600W Rugged Power Converter Features Many Voltage Range Choices

Schaefer, Inc. introduces the C/B 2700 Series of 3U DC/DC and AC/DC converter modules and battery chargers.   The C/B 2700’srobust design uses industrial grade components and provides a highdensity, space-saving solution for applications in industries such asrailway controls and communications equipment (onboard and trackside),military applications, oil/gas processing, fuel cell applications,transportation, telecommunication systems, process control systems,and power stationsThe C/B 2700 Series topology delivers up to 600W at any DC input from18VDC to 380VDC, with six input range choices.  AC input options aresingle-phase 115VAC or 230VAC, as well as a three-phase input of 3 x200VAC.  Battery charging models are also available.  Units featuresingle outputs in nine standard ranges from 8VDC-290VDC.  All outputsare adjustable and tightly regulated to 0.2% or better (load) and 0.1%(line).  Custom input and output ranges are readily available,typically not impacting delivery and at no additional cost.Convection cooled, these converters perform from  –20°C to +75°C(derate above +55°C), with an option for –40°C operation.  All modelsfeature full electronic protection and up to 92% efficiency.  EMIperformance is to EN55022 Class A standards (Class B optional).Units are packaged in a rugged 3U x 28TE x 226mm (HxWxD) module withan optional wall mount configuration.  Other options include inputinrush current limiting, DC input reverse polarity protection, outputparallel/redundant operation, remote on/off, Power Fail/DC-OK alarms,system reset, and programming/monitoring functions.  Furthermechanical “ruggedization” and extended environmental operatingconditions for higher temperatures and humidity is also available.• DC input: 18 - 380 V • AC input: 115 / 230 V, 47 - 400 Hz • DC output: 8 / … / 250 V
