3.4.1 Power supply unit
The module ETCHN003 is used for the power supply of an ETC island and
transfer module for the CAN bus with multiline system structure.
ƒ Input voltage 18 ... 30 V DC
ƒ Output voltage 5 V DC (max. 3 A) and 24 V DC (max. 2 A)
ƒ Short−circuit and undervoltage protection
ƒ CAN−BUS In
ƒ Bus terminator can be added
ƒ Transfer module for multiline module structure
)
Note!
ƒ Only one power supply unit is possible per ME bus. The
attachment of serveral power supply units (parallel
connection) to one ME bus is not permitted.
ƒ The module is protected against short circuit and reverse
polarity. During a short circuit or overloading of the internal
24 V supply on the ME bus the power supply is interrupted.
ƒ The 5 V supply is protected by the internal protective circuit of
the DC/DC converter.
ƒ Each external connection is protected up to an electric
strength of +32 V. This protection effective for a faulty
connection of the module and only if the supply cable includes
a circuit braker 6 A Type B which will trigger, if necessary.
