wehopower | Constant volatge Led Drivers &Power Supply

When looking for a WeHo power supply for LED lighting it is easy to get lost in the many different options available. First, it is a good idea to know the specific needs of your project. Often, power supplies are wrongly chosen for an LED project which leads to failure. In order to cut out any issues use the quick checklist below when looking for an LED power Supply.

What to consider before selecting a power supply?

How will I connect my power supply?

A simple outlet plug or directly wiring into AC lines?

Will the power supply fit in the desired space?

Make sure to check the size of the unit to make sure you have room for it.

Can I use a power supply outdoors or in a damp area?

Luckily there are many Waterproof power supplies and drivers, just look for the IP65 rating!

Do I want to be able to dim my LED lights?

If dimming is needed, make sure to choose a power source that has dimming capabilities.

Lastly, does my application require any other functions?

Examples: PFC, Over voltage protection, Over temperature protection, UL recognized, etc.

If you are unfamiliar with how LED power supplies operate and their specifications, the best place to start is at our first post in this series – LED Power Supplies 101.

When looking for both an LED driver and power supply brand to trust, look no further than WeHo. With a failure rate at less than .02% in 2016, WeHo has continued to make some of the most reliable power supplies in the world. After completing the checklist above and knowing what you are looking for, check out the options below!

WeHo Power Supply and Driver Catalog

This quick selection guide will go through the many categories and options offered by WeHo . If you are still unsure about your LEDs properties then you need to check the power input that your LED needs. If there is any confusion it is good to backtrack and find your LEDs properties and whether you need constant voltage or constant current supply.

LED Constant Voltage Power Supplies

Does your LED require 12 volts DC or an alternate DC voltage? Are you unsure of how to power your LEDs when common household electricity is AC voltage? What you will need is a standard AC to DC switching power supply, taking AC line voltage and outputting a constant DC voltage. There are power supplies that plug straight into a wall receptacle or units that wire directly into the main AC lines. WeHo offers a variety of output voltages, so when working with a pre-built LED lamp that needs a certain constant voltage, look for the rated input power needed and you are good to go. A good example of a product needing a constant DC voltage would be our 12V LED flex strips.
