It’s More Cost-Effective to Implement (N120,000-N200,000) depending on the weight of the gate

This is true for a number of reasons. Firstly, DC devices have only two conductors (namely positive and negative) versus the three (live, neutral and earth) needed for AC equipment. Since DC allows us to operate at much lower voltages, less insulation is typically needed which in turn leads to reduced costs.

Also worth noting is that DC circuits are generally less complex and require less components and yet they provide superior motor control to AC (another benefit – especially from an access automation point of view where one can accurately adjust running speeds for enhanced safety and security requirements).

It can be powered by solar without the need of mains supply
flexible payment plans.

DC powered Motor

Why We Do Things the DC Way

A long, long time ago there was a very heated, very public battle of wits between DC disciple Thomas Edison and his AC adversary, Nikola Tesla. Their feud was what started the age-old power struggle (literally) between direct current and alternating current, and while there has since been numerous accusations that the Father of DC’s character was less than savoury, there can be no doubt that this method of power distribution has made the world a better place(as has AC!).

In fact, DC has made such an incredible impact on the world that it has become a fundamental part of our design philosophy. But why exactly has direct current become the preferred method of power distribution? Why is it that so many appliances nowadays has a built-in transformer and rectifier circuit to change the input AC voltage to low-voltage DC? And why do we at Nevosys bank on it with our own products?

Well, we’ll tell you…

It’s More Cost-Effective to Implement

This is true for a number of reasons. Firstly, DC devices have only two conductors (namely positive and negative) versus the three (live, neutral and earth) needed for AC equipment. Since DC allows us to operate at much lower voltages, less insulation is typically needed which in turn leads to reduced costs.

Also worth noting is that DC circuits are generally less complex and require less components and yet they provide superior motor control to AC (another benefit – especially from an access automation point of view where one can accurately adjust running speeds for enhanced safety and security  requirements).

Reliability and Autonomy

This point is probably a bit hackneyed, but we all know that it’s true. When the Dark Knight does rise (we’re talking about power failures, in case that metaphor was a bit obscure), it’s important that your appliances carry on working despite the sudden loss of mains power.

Direct current makes this a possibility. You’ve all heard the term “battery backup” being used – now, the battery being a staple of DC power distribution – is what allows your gate motor to dutifully carry on serving you even during lengthy power failures.  AC machines can still be outfitted with backup, but it requires costly additions such as DC converters. Backup is native to DC machines.

Lightning Protection

This point ties in very closely with the one above. Since DC operators gives you a mechanism to fairly easily decouple yourself from the main utility grid using solar power and other energy generators, you are effectively putting another level of protection between you and possible lightning damage.

Higher Starting Torque

While it’s true that AC motors produce higher running torque, think in terms of gate automation. What is more important: setting your gate in motion or keeping it that way? If you guessed “setting your gate in motion”, congratulations! You know your stuff. 
DC motors produce superior starting thrust, which is what you need especially if your gate is slightly on the heavy side. Once it’s on the move keeping it that way is, well, automatic.

Improved Collision Detection

DC machines have been found to be more sensitive than their AC counterparts from a collision detection perspective. This is an important feature to have in your automated system, especially if you have kiddies or pets around.

In a nutshell, the load speed profile of DC motors is such that they tend to slow down when obstructed whereas AC motors are synchronous and only slow down when they literally stall against the load. It is quite simply easier to electronically detect a DC motor hitting an obstruction which in turn allows us to apply more sensitive anti-crushing protection.
 
It Allows Us to Operate in the Safe Zone

Edison once notoriously performed a public demonstration involving an elephant to show the dangers of alternating current, but that’s kind of a cheap shot (not to mention utterly inhumane) and we won’t resort to that here. Besides, at high voltages DC can be much more dangerous than AC.

The fact is, the DC we employ in our gate motors is of the low-voltage variety (typically around 12-24V) which means that it is much, much safer than the AC alternative.

Please note that our aim is not to slate AC in any way. On the contrary, one of our most robust operators – the A10 – is an AC mean machine and offers myriad benefits such as a higher duty cycle and improved running torque that a DC unit might not be able to provide. Our goal is simply to provide you with some insight as to why DC is such an important part of our design philosophy.

