Operating at an ambient temperature of up to 60°C without a heatsink or forced cooling, Tracopower’s TSR-1 Series 1 A switching regulators operate at a full load efficiency of up to 96%. The 9 models offer input voltages from 4.75 VDC to 32 VDC, output voltages from 1.50 VDC to 15 VDC, output current of 1 A, and direct operation from a 24 VDC bus voltage. The instruments act as
The world of computer technology has two incompatible characteristics. First, many computer systems have long lives. Second, students and many engineers pay attention to only the latest technologies and they believe old technologies have died out. The "yesterday's-fashion” phenomenon has applied to the Ada programming language, too. If engineers have heard of Ada at all, they may assume it is an old US Department of Defense technology that disappeared long ago.
Most power-conversion applications require a DC source, which uses a rectifier that draws non-sinusoidal line currents. As a result, line-current harmonics have become a significant problem and they lead to overheating of transformers and inductive equipment, degradation of system voltages and increased stress on components. In addition, stringent limits imposed on harmonic currents by international groups make the need to improve power quality even more important. Power-factor correction (PFC) can help solve these problems.
Pairing with FANUC servos, GE Fanuc Intelligent Platform’s PACMotion motion controller module controls up to 4 axes plus a master axis in motion applications in the packaging, assembly, metalworking, and printing industries. The component uses PACcore multi-processor architecture bridged by virtual dual port memory and a PCI backplane to decrease the degrading of

The recent Energy Star controversy must inevitably be discussed in a broader context. To sum up current events: on June 2nd, the EPA violated Energy Policy Act (EPACT) 2005 by releasing a “technical amendment” (version 4.2) to their Energy Star solid state lighting criteria without consulting “interested parties” (i.e. industry).
With its 90-265 VAC universal input and active PFC, the 400W TMPC-400 ATX PC power supply can be used globally without changing input settings.
