SeCtION 6 | rear Panel Connectors
The following output connectors have been provided (not shown).
1. load+ (positive), load- (negative) load connectors – for connecting to the D.C. load.
2. (positive), battery- (negative) battery connectors – for connecting external
battery for un-interrupted D.C. Power to the load.
Remote monitoring And Signalling
A provision has been made for remote signalling and monitoring of the following
operational conditions and parameters:
1. operational status of the 5 power supply modules (PSM)
2. failure condition of the cooling fan(s)
3. Availability of AC input power
4. output voltage measurement
5. output current measurement (voltage across an internal shunt with shunt ratio
of 50 mv / 100A or 0.5 Mv per amp)
Signalling of operational conditions as at serials 1, 2 and 3 above is opto coupled with
open collector, NPN transistor outputs. The collector and emitter of each opto coupled
transistor are accessible to the external user interface through the 25 pin d-sub connec-
tor. Each open collector, opto coupled NPN transistor can provide a maximum of
50 mA with a collector to emitter voltage of up to 35V. outputs for voltage and current
measurements at serials 4 & 5 above are direct analogue voltages. The pin out of the
25 pin d-sub connector providing the above signals for user interface is given below:
note: this signal is the voltage across an internal shunt at 0.5 mv per amp
(shunt ratio is 50 mv / 10A).
