Power supply reduces footprint
A new, modular 3-phase 24 V dc / 20 A power supply is designed for applications demanding small footprints, it is less than half the width of previous models. Footprint size has become one of the most important purchasing criteria for automation and controls components; by reducing the width from 6.3 in. to 2.76 in., the new switched mode unit is among the most compact power supplies available.<br/>
Siemens Energy & Automation Sitop Modular 3-phase 24V dc / 20 A power supply offers optional power security components, including selective circuit protection, to improve safety and efficiency.
Siemens Energy & Automation Inc. introduces its Sitop Modular 3-phase 24 V dc / 20 A power supply. Designed for applications demanding small footprints, it is less than half the width of previous models. Footprint size has become one of the most important purchasing criteria for automation and controls components, Siemens says, and by reducing the width from 6.3 in. to 2.76 in., the new switched mode unit is among the most compact power supplies available.
Wide input voltage range (360 to 550 V ac) covers the most common three-phase networks worldwide and helps the customer save more space. Unit converts industry standard three-phase 480 V ac into 24 V dc without added step-down transformers. Trouble-free load start up with high inrush current—required with dc / dc converters and direct current motors and solenoids—is achieved with extra power of 150% of the rated output current for up to 5 msec and power boost of 300% of the rated output current for up to 25 msec. If a parallel connection is required, the load sharing option can be selected, guaranteeing that each of the two power supplies, set up in parallel, provides the loads with 50% of required total current. Weighing 2.65 lb., the 93% efficient power supply also offers improved ambient temperature range, from 14 to 140°F, without de-rating. www.sea.siemens.com Siemens Energy & Automation Inc.

Annual Salary Survey
Before the calendar turned, 2016 already had the makings of a pivotal year for manufacturing, and for the world.
There were the big events for the year, including the United States as Partner Country at Hannover Messe in April and the 2016 International Manufacturing Technology Show in Chicago in September. There's also the matter of the U.S. presidential elections in November, which promise to shape policy in manufacturing for years to come.
But the year started with global economic turmoil, as a slowdown in Chinese manufacturing triggered a worldwide stock hiccup that sent values plummeting. The continued plunge in world oil prices has resulted in a slowdown in exploration and, by extension, the manufacture of exploration equipment.
