ELECTRONICS: TDK-Lambda has introduced the RFE1000 series; a new 1 kW single-output ac-dc power supply in an ultra low profile (only 1.61 inch high) 1U package for stand alone or distributed power architectures (DPA). These supplies are ideal for appli-cations requiring reliable 24V, 32V or 48V dc bulk power. Up to +20 percent and -10 percent output voltage adjustment is possible, enabling the RFE1000 to be used in a variety of customer specific applications. Operating from a universal input of 85 to 265V ac with PFC, typical applications for the RFE1000 supplies include communications, factory automation, test & measurement, robotics and RF amplifiers. Efficiency of up to 88 percent minimizes heat dissipation.The RFE1000-24, -32 and -48 power supplies can be used individually, or up to eight units can be connected in parallel to form an N+1 redundant power system with built-in ORing diodes. Each power supply has variable-speed cooling fans and can operate in temperatures ranging from 0 to 70C. The RFE1000 has a power density of 10.5W/in3 with dimensions of 12 x 5 x 1.61 inches.
Overvoltage, overcurrent and overtemperature protection are standard features, and for system monitoring there are opto-isolated signals for DC-OK, AC-fail and overtempera-ture warning, along with a LED indicator for DC-OK. Remote On/Off control is also stan-dard, as is remote sense. Other standard features include single-wire current sharing and an auxiliary 12V/0.25A output.
As well as being EN55022 and FCC EMC compliant (achieving class B conducted and radiated emission), the RFE1000 series meets UL/EN 60950-1 safety approvals and carries the CE mark. Harmonic correction meets the EN61000-3-2 standard, and the power supplies are backed by a two-year factory warranty.
The new RFE1000 family of power supplies is available now and priced at $295.00 each in 1000 piece quantities.
Truchard will be presented the award at the 2014 Golden Mousetrap Awards ceremony during the co-located events Pacific Design & Manufacturing, MD&M West, WestPack, PLASTEC West, Electronics West, ATX West, and AeroCon.
Robots that walk have come a long way from simple barebones walking machines or pairs of legs without an upper body and head. Much of the research these days focuses on making more humanoid robots. But they are not all created equal.
The IEEE Computer Society has named the top 10 trends for 2014. You can expect the convergence of cloud computing and mobile devices, advances in health care data and devices, as well as privacy issues in social media to make the headlines. And 3D printing came out of nowhere to make a big splash.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
