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 Electric Connection arrived on time as promised. They were pleasant and efficient, and they took care with our room furnishings by covering the furniture and our flooring as needed. They cleaned up completely when the job was done. We will definitely use them again for future electrical projects.

Your electric bill may not be a problem for you, but wouldn’t it be nice to have a few more dollars in your pocket every month? Imagine if you could save even ten dollars every month. You could set it aside and put towards a fund to buy something that you have been wanting or buy an extra latte. No, it isn’t a lot, but you never know when a little extra cash will come in handy. And, it isn’t just ten bucks. It could end up being much more if you follow these tips presented by your Pasadena electrician. The team at The Electric Connection is here to help you find out how you can save.

*Your biggest energy hog is going to be your air conditioner or furnace in the winter. You don’t have to cook or freeze, but you can turn it up a bit in the summer and down a bit in the winter. Throw on a comfy sweater during the winter so you can keep your furnace setting lower. In the summer, keep the blinds closed and run a ceiling fan to help stay cool without cranking the AC up.

*Lighting is the second biggest use of electricity in your home explains an electrician. Pasadena homeowners can slash their electric bill by turning off lights when not in use. Switching to LEDs is another quick and easy way to save some cash.

*Turning down your water heater a few degrees will also save you a great deal of money. If you are not sure how to do this, call an electrician in Pasadena to take care of it for you. Most people are heating water to a temperature they can’t actually use and end up turning on the cold water to cool it down.

These three quick ways can save you money every month. You will see the savings on your next electric bill. Give The Electric Connection a call if you have any questions or need help taking care of any electrical issues.
