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.

The electrical field is one that has seen a number of remarkable discoveries over the decades. One very important lesson has been the aspect of grounding of electrical currents. It’s true that we need electricity for almost everything in our daily lives and can’t even imagine a world without it. However, it continues to be one of the most dangerous elements on earth. If you haven’t already properly grounded your home’s electrical systems, you are taking a significant risk by not doing so.

Every electrical circuit has an active wire which supplies power; there is also a neutral wire which is responsible for carrying the power back. There is a third wire (grounding wire) that can be attached to the power outlets & the electrical appliances and devices; this wire is connected securely to the ground in your breaker box.

This third wire is the additional path that the electrical current can pass through to be safely returned to the ground, in case there is a short circuit; this prevents any harm being caused to anyone. In the event that a short circuit occurs, the current flows through into this grounding wire and it’s when you notice a tripped circuit breaker or a blown fuse in the electrical main board on your property. If this wire hadn’t been grounded, it would have resulted in a fatal shock.

This is one of the most important reasons to ground electrical currents. It’s the best way to protect your family members from electrical surges when they are operating any electrical appliances in the house. In case a lightning strike causes an electrical surge on your property it can result in extremely high electrical voltages in your system. When the wiring has the proper grounding, all the excess electricity gets diverted into the earth, rather than burning everything that’s connected to your electrical system.

When your installation is grounded, it becomes very easy for the power to get directed exactly to where you need it; this allows the electrical currents to efficiently & safely travel across your home’s electrical system.

A properly grounded system makes it much easier for the power to be distributed in the right amount to the right places. This plays a significant role in ensuring that there is no overload in the circuits. The earth becomes the common reference point for all the different sources of voltage in an electrical system.

One of the primary reasons why grounding is extremely effective in keeping you safe is because the earth is an excellent conductor, and electricity always takes the path that has the least resistance. When you ground your electrical system, you are giving it a path that it can easily take, rather than into you; this can potentially save your life.

If your home’s electrical system isn’t properly grounded, you are just risking the appliances and equipment that are connected to your system, being burnt beyond repair. If the situation gets out of control that can also result in a fire risking your property and causing physical injury, sometimes even death.

If you aren’t sure about whether your electrical system has the right grounding, its best to call in a reliable local electrician to get it checked thoroughly. We at AllRound Electrical 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.
