constant-current LED driver or constant-current driver is used to regulate the amount of current that is supplied to an LED or LED array to maximize LED lifetime. If current is not regulated, LED brightness can fluctuate and life span can be shortened. The constant-current driver is used for LEDs or light fixtures that require a stable output current and operate within a range of voltages. Most finished LED products already have a constant-current driver or resistors to regulate current. If you’re building an LED fixture or replacing a constant-current driver, it’s important to verify that the output current and voltage of the driver is compatible with the LEDs’ current and voltage. If your LED product already has a constant-current driver or uses resistors in the LED array, you might need a constant-voltage power supply.

If your LEDs are dimmable and you want to change their brightness, choose a Magnitude Dimmable Power Supplies. These dimmable power supplies work by varying the power on the AC input side of the power supply by means of a TRIAC dimmer. This change in power on the AC input side will vary the voltage on the DC output side and control the intensity of the LEDs. TRIAC dimmers are common hardware store and household dimmers, which include brand names such as Lutron and Leviton.

Pulse-Width Modulation Dimming: Pulse-width modulation (PWM) dimming can be used to control dimmable power supplies such as Mean Well LPF Series. This type of dimming control adjusts the output current based on the duty cycle. As the duty cycle increases, current will increase and the LEDs will be brighter. Conversely, if the duty cycle decreases, the current will decrease and the LEDs will be dimmer. Pulse-width modulation for these drivers is based on a 10-volt signal level with a frequency between 100Hz-3KHz. The MLD-5A are compatible for this application.

Resistive Dimming: Resistive dimming can be used to control dimmable power supplies such as 12-Volt Mean Well HLG-40-240 Series or 12-Volt Mean Well HLG-600 Series or here.

The efficiency of a power supply or driver indicates the percentage of power that goes toward making your LED product function. An efficiency of 80 percent or higher is recommended for operating LEDs. 

When choosing a driver or power supply, the size of an LED product’s housing or area of installation is important. If you wish to put a constant-current LED driver inside of a product, the driver must be small enough to fit in the product’s housing. Similarly, if the driver or power supply is used outside of the product’s housing, it should fit the area of installation. Drivers and power supplies are available in a variety of sizes to suit your needs.

A Class 2 driver or power supply is in accordance with limited power levels defined by the National Electric Code (NEC) and fulfills the requirements of Standard UL 1310. Output is limited to 60 volts DC and 100 watts. Because power sources with this rating have limited output, it might not be possible to power as many LEDs or lights as those that don’t have a Class 2 rating. However, these power supplies and drivers provide protection from fire and electric shock.

A Class II rating refers to a double insulation layer between AC input and DC output wires. These drivers and power supplies do not require a ground connection.

When it comes to electrical tasks in yousitur home, it’s never a good idea to turn them into a DIY project. Electricity is a very necessary and useful utility, but can be extremely dangerous too and it’s crucial that you call in a certified, skilled and insured electrician to handle the job for you. Look for a professional and reputed company that provides 24/7 services and keep their number easily accessible at all times; this will ensure you get prompt services exactly when you need them. Here we discuss in which situations you should call in an emergency electrician to tackle the job for you:

This is extremely dangerous and you should immediately turn-off the circuit breaker that you feel is connected to that wire. Do not try to repair this yourself as there could be a chance that the circuit breaker you turned off isn’t connected to that particular room wire at all and this exposes you to the risk of electrocution.

This is a situation you shouldn’t take lightly at all. It’s important that you keep all your family members and pets away from that room and switch off the circuit breaker you think is connected to that wiring line. If you have any water pooling, puddling or accumulated (as in a flood situation), call in a skilled electrician to check all the wiring and address the problem without delay, as this is a major electrocution risk.

It’s not often that a home will lose power completely, while there is no similar problem in the neighbourhood. However, if the power does go out only in your home, quickly check with your neighbours and check whether the street lights have also lost power. If everything seems to be alright there, you may have a major electrical problem on your hands.

In all these situations, do not try to find out what the problem is; call in a licensed, local electrician to inspect the wiring and other electrical fittings and fix the problem. The point we are trying to make here is that if you in any way feel that an electrical installation or appliance is unsafe, call in an electrician without delay.

The one way to reduce the chances of an electrical problem from occurring is to get regular electrical maintenance done. The company you hire for the job will send out skilled professionals at pre-decided schedules to conduct a thorough check on the wiring. In case any potential problems are noticed, you will be informed about them and they will be addressed without delay. This reduces the chances of major electrical problems surfacing out of the blue.

We at Allround Electricals will check the system carefully and check it for any other potential faults as well. For more information, contact our friendly team at this number – 1300 169 263. You can also write to us at this email address.

Common Residential Wiring Problems

There are many wiring problems that your home can encounter throughout the years. Any residential wiring problems in Chester County, PA require immediate attention. While there are a variety of problems your home can experience, here are some of the more common code violations that could result in worse problems later on.

Junction Box Uncovered

Wires connect to one another at the splices which are housed in the junction box. Without a cover, wires could accidentally be damaged or someone could be shocked. This is a code violation and is a danger if wires are within reach. A new cover for the box is inexpensive.

Flickering Lights

If you notice your electrical lights flickering when it is windy outside, your home probably has frayed wiring in the weather-head which causes a short when the cables move. The weather-head is the fitting where overhead cables from the power line enter the house. This is a major danger, as it can arc and result in a fire. This is a problem that needs to be addressed by your electric utility provider.

Lack of Electrical Outlets

If your home has too few outlets, you are relying on power strips and extension cords. This results in minimal risks as long as you use extension cords that are 14-gauge or more, meaning they are heavy duty. Undersized cords can overheat and cause a fire, so it is wise to go ahead and have a professional electrician install additional electrical outlets.

Failing to have GFCIs

Ground-fault circuit interrupters (GCFIs) can shut down a circuit fast, within 4 milliseconds. While this is grandfathered in and is not a code violation. Codes for newer homes require GFCIs on all outdoor outlets, basement and garage outlets and within four feet of any sink. If your home does not have any GFCIs, you should add them to ensure safety.

Whether you are a do-it-yourselfer who feels confident in most household chores, or you are clueless about most household tasks, it makes sense to learn the basics when it comes to electricity. While you will want to contact an electrician in Santa Monica (Click Here), such as one from The Electric Connection, for any direct electrical work, you can at least have a better idea about the basics and be able to have a conversation when the electrician Santa Monica comes out to take care of your electrical repairs or installation. Learning these basic electrican terms is a great way to broaden your understanding of electricity.
