Function - Knick VariTrans P 2900 P2 Série Mode D'emploi

Function

The input signal is converted into a pulse-width modulated signal
and is transferred to the primary side of a transformer. On the second-
ary side the pulse-width signal is converted back into an impressed
current or an impressed voltage.
3-port isolation with protective separation up to 600 V AC/DC
according to EN 61140 ensures optimum protection of personnel and
equipment as well as unaltered transmission of measuring signals.
Easy scalability supports customized solutions; optimally adapted to
the respective application, up to 192 tailor-made signal combinations
can be implemented in one device.
