Operating information
Input Voltage
Output Voltage Adjust (Vadj)
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 Tref must be limited to absolute max
+110°C. The absolute maximum continuous input voltage is
80Vdc.
Turn-off Input Voltage
The PKM 4000CSeries 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 1 V.
All PKM 4000CSeries DC/DC converters have an Output
Voltage adjust pin (Vadj). 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 offset) must be kept below
the maximum output adjust range. Also note that at increased
output voltages the maximum power rating of the converter
remains the same, and the output current capability will
decrease correspondingly.
To decrease the output voltage the resistor should be
connected between Vadj pin and —Sense pin. To increase the
voltage the resistor should be connected between Vadj pin
and +Sense pin. The resistor value of the Output voltage
adjust function is according to information given under the
output section.
Remote Control (RC)
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. The RC pin has an internal
pull up resistor to + In.
The maximum required sink current is 1 mA. When the RC pin
is left open, the voltage generated on the RC pin is 3.5 — 6.0
V.
Remote Sense
The standard converter is provided with “negative logic”
remote control and the converter will be off until the RC pin is
connected to the - In. To turn on the converter the voltage
between RC pin and - In should be less than 1 V. To turn off
the converter the RC pin should be left open, or connected to
a voltage higher than 2 V referenced to - In. In situations
where it is desired to have the converter to power up
automatically without the need for control signals or a switch,
the RC pin can be wired directly to - In.
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 0.8 V. The converter will restart automatically when
this connection is opened.
All PKM 4000CSeries DC/DC converters have remote sense
that can be used to compensate for moderate amounts of
resistance in the distribution system and allow for voltage
regulation at the load or other selected point. The remote
sense lines will carry very little current and do not need a large
cross sectional area. However, the sense lines on the Pcb
should be located close to a ground trace or ground plane. In
a discrete wiring situation, the use of twisted pair wires or
other technique to reduce noise susceptibility is highly
recommended. The remote sense circuitry will compensate
for up to 10% voltage drop between the sense voltage and
the voltage at the output pins. The output voltage and the
remote sense voltage offset must be less than the minimum
over voltage trip point. If the remote sense is not needed the —
Sense should be connected to —Out and +Sense should be
connected to +Out.
