Operating Information
Input Voltage
The input voltage range 36…75Vdc meets the requirements
of the European Telecom Standard ETS 300 132-2 for normal
input voltage range in –48V and –60V DC systems, -40.5…-
57.0V and –50.0…-72V respectively. At input voltages
exceeding 75V, the power loss will be higher than at normal
input voltage and TPcb must be limited to absolute max
+125°C. The absolute maximum continuous input voltage
is 80Vdc.
Turn-Off Input Voltage
The PKJ 4000E Series 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 where the turn on input voltage is the highest.
Output Voltage Adjust (Vadj)
All PKJ 4000E Series DC/DC converters have an Output Volt-
age 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 ov-
ervoltage trip point, to prevent the converter from shut down.
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 PKJ 4000E Series DC/DC
converters have a remote control
function referenced to the primary side
(- 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 needed
maximum sink current is 1mA. When the RC pin is left
open, the voltage generated on the RC pin is 3.5-6.0V. The
maximum allowable leakage current of the switch is 50A.
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 1V. To turn off
the converter the RC pin should be left open, or connected to a
voltage higher than 4V 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 1V. The converter will restart automatically when this
connection is opened.
All PKJ 4000E Series 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.
