FUNCTIONAL DESCRIPTION
4.1
GENERAL
PRX is a complete rectifier with integrated monitoring.
Most functions are handled by the monitoring unit and are described in the
Manual for monitoring
unit PCM2
. Only the functions that feature at a general rectifier level are described here.
4.2
FRONT PANEL
The front panel includes the operator panel, mains breaker and voltmeter terminal.
The operator panel is the unit used as the user interface. It is fitted with a display, keypad and
indicator lamp for alarm.
The mains breaker handles the mains feed to the rectifier modules.
The voltmeter terminal has short-circuit protection for safe measurement of the battery voltage and
is designed for standard 4 mm banana plugs.
4.3
RECTIFIER MODULES
The rectifier modules are of the “plug-in” type and can in principle be replaced during operation.
There is room for up to two parallel modules. The rectifier modules can be accessed by folding out
the front panel of the equipment.
There are three indicator lamps on the front of the module. These are only visible with the front
panel folded out:

I/O UNIT
The I/O unit contains an adapter for the external connections required for the monitoring unit. It is
fitted directly on the back plate together with the terminal blocks for AC input and DC output.
The I/O unit is also available in a more basic design where certain functions and connections are
not included. This design is referred to here as “simplified version”.
