LED Drivers

LED Drivers have one unique feature over old style transformers.  They switch off (electronically) if the load exceeds its capacity.  Without this feature, Ohms law explains that when the load is increased, the voltage drops. This is a critical factor for an LEDs life.

There are also two types of LED- those that require Constant Voltage (CV) and those that require Constant Current (CC).

We stock and sell 12VDC CV Drivers, LED Control gear, and our entire range of LEDs.

LOAD

LEDs are voltage sensitive, so, rather than drop below a defined voltage, which could cause damage, the Driver will switch off, and then back on once the load falls to within capacity. This is why an overloaded LED circuit will flash off and on.

LED Drivers are often called Power Supply Units (PSU), Drivers, Transformers, or Wall adapters.  As long as your power supply is the ‘switching’ type it can be used as an LED Driver.

We recommend never loading a Driver at more than 85% of its capacity. This is because heat creates electrical resistance.  More resistance requires more current, and the 15% safety margin should prevent overloading, but beware. An LED Driver can operate at above 60 degrees Celsius. That’s way above what is comfortable or safe to handle, so we recommend heat sinking or positioning in a ventilated space.

There are a number of other features available on Drivers.  But, they cost more too. They are usually specific to a requirement like nonflickering when dimming.

WARRANTY

Our switching-type Wall adapters attract twice the industry standard warranty, with a simple and full replacement policy of 24 months from the purchase date.   All other electronic components, including our “Sasign” Branded Waterproof LED Drivers, are offered with a full FIVE-year replacement warranty, if purchased after March 1, 2020.
