Remote Sense
All PKJ series DC/DC power modules 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 a PCB should be located close to a ground trace or
ground plane. In a discrete wiring situation, the usage of twisted pair
wires or other technique for reducing noise susceptibility is
recommended.
The power module will compensate for up to 0.5 V voltage drop
between the sense voltage and the voltage at the power module
output pins. The output voltage and the remote sense voltage
offset must be less than the minimum overvoltage trip point.
If the remote sense is not needed the -Sen should be connected
to -Out and +Sen should be connected to +Out.
Current Limiting
General Characteristics
All PKJ series DC/DC power modules include current limiting circuitry
that makes them able to withstand continuous overloads or short circuit
conditions on the output. The output voltage will decrease toward zero
for heavy overloads (see product code characteristics).
The power module will resume normal operation after removal of the
overload. The load distribution system should be designed to carry
the maximum short circuit output current specified (see applicable
code typical characteristics).
Over Voltage Protection (OVP)
All PKJ DC/DC power modules have latching output overvoltage
protection. In the event of an overvoltage condition, the power mod-
ule will shut down. The power module can be restarted by cycling
the input voltage.
Turn-off Input Voltage (VIoff)
The power module monitors the input voltage and will turn on and
turn off at predetermined levels.
Operating Information
Input Voltage
The input voltage range 36...72V meets the requirements in the
European Telecom Standard ETS 300 132-2 for normal input voltage
range in -48 V and -60 V DC power systems, -40.5...-57.0 V and
-50.0...-72.0 V respectively. At input voltages exceeding 72 V,
(abnormal voltage), the power loss will be higher than at normal
input voltage and TC must be limited to absolute max +90 C. The
absolute max continuous input voltage is 75 V DC. Output charac-
teristics will be marginally affected at input voltages exceeding 72 V.
Remote Control (RC)
The RC pin can be wired directly to -In, to allow the module to
power up automatically without the need for control signals.
A mechanical switch or an open collector transistor or FET can be
used to drive the RC inputs. The device must be capable of sinking
up to 1mA at a low level voltage of 1.0V, maximum of 15 V dc, for
the primary RC.

Output Voltage Adjust (Trim)
Voltage Trimming
All PKJ series DC/DC power modules have an Output Voltage
Adjust pin. This pin can be used to adjust the output voltage
above or below VOi. When increasing the output voltage, the
voltage at the output pins (including any remote sensing offset)
must be kept below the overvoltage trip point. Also note that
at elevated output voltages the maximum power rating of the
module remains the same, and the output current capability will
decrease correspondingly.
To decrease VO connect Radj from - SEN to Trim
To increase VO connect Radj from + SEN to Trim
Decrease : Radj = (21*VO-2.5)/(2.5-VO) k ohm
Increase : Radj = (9.7*VO+1.225)/(0.49*VO-1.225) k ohm
Decrease : Radj = (11VO-3.3)/(3.3-VO) k ohm
Increase : Radj = 15.94*(VO+0.207)/(VO-3.3) k ohm
Decrease : Radj = (11VO-4.965)/(4.965-VO) k ohm
Increase : Radj = (7.286*VO+1.225)/(0.2467*VO-1.225) k ohm
