We offer numerous case styles and electrical configurations, giving us one of the most comprehensive LED driver offerings in the lighting industry.
AC LED Drivers are designed primarily for use with LED MR16 lamps. Hatch RS-LED Series AC LED drivers have been optimized to work with a wide range of LED MR16 loads and are recommended by top lamp manufacturers. Unique features of the RS-LED drivers include no minimum load requirement and flicker-free dimming down to 0%.
Constant Current LED Drivers are available in a variety of industry-standard form factors and are engineered with wide forward voltage ranges to accommodate most popular LED loads. Many constant current drivers are available in both 0-10V and phase dimming options.
Constant Voltage LED Drivers are available in a variety of industry standard form factors and are designed to meet stringent specifications for efficiency and quality. Most popular models are available in both 12V and 24V output.
LED Emergency drivers allow an LED fixture to be used for normal and emergency operation when used in conjunction with a switched or un-switched AC LED Driver. In the event of a power failure, the LED Emergency driver switches to emergency mode and operates the fixture for a minimum of 90 minutes.
LED Drivers are listed to have either a Class 2 or non-Class 2 output.
In a Class 2 output, the current, voltage and power must operate
within the following limits under normal operation and certain fault
• Maximum output DC voltage of 60 Volts (42.4 Volts for Canada
and 30 Volts for wet locations).
• Maximum rated output current of 5 Amps
• Maximum output power of 100 W.
General indoor luminaires predominately use LED Drivers with a
Class 2 output.
Non-Class 2 Output
Non-Class 2 LED Drivers have an output higher than the allowed
voltage, power or current levels specified for Class 2 Drivers, and
require fixture manufacturers to meet additional safety requirements
with the design of their LED luminaires.
Constant Voltage Drivers
Constant Voltage LED Drivers are typically used in signs. These LED
Drivers provide a constant DC voltage output, typically 12V or 24V.
The LED modules, connected in parallel, are designed to run at a
specified voltage and incorporates a current regulator to control the
current through the LED. Constant Voltage LED Drivers are ideal for
sign applications because of their flexibility to connect a wide range
of modules in parallel.
CAN AN LED DRIVER BE REPLACED AND
HOW INTERCHANGEABLE ARE THEY?
An LED driver of the same type (Constant Current or Constant
Voltage) may be replaced with a similar driver.
In general, our recommended approach to replacing an LED Drivers
is to consult with your local Universal Lighting Technologies’ LED
Select distributor (find your local distributor on our website) or contact
Universal’s Technical Support Team to discuss your application and
identify the optimal replacement driver.
HOW LONG WILL AN LED DRIVER LAST?
Various factors may affect the life of an LED Driver, but the factor with
the greatest impact is heat.
Similar to other power supplies (ballasts), the lifespan of the driver’s
internal components accelerate as heat goes up, causing the driver
to fail and the LED luminaire to stop working. Many LED drivers have
a Tc point indicated on their label. The temperature indicated at the
Tc point is the maximum allowable temperature for proper operation
of the LED driver.
Look at your LED Driver specification sheet. You’ll find two key
environmental parameters: Operating Temperature and Tc.
Operating Temperature is the ambient temperature in the air around
the driver inside of the luminaire, which is higher than the ambient
temperature outside of the luminaire. Tc is the maximum allowable
temperature for the LED driver, as measured at the Tc point.
There are additional factors than can shorten an LED Driver life
including power quality and transient voltages.
CHOOSING THE RIGHT REPLACEMENT DRIVER
An LED Driver can be replaced by another of the same type and
specification to meet the LED luminaire requirements. Early
generations of LED Drivers manufactured by the industry were odd
shaped, round or oblong. By contrast, today the interchangeable
shapes of LED Drivers offered by Universal Lighting Technologies
gives customers longevity and application design flexibility. Universal
offers a comprehensive portfolio of LED Driver options in multiple can
(shape) variations. Universal makes it easy for you to choose the right
replacement LED Driver for your facility.
When you are ready to choose a replacement LED Driver, it is always
a good practice to take pictures of the existing driver label and any additional labels applied to the sides of the driver
To determine the right replacement for an existing driver, there are
four pieces of information that you will need:
1. In what type of luminaire is the LED Driver being replaced?
While you may not need the exact dimensions of the driver, it’s
important to take note of the type of luminaire that the LED Driver
was installed in. Taking a quick measurement within the luminaire
will also give you the maximum size of the replacement driver
to ensure that it will fit properly. For maximum flexibility, look for
manufacturers that offer a variety of LED Driver Can sizes to fit
2. Is the LED Driver Constant Current or Constant Voltage?
Constant Current LED Drivers are found in everything from
outdoor, general indoor, specialty, and architectural lighting. If
there is a question, Constant Current lists voltage as a range
(examples: 2-42V, 14-30V, 8-19V, etc.) and a specific output
current or current range while Constant Voltage drivers list a
specific voltage like 12V or 24V.
3. What are the LED Driver Output specifications?
If the voltage and current requirements of the modules are not
listed in the luminaire, there are three specifications to look for -
Current (mA), Max Power (W), and the Voltage Range (V).
a. Current (mA): Equivalent to specified or up to 10% less
than the mA rating. Any less than that and there may be
a detectable difference to the light level in the fixture as
compared to the other installed fixtures.
b. Max Power (W): Equivalent to what is specified or higher.
Max Power refers to the available amount of Watts, not
necessarily what is used by the LED modules.
c. Output Voltage (V): Refers to the output range of the LED
Driver. This may be listed only as a max voltage.
4. Are there any control requirements?
Most of the Universal LED Drivers are equipped with 0-10V
dimming. A dimming driver can always be used for applications
where no dimming is required.
