The universal digital metering system of the series AC-UNI, available in sizes 96*96 and 144 * 144, will used to measure the present values of a connected net. Following values will be acquired and calculated:

-     Currents L1, L2, L3
-     Voltages L1-N,L2-N, L3-N,L1-L2,
      L2-L3,L3-L1
-     Frequency
-     Cos j
-     kW, kVAr, KVA
-     ±kWh, ±kVAr

The current measurement will be done directly or for large current values with a current transformer (.../5A or .../1A) and the voltage measurement will be done directly or for large voltage values with a voltage transformer (.../110V).

-       16 Bit micro controller
-       3 Inputs current
-       3 Inputs voltage
-       3 free selectable digital displays
-       2 Relay outputs

with following options:
-   4 Digital inputs
-       0(4)-20mA analog output
-       RS 485 communication port
-       10 additional relays
-    Load forecast with load shedding using
    relay within 15min. period
