Interface port on each rectifier. The rectifiers with the higher voltage output will
automatically adjust their output voltage down so that they each take a uniform share of
the load.
The rectifiers connected in parallel must all be of the same brand and voltage rating.
Different power ratings can be combined, a 300W model may be connected in parallel
with a 600W model (e.g. a 324 with a 624).
2.13
External Shutdown
The rectifier can be remotely forced to shutdown by applying a positive 10-12V signal to
the rectifier load share pin of the Monitor connector. (With respect to –ve battery/load
common)
2.14
Alarm & Control Interface
The monitor connection allows remote monitoring of the rectifier. The monitor
connection is a RJ45 socket. The pinout of the socket is as follows:
Table 3: Pin descriptions
Pin #
Description
Pin 1
Load Share signal (0-5V), external shutdown (10-12V in)
Pin 2
LVD Synch signal
Pin 3
Temp Comp Probe/Output Voltage Control
Pin 4
Rectifier Failed Signal – Pulls to ground via 4k7 resistor
Pin 5
-ve for Temp Comp Probe (signal Gnd)
Pin 6
Rectifier “Off Normal” alarm (open collector output)
Pin 7
+V Battery Out (max 250mA)
Pin 8
Mains fail (open collector output) (off = mains present)
2.15
Internal Alarm Card (Optional)
The internal alarm card may be fitted to a rectifier. The alarm card provides voltage free
relay contacts in the event of:
•
Mains failure
•
Rectifier failure
•
Rectifier Off Normal (over temperature, over voltage, current limit)
•
High voltage output
•
Low voltage output

Pin 1 is the left most pin, when facing
the socket with the pins on the bottom.
