600W Rugged Power Converter Features Many Voltage Range Choices

Description

Schaefer, Inc. introduces the C/B 2700 Series of 3U DC/
DC and AC/DC converter modules and battery chargers.   The C/B 2700’s
robust design uses industrial grade components and provides a high
density, space-saving solution for applications in industries such as
railway controls and communications equipment (onboard and trackside),
military applications, oil/gas processing, fuel cell applications,
transportation, telecommunication systems, process control systems,
and power stations

The C/B 2700 Series topology delivers up to 600W at any DC input from
18VDC to 380VDC, with six input range choices.  AC input options are
single-phase 115VAC or 230VAC, as well as a three-phase input of 3 x
200VAC.  Battery charging models are also available.  Units feature
single outputs in nine standard ranges from 8VDC-290VDC.  All outputs
are 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 models
feature full electronic protection and up to 92% efficiency.  EMI
performance is to EN55022 Class A standards (Class B optional).

Units are packaged in a rugged 3U x 28TE x 226mm (HxWxD) module with
an optional wall mount configuration.  Other options include input
inrush current limiting, DC input reverse polarity protection, output
parallel/redundant operation, remote on/off, Power Fail/DC-OK alarms,
system reset, and programming/monitoring functions.  Further
mechanical “ruggedization” and extended environmental operating
conditions for higher temperatures and humidity is also available.
