Courtesy: Phoenix ContactThe Step UPS from Phoenix Contact is a compact uninterruptible power supply with an integrated battery. The Step UPS provides standby power for short-term power losses in low-current applications.

The Step UPS has a 3 A output current, and corresponds with Phoenix Contact’s Step power supply with 4.2 A nominal current. At 108-mm wide, the Step UPS requires minimal space on the DIN rail. When used with the corresponding Step power supply unit, they occupy 198 mm. 

The Step UPS comes in both 24 V dc and 12 V dc versions with an integrated lithium-polymer rechargeable battery. The 24 V version has an input range of 22.5 to 29.5 V dc, while the 12 V version operates between 10 and 16.5 V dc. 

The modules contain status LEDs indicating the unit’s operational condition. The status may also be communicated to a supervisory control system through the integrated status contacts. Additionally, the battery runtime can be adjusted via a rotary dial to prevent the battery from being overly discharged. The amount of back-up time available depends on load currents connected to the buffer module, but can range between 12 and 53 minutes.

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.
