Swiss current measuring company LEM has been busy, introducing three ranges of current measuring device at PCIM in Nurnberg: one closed-loop Hall-based, one open-loop Hall-based with digital outputs, and one for inductive for ac use on smart grids. LH current transducers are Hall-based, PCB-mounted, and can measure DC, AC and pulsed currents in three models: …

Cree has created an integrated-driver luminaire that delivers 143 lm/W – helped by its rather cool 5,700K white. The CPY-20L canopy luminaire produces 20,784 lm. The whole CPY Series is also available in 4,000K, and with a choice of flat or prismatic lens for different looks, and light distribution. US Class I, Division II hazardous-location …

Luminaire achieves 143lm/W

AVX has released a series of low-profile battery connectors for devices with pluggable modules that vertically mate with a base unit, designed to prevent end-users damaging the contacts. With a 2mm pitch, the 9155-800 Series is intended for >5,000 mating cycles in consumer, medical, industrial, and harsh environment applications. Contacts are gold-plated beryllium copper (BeCu), and the …

Toshiba has announced its next generation of super-junction deep trench semiconductor technology for power mosfets. Based on the DTMOS V process, devices are claimed to operate with lower EMI noise and with reduced on-resistance compared to previous DTMOS IV mosfets. As with DTMOS IV, V is is based on a single epitaxial process involving deep …

Linear Technology has created at three-phase ideal rectifier reference design. Using three of its LT4320 ideal diode bridge controllers and six n-channel mosfets, it is demonstrated on the DC2465 evaluation board. Power dissipation drops from roughly 1.2x the output current to 0.04x the output current if the correct mosfets are chosen, and cuts voltage loss to a few …
