Power converters

Power converters offer packaging, mounting and input choices; remote sense, comprehensive overvoltage and overload protection circuitry are standard.


The C300 and B300 series 150W dc/dc converters, ac/dc power supplies and battery chargers offer packaging, mounting and input choices. The C300 dc/dc product line includes seven dc input ranges: 10-16 V, 18-36 V, 36-75 V, 45-90 V, 80-160 V, 160-320 V and 320-380 V with 10 single-output voltages ranging from 5 Vdc to 220 Vdc. The C300 ac/dc series offers the same output voltage ranges from a choice of 110 Vac, 230 Vac or 115-230 Vac inputs. The BP200 series battery chargers provide output voltages ranging from 12 Vdc to 290 Vdc. Requests for custom output voltages can be accommodated.
Efficiencies range from 70-90% and all models feature tight line and load regulation. Remote sense, comprehensive overvoltage and overload protection circuitry are standard. Options include dc input reverse-polarity protection, redundant operation, remote on/off and temperature-compensated charging voltage.
Units use industrial-grade components that achieving an operating temperature range of -20 to 75 C; extended temperature to -40 C is optional. EN55022 Class-A EMI is specified (optional Class B), as well as immunity to EN61000-4-2, EN61000-4-4 and EN61000-4-5 Level 3 standards. The series offers four mechanical configurations of a 19-inch Eurocard mounting, wall mounting, chassis-mount packaging or DIN rail mounting package.

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.
