We recommend integrating autotransformer the field power converter's supply circuit adjust the input volt age the field voltage and for reducing the voltage ripple in the field circuit single-phase operation.500V/1-ph +10% single-phase three-phase 24 DC external fuse L3 line choke 3-phase operation use: ND401 A DCF803-0035 0..8 Uvor 1.500V/1-ph +10% 115 230 V DCS800-S0x-xxxx-05 see table on page 7 200V.3 520 A • Minimum field current monitor • Integrated external field power converter completely separate switchgear cubicle • single-phase 3-phase model • Controlled serial communication via DSLLink All field converters are controlled the armature converter via serial interface (SDCS-DSL-4board)..9 100% TOL tolerance line voltage % Uv Line voltage UA= Field voltage Recommendation (single-phase operation): UA= 0.3. • Construction and components have been designed for insulation voltage of 600 AC.. This interface serves to parameterize, control and diagnose the field converter and thus provides exact control.
