PPV10, 1-and 3-phase power inputs - COMADAN - #1

All parameters in the converter are programmable within the specified limitations (min. and max. input and output levels), giving the following possibilities:

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, ifthe unit is used with analogue outputs. In either case the po­tentiometers can be disabled, if adjustment is not re­quired.

If you want, you can order the unit with specific metering ranges, or you can program it yourself, by means of the C-mac programming software for PC and a small inter­face to connect between the PC and the module.
