TRIAC Dimming: Triode for alternating current (TRIAC) dimming is used to control high-voltage dimmable power supplies such as Magnitude Dimmable Power Supplies. These dimmable power supplies work by varying the power on the AC input side of the power supply by means of a TRIAC dimmer. This change in power on the AC input side will vary the voltage on the DC output side and control the intensity of the LEDs. TRIAC dimmers are common hardware store and household dimmers,which include brand names such as Lutron and Leviton.
Pulse-Width Modulation Dimming: Pulse-width modulation (PWM) dimming can be used to control dimmable power supplies. This type of dimming control adjusts the output current based on the duty cycle. As the duty cycle increases, current will increase and the LEDs will be brighter. Conversely, if the duty cycle decreases, the current will decrease and the LEDs will be dimmer.
DALI is the abbreviation for “Digital Addressable Lighting Interface” which is illumination control communication protocol opened in the world. DALI dimmable driver signal adopts DALI technique, and combines digital lighting control system, which realizes full digitalization LED control product line.
Nowadays, most of our Dimmable Led Drivers have passed the ETL CE Rohs listed. They are:
triac dimmable constant voltage LED drivers (12V & 24V type, 12W 20w, 24w, 30w, 36w, 48w, 60w, 80w, 96w, 120w, 150w, 200W)
0/1-10V dimmable constant voltage LED drivers (12V & 24V type, 20w, 30w, 45w, 60w, 80w, 96w, 120w, 150w, 200W)
DALI Dimmable Constant Voltage LED Drivers (12V & 24V type, 30w, 45w, 60w, 80w, 96w, 120w, 150w, 200W)
