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. OTTIMA OTM-TD20 Dimming LED Constant Current Driver (Constant Current Power Supply) Suitable for lighting with 470mA output regulated current. This class 2 constant current driver has Input Voltage of 90-130V AC, can produce 24-36V DC output voltage and 16.8W 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 OTTIMA OTM-TD20 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. Open the caps on the both side, loosen the screws on the green terminals.
4. Fasten the AC Wires to the side that displays Line (L) and Neutral (N).
5. Connect the light's positive wire to V+ and its negative wire to V-.
