FAQ for LED Dimmable Drivers

What operating systems are supported?

The Progamming Utility will run on Windows XP SP3, Windows Vista SP2 or Windows 7.

Where can I get the Programming Utility?

You can download it from the nmbtc.com/lighting/install page.

How do I program the CLSD Series of Dimmable Drivers?

Once you have the CLSD004 or the CLSD005 Programming Kit you can then refer to the Programming Instructions.

Where can I get additional Programming Kits?

You can order the Programming Kit (CLSD004 or CLSD005) from an authorized NMB Distributor. Please check inventory status at our Distributors at "www.nmbtc.com/lighting".our parts listing to see our authorized Distributors.

How do I connect the dimming feature on the driver?

Please refer to the wiring diagram on the Dimming Information page.

What do I do with the dimming wires if I do not plan to use the dimming feature?

Cover the exposed wire ends with insulation tape.

The Programming Application will not open on my system. What is the cause of this problem?

Please ensure that you are using a supported operating system, and that the setup installation has been completed successfully.

Why do I need to download the Microsoft .Net Framework 3.5?

The Programming Utility requires Microsoft .Net Framework 3.5 to run.

Why do I need to disconnect power while the programming the driver?

Although the CLSD000 Driver Series includes circuit protection, for safety reasons and to ensure no damage to the driver, it should be disconnected from the power source before programming.

When I connect the Programming Box(CLSD004 or CLSD005) I get an error message stating that "the application failed to install properly." What do I do?

Please ensure that you are using a supported operating system, and that the setup installation has been completed successfully.

When I connect the Programming Box(CLSD004 or CLSD005) I get an error message saying that "the hardware failed to install properly." What do I do?

Using the Unistall Routine, uninstall the Driver. Then reinstall the Driver making sure the Programming Box is not connected.

Do I need to reattach the tape strip over the hole in the driver after I have finished programming?

Can I program the driver more than once?

Yes, it can always be reprogrammed, as long as AC power is not connected during programming.

How accurate is the LED current compared to the programmed current level?

Nominal : ±10%

What is the output voltage at no load?

The no-load voltage (maximum voltage) is located on the product label and CLSD series Data Sheet

Is there any de-rating at high operating temperatures?

Unlike many of our competitors, the CLSD001 does not have a power de-rating when operating above 50°C.

Can I use a resistor or potentiometer for setting the dimming level?

Yes

It the CLSD Series a Constant Voltage or Constant Current device?

Constant Current.
