PPV10 is a programmable multirange converter / isolation amplifier with 1- and 3-phase voltage input, one current input and current, voltage, pulse or relay outputs.
The unit has a number of programmable input functions:
Monitoring of phase angle or power consumption on single phase AC or DC loads.
Monitoring of phase angle or power consumption on symmetrical 3-phase loads.
The unit is supplied with 2 voltage range and 3 current range inputs, in order to achieve the highest possible accuracy.
The unit can operate between 20 and 750 V input voltage and 150 mA to 6 A input current. If the metering current exceeds 6 A, you can use an external current transformer, and in this way it is also possible to monitor very big loads.
The supply voltage for the unit is separated from the metering signal, this is particularly interesting, if there is a big variation of the metering voltages.
You can select between 2 different output configurations:
Type A is supplied with analogue current output, programmable between 0 and 20 mA and analogue voltage output, programmable between -10 and +10 V.
Type B has the same outputs as type A, but in addition it is also supplied with pulse output, programmable to a maximum frequency of 10 kHz.
The unit is supplied with 2 trimming potentiometers, which can be used to fine-adjust the metering range, if the unit is used with analogue outputs, or to adjust the set-point if the unit has relay outputs. In either case the potentiometers can be disabled and fixed values selected, if adjustment is not required.
