Retronic announces highly efficient off-line LED drivers

June 1, 2010
Date Announced: 01 Jun 2010 Retronic introduces 2 off-line LED drivers with an output power of up 50W and up to 120W respectively. Target applications are LED street lighting as well as LED lighting in industrial and office buildings.These drivers are designed and manufactured in Europe to drive today’s most popular 1W LEDs off the mains grid at a constant current of 350mA meeting all relevant standards like EN55015/CSPR15 or EN61000-3-2. With a surge protection of up to 4kV they are robust enough for harsh industrial environments.Special attention has been paid to the efficiency and the lifetime of the circuitry by selecting high grade electronic devices. The efficiency is above 90% and with 60’000 hours lifetime the drivers match the expected lifetime of today’s LEDs.The 120W driver offers 3-channels with up to 50W and a total output of up to 120W. Each channel is independently dimmable with a PWM signal, making the driver also well suited for RGB applications. Depending on the forward voltage of the LEDs each channel can drive up to approx. 60 LEDs in red, yellow or amber and approx. 42 LEDs in green, blue or white.The 50W driver with 1 channel is targeted for LED lighting buildings and has been equipped with the very common 1-10V interface for dimming the LEDs. A version in plastic housing for mounting in suspended ceilings is available.To achieve the high efficiency the drivers are without galvanic isolation and should be installed inside the lamp and outside the reach of users.The drivers are available in sampling quantities now and full production will commence later this year.
