Artificial star adapter
G068: Artificial Star Adapter (Option, to be ordered separately)
The artificial star adapter creates an artificial star point to measure 3 phase signals
Maximum input voltage
1000 V DC (707 V RMS) between each of the phases
Inputs
3; 4 mm safety banana plugs
Outputs
6; 4 mm safety banana pins; plugs straight into GN610/GN611/GN610B/GN611B cards
Artificial star N
Reference plug only. Not to be used as input
Safety
Compliant with IEC61010
-
1 600 V RMS CAT II
Application use
The 3 phase signals L1, L2 and L3 can be connected with inputs L1, L2, L3 of the artificial
star adapter. The connection N* is the voltage present on the artificial “star point”.
