istributed automation applications place wide- ranging demands on drive systems. Optimal solutions will, by necessity, be those that fulfil the functional and cost needs for a specific application. Available in a wide range of performance grades and with many upgrade options, SK 200E series frequency inverters from NORD DRIVESYSTEMS allow users to select customized solutions with features and costs that are tailored to their specific requirements.
The modular inverter series is
available in size 1 to 4 with a performance between 0.25 and 22 kW, cost-efficiently covering distributed applications ranging from simple control tasks to complex positioning.
Expansion options include external braking resistors and a separate 24 V power supply for stand-alone control voltage operation. .

external driver FET in buck, boost and buck-boost driver topologies makes it an all-in-one solution, capable of driving as many as 20 high current LEDs in boost mode with a high level of accuracy.
Employing patent pending control loops and single resistor high-side current sensing, the ZXLD1371 will deliver a typical output current tolerance of 1%, helping to produce improvements in brightness control and lamp luminance matching.
dynamic range, through separate 20:1 DC dimming and 1000:1 PWM dimming options, resulting in higher accuracy light control particularly at lower brightness levels.
To further improve the reliability of LED lamp systems, the ZXLD1371 provides thermal management of LEDs via a dedicated external thermistor input, which combined with fault diagnostic outputs reporting LED load and driver status, helps to increase LED longevity. Switching at up to 1MHz, the TSSOP-16EP packaged LED driver controller will also help minimize circuit size by reducing the value of the external inductor.
The ZXLD1371 LED driver controller is priced at $1.30 USD in 1k quantities. Diodes Incorporated

T electronics Optoelectronics Business Unit today announced
the OPA779 Series of display lighting for indoor illumination. The OPA779 delivers all of the benefits of LEDs – namely energy efficiency, longer life and light quality – in a unique tube assembly that makes it easy for manufacturers to make the leap from fluorescent to more energy- efficient LED based systems. Able to emit a uniform and consistent white lighting pattern within its length,
the OPA799 Series
provides exceptional lighting for retail display, architectural, under- counter, refrigeration, mobile food service, and point-of-sale displays.
“The OPA779 was designed through collaboration with our customers to produce a solid state lamp that not only provided the benefits of energy efficiency, but also met their needs for a low profile solution with excellent light quality,” said Roland Chapa, Product Line Director for TT electronics OPTEK Technology. “We supported those requirements by leveraging our expertise in optics, thermal management and electrical design. In addition, Optek has a proven track record with multi-chromatic tuning to generate a consistent and uniform white light that is critical for aesthetic applications.” The OPA779 Series delivers excellent light quality with a typical LED pitch of 1.5in, and a CCT of 5000K to 7000K. Total luminous flux, depending on device,
ranges from 40lm to 180lm, with a
maximum current drive range from 35mA to 175mA. Operating temperature ranges from 0°C to +70°C. The OPA779 series comes in two lengths, with the OPA779D-616 measuring 23.5 inches, and the
OPA779D-1169 measuring 46 inches. The OPA779D-616 and OPA779D-1169 solid-state lights can be used as a single unit or connected together in multiples to create scalable configurations. Optek will also build this product in custom lengths for unique applications.
