Operating information
Input Voltage
The input voltage range 36 to 75Vdc meets the requirements
of the European Telecom Standard ETS 300 132-2 for normal
input voltage range in —48 and —60 Vdc systems,
-40.5 to -57.0 V and —50.0 to -72 V respectively.
At input voltages exceeding 75 V, the power loss will be
higher than at normal input voltage and T
absolute max +100°C. The absolute maximum continuous
input voltage is 75Vdc.
Turn-off Input Voltage
The DC/DC converters monitor the input
voltage and will turn on and turn off at predetermined levels.
The minimum hysteresis between turn on and turn off input
voltage is 1V.
Remote Control (RC)
The maximum required sink current is 1 mA. When the RC pin
is left open, the voltage generated on the RC pin is
3.0 — 6.5 V.
The second option is “positive logic” remote control, which
can be ordered by adding the suffix “P” to the end of the part
number. The converter will turn on when the input voltage
is applied with the RC pin open. Turn off is achieved by
connecting the RC pin to the - In. To ensure safe turn off the
voltage difference between RC pin and the - In pin shall be
less than 1V. The converter will restart automatically when this
connection is opened.

DC/DC converters, Input 36-75 V, Output 30A/150W
The products are fitted with a
remote control function
referenced to the primary
negative input connection (- In),
with negative and positive logic
options available. The RC function
allows the converter to be turned
on/off by an external device like a
semiconductor or mechanical
switch.

Output Voltage Adjust (V
The DC/DC converters have a Output Voltage Adjust pin (V
This pin can be used to adjust the output voltage above or
below Output voltage initial setting.
When increasing the output voltage, the voltage at the output
pins (including any remote sense compensation ) must be
kept below the threshold of the over voltage protection, (OVP)
to prevent the converter from shutting down. At increased
output voltages the maximum power rating of the converter
remains the same, and the max output current must be
decreased correspondingly.
To increase the voltage the resistor should be connected
between the V
Output voltage adjust function is according to information
given under the Output section for the respective product.
To decrease the output voltage, the resistor should be
connected between the V
Remote Sense
The DC/DC converters have remote sense that can be used
to compensate for voltage drops between the output and the
point of load. The sense traces should be located close to the
PCB ground layer to reduce noise susceptibility. The remote
sense circuitry will compensate for up to 10% voltage drop
between output pins and the point of load.
If the remote sense is not needed +Sense should be
connected to +Out and -Sense should be connected to -Out.
