VOLTAGE:
Up to 1000 V DC / 600 V AC fully configurable via USB.
CURRENT:
Up to 10 A AC/DC (more by using external CT).
CURRENT:
0...20mA programmable, max load 600 ohm.
VOLTAGE:
0...10 V programmable, min load resistence 2k ohm.
RS485 MODBUS:
Bus connection on the basis of the module or terminal, dip-switch for setting address and baudrate.
CONTACT OUTPUT:
Optomos contact, programmable N.O. alarm contact by free interface software FACILE QA-POWER, retransmission or storage pulse (not volatile memory).
Photovoltaic:
Parallel String Voltage monitoring.
Energy Management:
Direct comunication via RS485 Mobus to all Master Modbus devices.
High Voltage AC/DC converter.
High Current AC/DC converter using external CT.
Local and Remote monitoring at the same time.
Datalogger on pen drive stick memory with .csv file (direct import to Excel).
TYPE OF MEASURE:
allows the selection of the measure RMS or DC only to define the sign, positive or negative, of reading.
REPORT OF TRANSFORMATION:
in case you would use the CT and / or VT, you can define the transformation ratio for the current input and voltage input, the default ratio is 1:1.
FILTER:
allows you to insert a filter on reading in order to get more speed in responding (value 1) or a more stable and accurate measurement (value 5 ), by default the value is set to 2. You can choose between intermediate values already set or manually enter the desired filter by choosing the CUSTOM option from the menu, in this case, you can set the following parameters: filtering in DC, filtering in AC (default value 5), Frequency measurament on Current channel.
MIN CURRENT THRESHOLD
(mA): Allow you to set the minimum current value (Cut off). Under this value the device measure Zero.
MIN POWER THRESHOLD (W):
Allow you to set the minimum power value (Cut off). Under this value the device measure Zero.
