Advance Express

The following signs could be indications that a driver has failed or reached the end of its useful life:

1. The light output has noticeably dropped.
2. The light is flickering or flashing.
3. There is no light output and the wiring is correct & AC power is turned-on.  

Yes, the Advance Express program offers a list of commonly used drivers that  have a wide range of output current that can be configured to be suitable replacements  for existing drivers. It is important when choosing a replacement driver that the power is appropriately selected and the form factor and application are matched. Please refer to  cross reference list located here.

To determine a replacement driver, you will need to gather the information below on the existing driver. Much of this information can be found on the label of the driver to be replaced. Here is the information you will need:

1. The luminaire type (indoor, outdoor, industrial (high bay) or downlight)
2. The mains power (should be on the driver label)
3. The dimming interface
4. Output current (check label)
5. Output voltage of the driver (take highest number)
6. If the existing driver is a class 2 driver or not
7. Constant current or constant voltage
8. Physical size of the driver that is being replaced
9. If it is a downlight, is it a bottom entry or side entry connection?

9. If it is a downlight, is it a bottom entry or side entry connection?

To get started in determining the replacement driver, please follow the steps below:
 

1. Try to determine the type of luminaire it is: indoor, outdoor, industrial (high bay) or downlight
2. Ask the customer to send a picture of the driver AND the label.  OR
3. Go back to the original luminaire manufacturer and ask for replacement driver information for the specific luminaire.

Any driver that is designated as "Class P" or "Class P listed" is allowed to be field-serviceable without the need to contact the original luminaire manufacturer, as long as the replacement driver is the same or lower power.

When replacing a driver, it is important to know if the original driver is a class 2 or non-class 2 driver.

• Class 2: Driver meets the limitations of < 100W and  < 60V and has gone through additional verification during the agency certification to conform to Class 2 requirements
• Non-Class 2 (also sometimes referred to as Class 1): Class 1 drivers have higher wattage and/or higher voltage than class 2 drivers

RULE: you must replace a class 2 driver with another class 2 driver.

This is not allowed per regulations.  A Class 2 driver must be replaced with another class 2 driver.

Generally a non-Class 2 driver will exceed the power or voltage or current limitations of Class 2, so there will not be a matching Class 2 substitute. But, if a Class 2 driver is able to match the necessary power, current and voltage of the incumbent Non-Class 2 driver, it can be used as a replacement.

No, Non-Class 2 drivers can also be Class P.

The letter "I" or current or "Iout"  is the symbol for output current.

A driver is a constant current driver when it regulates the current directly for the specified range of LED voltage. Constant voltage drivers regulate a fixed voltage at the output, and the LED modules (or light engines) need to have additional on-board circuits to regulate the current in the LEDs.

To determine which type of driver you have, please refer to the list below:

• The driver will typically state if it is constant current or voltage or will state CC or CV, either on the product label or the datasheet
• If the driver specifies only one value for output voltage, it is a constant voltage driver (typically 24V or 12V). The LED module used with such a driver would usually call out this same voltage as an input specification, and usually also specifies a power rating. 
• If the driver specifies a range of output voltage (and either a single value or a range of output current) then, it is a constant current driver.

Generally most manufacturers indicate whether the driver is a Constant Current (CC) driver or a Constant Voltage (CV) driver on the product label or the datasheet.

It is important to replace a failed driver with a driver of equal or lesser output current.  To determine the output current:

• If it is an Advance driver, the current can be read with MultiOne program and programming tool (LCN9620)
• If it is not an Advance driver, contact the original luminaire manufacturer

For Advance drivers, the trailing digit in the part number indicates the generation of the driver. Generally, a higher generation is a suitable replacement for a previous generation. When replacing a product belonging to the same generation (with the same exact part number) you can use MultiOne Mobile for Android phones and use the cloning function to "copy - paste" the settings from the source driver to the target driver. However, note that a newer generation cannot be cloned from a previous generation. You will need to read the settings from the source driver and then program the replacement driver using the  MultiOne Engineering PC based software.

This is a TLED question. Please refer to the cross-reference guide located here.

Three most commonly used types of dimming are:

1. 0-10V dimming
2. Phase-cut (Leading Edge, Trailing Edge)
3. DALI

Refer to the dimmer on the wall. Go to the website for the specific dimmer and determine what type of dimming it supports:

1. 0-10V dimming
2. Phase-cut (Leading Edge, Trailing Edge)
3. TRIAC
4. DALI
5. D4i
6. DMX
