C4800A - Schaefer Euro Series AC/DC Power Supply

Product Overview

Schaefer Electronics 6U DC-DC and AC/DC Converter Modules from 2.4kW to 5kW.

Schaefer Electronics robust design uses industrial grade components and provides a high density, space-saving solution for applications in industries such as railway controls and industrial equipment (onboard and track side) oil rigs applications, fuel cell applications, transportation, telecoms systems, process control systems, and power stations.

5kW Power Converter Offers Numerous Input Voltage RangesNine DC input ranges are standard: 10-16V, 20-32V, 40-64V, 50-80V, 80-160V, 160-320V, 320-640V and 450-800V. AC input options are 1- Phase 115VAC or 230VAC, as well as 3-Phase inputs of 3 x 200VAC, 3 x 400VAC, or 3 x 480VAC. Battery charging models are also available. Units feature single outputs in 10 standard ranges from 12-400VDC. 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.

All modules in the C/B 4800 Series feature a standard operating temperature of –20°C to +75°C (derate above +55°C), with an option for –40°C. All C4800 models have comprehensive protection circuitry including overvoltage, overload, short circuit protection, and thermal shutdown with auto restart. Efficiencies are up to 95%. EMI performance is to EN55022 Class A standards (Class B optional) with optional CE Marking.

Units are packaged in a rugged 6U x 56TE x 306mm (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.

INPUT OPTIONS
Option “i” (inrush current limiting): A thermistor is connected in series with the
input lines which changes its resistance from high to low when it gets hot. It does
not reduce the current surge if the input power is interrupted for a short period of
time not allowing the thermistor to cool down. Thermistors are fitted as standard
to all mains input models except for 1-phase input of models > 2.5kW.
Thermistors are available up to 45A. For higher input current an electronic inrush
current limitation can be offered.
Option “ie” electronic inrush current limiting An electronic circuit limits the inrush
current.
Option “sd” (series diode): A series diode protects the module against input
voltage of wrong polarity (additional power losses).
Option “ad” (anti-parallel diode): To avoid the power losses of a series diode a diode is
provided with opposite polarity in parallel to the input blowing an internal or external
fuse if the module is connected to a supply with wrong polarity.
Option “au” (auto-ranging) For standard dual AC input models the range of
115/230Vac is to be selected by connecting the input line to different pins on the
connector. With auto-ranging the unit senses the input voltage and provides
automatically the correct connection.
Option “p” (power fail): A signal (logic or relay) is given if the input voltage (AC or
DC) drops below the specified limit. In AC input units we sense the rectified input
voltage so that a power fail alarm will not be triggered if at light loads mains
power returns before the input capacitors are substantially discharged.
Option “r” (relay): A relay instead of a logic signal is provided for failure indication.
output options
Option “dd” (decoupling diode): For redundant operation the outputs of two or
more units are paralleled behind de-coupling diodes so that an internal fault of
one module does not affect the operation of the others. These diodes cause power
losses.
Option “cs” (active current sharing): An additional control circuit provides active
current sharing via an interconnecting wire between converters that operate in
parallel. Active current sharing should be used for multi-output units operating in
parallel.
Option “csi” (current sharing interrupt): Option "csi" will effect the removal of the
"cs" signal. Should there be an instance where a unit is not supplying the load,
then the effect of its "cs" signal is removed, and the load voltage is unaffected by
this condition.
Option “h1” (inhibit): A terminal connected to the negative input line also shuts off the
converter. This can also be used in conjunction with a thermal trip which shuts the unit
down.
Option “h2” (inhibit): Operation of the unit is inhibited if a voltage signal
(5V/10mA) is applied in reference to the negative line of the (main) output.
Option “rco” (reducing current limiting at over temperature) A circuit reduces the
current limiting level at higher temperature (to be specified).
Option “d” (DC-ok, one output): A logic signal is given if the output voltage (main
output in multi-output systems) is below the specified limit.
Option “m” (DC-ok, all outputs): In multi-output systems a logic signal is provided
if the voltage of any output is below the specified limit.
Option “ac” (AC ok) A logic signal connected to relay contacts is given if the
output voltage of an inverter is below the specified limit.
Option "y" (sys-reset): This logic signal is a combination of power fail and DC-ok
as specified for VME systems.
Option "r" (relay): A relay instead of a logic signal is provided for failure
indication.
environmental options
Option "t" (tropical protection):The unit is given additional protection by a heavy
coat of varnish on the printed circuit board(s) and components.
Option "c" (extended temperature range):The circuit is designed and tested for
operation at an ambient temperature as low as –40 °C.
Option "ms" (increased mechanical strength): Screws are secured by Locktite and
heavy components are fastened by ties and/or glue. Modules with the "ms" option
meet the standard EN61373 regarding shock and vibration.
mechanical options
Standard mounting "Eurocassette" pluggable module for 19" sub-racks 8
Option "w" (wall mounting): Module is screwed against a mounting plate for
installation in a cabinet. The load connections are typically a terminal block.
Option "cha" (chassis mount) Module is designed for installation to a structure or
within cabinet. Screw type connectors are supplied with the module.
Option "din" (DIN rail mount) Module is designed for DIN rail mounting to a
structure or within Cabinet. Screw type connectors are supplied with the module.