Choosing the Right Gate Motor

Choosing the Right Gate Motor

Let’s say, hypothetically, that you have finally grown tired of your old jalopy and you’re in the market for a new, more reliable, mode of transportation. Naturally, there are a number of factors you would consider and things you would weigh up before finally settling on a car.

Is safety an important consideration for you? Are you in the market for a family sedan or a sports hatch? Are you looking for something with superior fuel economy?

Similarly, when you’re preparing to have your world rocked by the amazing security and convenience provided by a gate motor, there are some things you need to think about to ensure that you get one that’s right for your application. But don’t worry, with some handy tips from your favourite access automation company you’ll be wielding that remote like a magical sceptre in no time.

AC or DC  

We’re not referring to the Australian rock band of course (although our gate motors have been known to rock!), but rather to the form in which electric power is supplied to your operator.  AC, or alternating current, means that the gate motor is being powered directly via the 230V mains supply from a distribution board in your house.

DC, or direct current, on the other hand, is a method of power delivery relying on some sort of “power store” such as a battery. You’ll find that the vast majority of our gate motors are DC-operated.

And there’s a good reason for that. Power delivery, especially in Nigeria, is unfortunately quite unreliable, erratic and we’ve all borne the brunt of load shedding before. Your gate motor, being the holder of so many titles – security guard, butler, etc. – needs to be on duty around the clock, and DC units are able to continue operation even during lengthy power failures, whereas AC gate motors are not.

On the flipside of the coin, AC motors have a virtually unlimited duty cycle and will work tirelessly as long as they are being fed mains. Both of these modes of power delivery have their virtues, you simply need to decide which is best suited for your application. If you live in an area where power outages are commonplace, a DC unit is probably the best bet.

Weight of the Gate

Unless you’re an ant or former Governor of California (and sometimes actor) Arnold Schwarzenegger, you probably can’t carry much more than your body weight. But through the miracle of engineering gate motors are able to relatively effortlessly lug around several hundred times its own weight.

But that doesn’t mean it should be unrealistically loaded. Subjecting it to that kind of abuse will invariably lead to problems down the line, so first get an approximation of what your gate weighs before selecting a motor. The good news is that gates are usually much, much lighter than we think. For example, if you can lift one side of your gate to about the height of your shin, chances are it doesn’t weigh much more than 250kg.

Pull Force

This is more an extension of the previous point than a whole new heading. Pull force plays a monumental role in what gate motor you install, and has a direct impact on both the reliability and the service life of the operator. If you struggle to open and close your gate manually, be sure to choose a device rated for a high push force such as a D10.

The easiest and most accurate way to determine the weight of the gate is to use a pull scale as found in any angling goods store.

Swing or Slide

This one might seem fairly obvious if you already have a gate fitted, but if you’re looking to install a gate where there isn’t currently one this might warrant some thought. The truth is that both swing and sliding gate motors are equally rich in merit and which one you choose to fit simply depends on preference or, in the case of an existing gate, what the setup necessitates.

If you are going with a swing gate, remember to take into account factors like the length of the individual leafs, wind loading, etc.

If you follow these few simple selection guidelines you’re assured of a gate motor that’ll faithfully serve you for years to come. And if you do get stuck, remember that our technical support centre is open Monday to Friday from 7am until 6pm. Their number is 07033992255

Why Automate Your Gates?
Beyond the simplicity and convenience of opening and closing your gates with a remote control without having to leave your vehicle (which is most useful at night or in bad weather) electric gates have additional advantages over that of manual gates.
An electric gate eliminates the struggle with large and heavy manual gates that many people encounter. A simple press of a button on a remote control allows access. Visitors will usually use an intercom at the gateway to contact you before you let them in, this helps prevent unwanted callers and hawkers.
On the security front, electric gates have irreversibly geared motors making it difficult for burglars to force open the gates. Fitting electric gate opener ensures maximum protection and even greater security.
Having your gates automated increases the investment made to your property, with the extra style and exclusivity of automatically operating gates. It’s possible to automate existing gates too, so you have no need to purchase an entirely new gate.

Isn’t it Expensive?
We usually find that electric gates cost less than people imagine.25 years ago when automation was in its infancy it was truly the reserve of the mega rich to have their gates automated. Today with advances in manufacturing and technology, gate automation is within reach of many more people.
