The Rako RDC300 Module is a 12 or 24V low voltage DC dimmer for tungsten halogen or constant voltage LED’s. Depending on application, the input supply is from a separate 12v or 24v DC Power Supply. Brightness of each channel can be independently controlled by Rako scene-sender panels transmitting Rakom encoded radio signals.
All LED lamps need an associated driver unit to limit the current driving the LED. Some newer lamps integrate the driver into the base of the lamp but many use a separate driver unit . Often there are drivers not able to be dimmed however some options are now becoming dimmable. There are two types o f LED drivers;
1) Constant current , generally used for high wattage LEDs where the LEDs are wired in series.
2) Constant voltage where low wattage LEDS a rewired in parallel.
The unit requires a 12 or 24v DC power supply, normally supplied with LEDs.
