July 25, 1999 by Jeff Shepard

Schaefer Inc. (Ashland, MA) has introduced the C5600 Series of 6kW, 6U/9U high, 19" rack compatible dc/dc and ac/dc converters. The C6500 Series is available with dc input voltages from 20-900Vdc, as well as ac input voltage ranges of 93-264Vac. Three-phase ac input voltages from 320-530Vac are also available. The C5600 Series can be purchased with a Power Factor Corrected front end. Outputs are available from 4.5-400Vdc. All outputs are adjustable and fully regulated to 0.2 percent or better (load) and 0.1 percent.All units in the C5600 Series have remote sensing, over-voltage protection, and current-limit protection on the output. Zero switching allows for efficiency as high as 93 percent, depending on input and output levels. Operating temperatures available include -20 to +75 degrees C and extended range -40 to +75 degrees C.The C5600 is packaged in a 6U/9U x 19" 360/460mm chassis and incorporates a terminal style wiring interface. Options available to allow highly reliable operation under virtually any environmental conditions include: increased mechanical strength, tropical protection, inrush limiting, temperature controlled forced air cooling, decoupling diodes for parallel operation, inhibit, power fail/dc-ok, system reset, active current sharing and wall mounting.Typical applications include on-board locomotive controls and communications equipment, telecommunication systems, process control systems, power stations and virtually any other high power requirement. Pre-configured rack solutions are available. Mechanical and electrical modifications to standard modules are available upon request. In addition, Schaefer can design and manufacture custom solutions. Pricing for the C5600 Series starts at $2655 each in quantities of 100. Significant OEM quantity discounts are available.
