Temperature compensation models (ex. PAP3200/24T)
The temperature compensation wire enables the charger to adjust the output voltage in accordance with the
battery voltage and changes in temperature. The temperature compensation wire and battery voltage sense
cables are connected to connector J101 terminals 11…14 (see above). Connect the cable to the battery as shown
in the illustration. The temperature sensor is either glued 10 cm below the top edge of the battery, or fixed to the
cable tag connected to the minus terminal of the battery.
Optional master–slave connection
Using a master power supply together with a slave unit.
The master unit can be either a trimmer adjustable model (e.g. PAP3200/24) or an analog controllable model (e.g.
PAP3200/24AI). The slave unit is a separate unit without any adjustment possibilities, e.g. type PAP3200/24S or
PAP3200/24SH, which has an alarm relay output.
If more current or a higher voltage is needed, the adjustable master power supply can be connected in parallel or
in series, via the digital bus, with the slave unit, which follows the master unit but has no adjustment possibilities
by itself. Dependent on the connection, the maximum output current, or the voltage is doubled, while both power
supplies are simultaneous adjusted using the multi turn potentiometers, or external analog control. An unlimited
amount of slaves can be connected to a master unit. The power supply’s output terminals and the communication
bus terminals are isolated, so that the outputs can be connected in series for obtaining a higher voltage.
Serial bus connection
The bus cable is connected from the master unit (J101) to
the slave unit (J101). The first unit, or master unit has
potentiometers for voltage and current adjustment. An
erroneous connection of the bus cable does not cause any
damages, but causes the slave unit to not follow the
commands sent from the master unit.
J101 has the following terminal configuration:
Pin 7 of the master unit is connected to pin 9 of the slave
unit. Pin 6 of the master unit is connected to pin 8 of the
slave unit.
