Galvanic Isolation - T90, A92, F11, F90 - ABB DCS880 Manual

Galvanic isolation - T90, A92, F11, F90

The Galvanic isolation is an option for converters size H4T, H6 ... H8 and rated voltages ≤ 1000 V.
It is used to replace the high-ohmic voltage measurement and gives the advantage of a total isolation
between power part and drive electronics.
The transformer T90 and the DC-DC transducer A92 are located outside the converter module. The
internal AC and DC voltage measurement channels are removed and connected to T90 and A92.
