Protection and monitoring equipment:
Overload protection U-I characteristic curve current limitation
Activation point: 1.1 x I nom
Sensor line operation Wrong sensor line connections do not
damage the converter.
In the event of a sensor line break the
output voltage is limited to a maximum of
120% of the nominal output voltage.
1 V adjustable.
Overtemperature protection Shut-off if temperature becomes too high,
automatic reactivation when temperature
Varistor in output as additional overtemperature protection.
Signalling relay in output with volt-free changeover contact.
Output voltage monitored for undervoltage and overvoltage.
Operating temperature range -25°C - 70°C (derating from +50°C with
Cooling From built-in fan, temperature controlled

Control, operating and indicating elements:>
Indicators There is an LED at the connection sidefor indicating
the presence of the input voltage.
A second LED indicates output voltage within range.
A third LED indicates temperature too high
Output voltage adjustment The output voltage can be adjusted using
a potentiometer at the connection side
The adjusting range is +5% -10%.
Parallel switching capability 3 units can be operated in parallel to
An internal current sharing circuit is
mainly responsible for this.
Sensor line operation 1 V, adjustable
10mm² screw terminals for input and 4mm² for output (double)
1.5mm² screw terminals for signalling
Dimensions: WxHxD, 225 x 125 x 125
The standard version of the converter is housed in an aluminium case.
The screw terminals enable fast and simple connection.
The 125mm height means the converter can be also installed in a 19" rack.
The surface of the converter is finished in white chrome.
A ruggedised version of the converter is also available for railway applications.
