Programmable converter type PPV10
Programmable converter type PPV10
| 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. If you want, you can order the unit with specified 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. |
All parameters in the converter are programmable within the specified limitations (min. and max. input and output levels), giving the following possibilities: | ||
| Basic converter, (0 to defined input range and standard output range, 0-20 mA, 4-20 mA or 0-10 V). |  |
||
| Converter with input and/or output offset, e.g. 200 to 800W input and 8 to 15 mA output. |  |
||
| Bidirectional input range (phase angle), e.g. -50 to +40 deg. |  |
||
| Bidirectional output range (only voltage output), e.g. -10 to +10 V. |  |
||
| Inverted function with or without offset, f.inst 300 to 200 W input and 4 to 20 mA output. |  |
