0-10V Low Voltage LED Wall ELV Dimmer Switch

0-10V dimming is a lighting control method that – on direct current voltage (DC) between 0 and 10 volts – can produce light at varying intensity levels. 0-10V dimming is the simplest control system for lighting, providing smooth operation and dimming down to 10%, 1%, and even 0.1% light level. At 10 volts, the light will go to maximum power. At 0 volts, the light will dim to its minimum light level, although sometimes a switch is required to turn the lights off completely.

Single pole switches are most commonly used in home lighting circuits to control one or more lights or fixtures from a single location, such as the entrance to a room. Three pole or three-way switches are used to control one or more lights or fixtures from multiple locations, such as the top and bottom of a flight of stairs.

“ELV dimmer” doesn't mean the dimmer is electronic and low voltage, it means it's for dimming an electronic power supply of a low voltage light. An ELV dimmer cuts the trailing edge of the power wave, to reduce hum. So ELV, Trailing Edge and Reverse Phase actually all mean the same thing.
