The LB130 Series, a single output, conduction cooled, LED power supply has been launched by SL Power. The company claims that this is the first conduction cooled LED power supply to deliver 130W at 90% efficiency in a 3” x 5”x 1.3” package. The LB130 is a single output power supply that is ideal for high intensity entertainment applications such as stage lighting and theatre control systems due to the ability to operate efficiently in extreme temperature conditions and tight spaces.

The LB130 is designed to operate from -40? to 70? providing optimum thermal performance. Delivering 130 watts at 70? ambient, the LB130 power supply is the smallest in the industry featuring conduction cooling that eliminates space and associated costs needed for fans. Meeting EN55015 standard for Electro Magnetic Compatibility (EMC) immunity and Class B Conducted EMI, the LB130 does not require an external Electromagnetic Interference (EMI) module – saving valuable space and costs. In addition, the power supply can turn on at -40?, eliminating the need for a costly heating element. The LB130 also meets the European lighting harmonic requirements from 130 Watts to 5 Watts, enabling the lighting fixture to comply with EN61000-3-2 class C for 100% to 0% dimming. Featuring over 50,000 hours of life expectancy at 70? ambient temperature, the LB130 provides the key element for a LED solution over traditional lighting.

“Our close work with our lighting customers led us to design and develop a power supply solution that will meet the needs of high demand global applications,” said Maggie Nadjmi, product manager for SL Power Electronics. “LED lights bring a more energy efficient solution to a myriad of commercial and industrial applications. We believe the products powering these lights should be equally as efficient. This is why we have designed our new LB130 model that offers the highest efficiency, superior EMI performance and wide temperature range at a very attractive cost.”

The new model features a universal input of 90 to 264Vac and 56V output voltage. Moreover, the LB130 Series high power density power supply is ideal for backlight, panel and architectural lighting as well as light controllers needing a highly reliable and energy efficient power solution in a small form factor at an affordable cost.

Featuring a three-year warranty, the RoHS compliant LB130 model has more than 50,000 hours of lifetime expectancy operating at 70? and has EN/CSA/UL/IEC 60950-1, 2nd Edition approval markings. Available now through SL Power’s extensive distribution sales channels, OEM pricing starts at $100 each for 500 piece orders.
