Description
The RACT20 series is a constant current dimmable AC/DC source for driving high power LED applications.
The phase angle dimming function works with leading or trailing edge dimmers. This driver is suitable for indoor
LED lighting systems and powers 5-15 high power LEDs or single LED arrays from 350mA up to 1A.
● 20W Dimmable AC-DC LED Power Supply
● 350mA, 500mA, 700mA or 1050mA Outputs
● Drives 5 - 15 High Brightness LEDs
● Deep Dimming to 0% *
● Active Power Factor Correction >0.95
● 3.75kVAC Isolation
● Output Connector to avoid miswiring
● 5 Year Warranty
