Features:

Constant current dimmable LED drivers are used for LED lights that require a fixed output current as well as a variety of output voltages. ES LD027D-CA06542-M28F Dimming LED Constant Current Driver (Constant Current Power Supply) Suitable for lighting with 650mA output regulated current. This class 2 constant current driver has Input Voltage of 120V AC, can produce 27-42V DC output voltage and 27.3W of output power. It is suitable for operation with main supply dimmer and also suitable for dry and damp locations. 
Note: Never use constant voltage driver instead of constant current driver, even if Voltage and mA are equal. 

How to Install ES LD027D-CA06542-M28F Dimming Constant Current LED Driver?

It is easy to Install constant current power supply, by following these steps, 

1. Make sure power is off.
2. Double check output current of the light and the driver.
3. Black and White color wires will be connected to 120V AC by splice the White color wire to Neutral (N) and the Black color Wire to Line (L).
4. Splice Red color wire to the positive (+) wire of the light and Black wire to the negative (-) wire of the light as well.
