RECOM Electronic’s Compact Size LED Driver: 30 Watt Constant Voltage with PFC

The RACV30 is the first of a new series of constant voltage LED drivers, ideal for powering LED strips and LED modules in applications such as cove lighting, signage, back lighting, channel letters, displays or under cabinet lighting. The input voltage range of 90 to 264VAC assures full functionality worldwide. The new drivers provide up to 30 watts and are available with outputs of 12VDC or 24VDC. The output voltages are closely regulated to compensate for varying loads or supply changes (2% max.) RACV30 drivers have active PFC and fully comply with EN6...

New AC/DC LED-Driver is Dimmable down to Zero and Flicker-free

TRIAC-dimmers were originally designed to dim incandescent filament lamps. The elimination of these lamp types increases the need for alternative dimming methods. The use of TRIAC-dimmers in LED-systems causes unwanted flicker, visible to the eye, due to phase modulation. This prevents linear dimming of LEDs down to zero. If existing TRIAC-Dimmers are to be used with LED-systems, a new type of LED-Driver is required.   RECOM releases with the RACT20-family a new generation of AC/DC-drivers, that can be dimmed linearly and without flicker f...
