Features:
- Supports the 30 A SIMOREG DC-MASTER converter class.
- Provides a 5 A rated DC field-current path.
- Connects the field bridge through 3U1/3W1 and 3D/3C terminals.
C98043-A7010-L2 separates the field-supply function from the converter control electronics while remaining part of the low-current power section.
The L2 coding defines the 30 A armature class, 5 A field rating, and the lower R2 resistance used by this arrangement.
Both single-quadrant and four-quadrant connection drawings place the module in the field and power-section wiring path.
The Siemens C98043-A7010-L2 Field Supply Power Section may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Bridge Components and Sensing
- Bridge Devices: V7 and V8 form the controlled field bridge.
- Sensing Network: R1 is 0R1 and R2 is 0R05.
- Field Rating: The DC field-current rating is 5 A.
- Gate Leads: Betatherm 145 conductors are specified at 1 mm².
From AC Supply to DC Field
- AC Entry: Field supply enters through 3U1 and 3W1.
- DC Exit: Field output is presented at 3D and 3C.
- Connector Set: XF1 and XF2 group the field-bridge connections.
- Current Class: The L2 path is assigned to 30 A converters.
Operating-Quadrant Context
- 1Q Drawing: The module appears in the 30 A single-quadrant connection plan.
- 4Q Drawing: The same field section is shown for 15–30 A four-quadrant converters.
- Primary Route: The L2 primary conductor is fed through once.
- Power Context: Armature and field paths remain separately identified in the converter wiring.
Safe Board Change Sequence
- Isolation: Remove power before the PCB is inserted or removed.
- Personnel: Replacement is restricted to qualified personnel.
- ESD: Discharge static electricity before touching the board.
- Offset: Run P051 = 22 after replacement to reset the field-current zero point.
