ideal to give you peace of mind when you are away from home whether out for the evening or on a two-week cruise!
It is easy to see the importance of this one small feature that differentiates the Neptune Systems Energy Bars from the rest and how once again Neptune Systems is looking out for every possible way for you to avoid catastrophe in your aquarium.
Extra AquaBus Connections
Each Energy Bar has additional connectors so that you can easily expand to other modules. This is very helpful for those that want to use one Apex to control multiple aquariums. The Energy Bar becomes an AquaBus “hub” at any location you choose – allowing you to connect more modules in that area. This is called a “star topology” and is unique to the Apex. Many other controllers require you to daisy chain together every module or they require you to buy a separate “hub” to connect everything together.
The Apex Display module is a sleek and compact way for your to interact with the Apex Base Unit and control nearly every aspect of your Aquarium.
Mechanical, not membrane keypad
Our Display Module uses high-quality, mechanical buttons. So what you say? Well many devices out there make use of what are called capacitive touch pads. This type of membrane button is just fine for your toaster oven, but in a saltwater environment it is highly susceptible to failure. So, even though the cost to us was higher, we went with mechanical buttons for our Display Module ensuring your product a much longer life.
Adjustable contrast, high-resolution,backlit graphic display
While some may tout the importance of a color display, we disagree. We believe the most important thing for our customers is ease in readability and size of the display. What good is a color display if it is barely larger than a postage stamp. That is why we went with the backlit graphical display we did. It was the perfect match of function and value for our customers.
Built-In Speaker Plays Multiple Alarm Tones
Inside the Apex Display Module is a tiny speaker with a big heart. This speaker will play one of many alarm sounds and tunes that are built into the Apex. These alarms are perfect to alert you of a water leak, over temp, or whatever you condition you desire to program into the Apex.
Multiple Display Module Capability
With the Apex Display Module you are not limited to having just one control panel. With the Apex (as an option) you can add one, two, even three control panels all to the same Apex. And, these are not watered down, smaller versions of the main control panel, all modules will have the same display and functionality.
