The SNV018EC card is a DC current measurement & monitor card with an
additional sense input. It is designed to be used in systems where the current
monitoring is necessary, for example it can be used in photovoltaic parks with
central inverters in order to monitor string currents.
The SNV018EC card is manufactured in four versions of 8, 12, 16 or 24 channels of
DC current measurement.
The SNV018EC offers the following:
8, 12, 16, 24 isolated channels of dc current measurement
(common low side)
0-13.5A measurement ranges (other ranges are available on demand)
Very Low Sensing resistance on measurement channels: 10mΩ
Measurement channels voltage up to 1000Vdc
1kHz sampling per channel
1 contact input
Board temperature measurement
On board long time averaging and integrations
Communication using MODBUS over RS485
Up to 127 cards connected in series
Board power consumption < 1.5W
Operating temperatures : -20°C to +60°C
CE: EMC: EN61326-1 and Safety: EN61010-1
