Magnitude’s SR412 is a high-efficiency PWM low voltage driver used to power LED strings at a true constant current, operational with dimming control and small enough to be incorporated into OEM products.
MD-SR412 450mA Constant Current LED Driver 12VAC Input
The driver fits between the transformer and the LED lights to feed the LEDs constant current, even when the source voltage drops. The result is a system in which the LEDs perform to the manufacturer-specified brightness in lines of almost any length.
Due to its ultra-small size, the driver can be used in any LED application. It is a true retrofit device which will also work in existing systems fitted with magnetic transformers.
