VITAC 200 provides measurement and ATS control functions, and major parameters related to ATS
control can be modified using engineering software.
The single-phase voltage and frequency of the commercial and emergency power can be measured.
The following table shows the measurement range and precision.
VITAC 200 supports the W-Type and WN-Type ATS of VITZRO and various ATS of other suppliers.
If VITAC 200 is used with the 3Position ATS (as the WN-Type ATS of VITZRO), use the same wiring
