Start with the news release VXI introduces 200W switch-mode PSU from VXI Power, which we summarised at the time by saying "VXI Power has expanded its Oracle range of battery-backed switch-mode power supplies with the addition of a 200W model suitable for use in telemetry applications. ". Several months prior to that, we featured the news release Zigor UPS system eliminates power distortions from Zigor : "Zigor has launched the Volga Plus series of UPS systems for a variety of applications including telecommunications, data centres, networking and industrial uses. ".
In May 2010, we covered the news from Allegro Microsystems - take a look at Allegro develops multi-output LED RGB driver IC which says: "The A8512 from Allegro Microsystems is a multi-output white LED RGB driver IC for the LED backlighting of large-area LCD monitors and television screens. ".
Take a look also at the news release from TT Electronics Welwyn Components, W20 wirewound resistors for automotive electronics, as well as ULW series overcomes flaws of flameproof resistors from TT Electronics Welwyn Components, and Phihong develops SNMP-enabled mid-span device from Phihong.
