DC300WS
Revision 1-0 5
B Introduction and description
Read carefully before initial operation!
This manual shall help the user to get familiar with the product and its components and features. It shall pro-
vide information as accurately and completely as possible.
The manual as well as all documents has to be read and followed strictly before installation. Otherwise warranty
and guarantee can be cancelled partly or completely. Any liability on the part of Bicker Elektronik is excluded
for possible existing errors as well as non-compliance with the instructions for use and installation.
B1 Description of the product and its functions
The DC300WS is a powerful DC/DC converter with an output power of up to 300 W and a wide input voltage
range of 6 - 36 V. From an input voltage of 11V, full power can be drawn over the entire ambient temperature
range from -20 to +70°C without derating. Via the jumper (J3) the user can set the output voltage to 12 V,
19 V or 24 V before operation. A green status LED indicates that the converter is ready for operation.
The DC300WS also has the option of controlled activation of the device using active low logic (remote on/off)
via the input-side, separate spring contact connection (J6). Jumper (J5) must be set to use this functionality as
described in later chapters.
Sense lines can optionally be connected via the spring contact connection (J4) on the output side in order to
compensate the voltage drop at the output with long lines and high currents.
The DC300WS has several protections to safe the device from errors and defects. These include reverse pola-
rity protection on the input side, input undervoltage blocking, input overvoltage protection, overtemperature
protection and output-side overvoltage and short-circuit protection.
B2 Intended use
The device is a power supply for subsequent devices. It is designed for use in a suitable metal housing. When
installing, make sure that the DC300WS is connected to the housing via the supplied gap pad in order to ensu-
re cooling of the components underneath.
The ambient temperature specified in the technical details is the air temperature directly at the components
and must not fall below (minimum value) or exceed (maximum value).
The power supply is primarily designed for professional use in areas such as industrial control, communications
and instrumentation. It must not be used in devices or systems in which a malfunction could lead to serious
injuries or endanger human life.
The device is not designed to charge energy storage devices such as batteries, EDLC or lithium batteries. When
used as a charger, it can cause fire or endanger life and limb!
The device must be protected from being touched during operation because, depending on the power, the
temperatures can get too high and cause burns.
