Features:
- Fits the 15 A SIMOREG DC-MASTER converter class.
- Supplies a field circuit rated at 3 A DC.
- Uses a two-pass primary-conductor arrangement with equal R1/R2 values.
C98043-A7010-L1 is the lower-current member of the A7010 field-supply pair and is selected by the converter’s 15 A armature rating.
Its equal sensing-resistor values and doubled primary path establish the L1 current-measurement arrangement.
Field input, controlled bridge, and DC field output are separated into clearly named connection points for tracing during integration.
The Siemens C98043-A7010-L1 Field Supply Power Section may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Supply, Switching, and Field Output
- Input Pair: 3U1 and 3W1 supply the bridge.
- Control Devices: V7 and V8 form the thyristor pair.
- Output Pair: 3D and 3C connect to the DC field circuit.
- Rated Field: The L1 bridge is rated at 3 A DC.
Two-Pass Measurement Path
- Armature Class: The L1 arrangement belongs to 15 A converters.
- Primary Path: The primary conductor is fed through twice.
- R1: The R1 element is 0R1.
- R2: The R2 element is also 0R1.
Gate and Cathode Marking
- Gate Color: Gate leads are identified in yellow.
- Cathode Color: Cathode leads are identified in red.
- Lead Type: Betatherm 145 cable is specified for gating.
- Lead Size: The stated cross-section is 1 mm².
Restoring Field-Current Zero
- Trigger: Repeat the adjustment after the field board is replaced.
- Parameter: Use P051 = 22 for the internal offset routine.
- Purpose: The routine sets the zero point of field-current sensing.
- Power State: Carry out physical replacement only with supplies isolated.
