More Information

Overview Manuals Voltage Boundary Receiving Identity Parts Context Product Applications

Features:

  • Drive role: chopper control card within the Bulletin 1352C renewal-parts structure.
  • Configuration boundary: assigned to Series C GTO 575 V drive arrangements.
  • Spare identity: cross-referenced by part 504082 and Bulletin number 3500-CH7.
SAFT127 CHC belongs to the chopper-control path of the applicable Series C drive rather than the I/O, power-supply, or pulse-amplifier groups.

The 575 V assignment is the defining configuration boundary; the official parts table lists a separate chopper-control card for 460 V equipment.

The type designation, part number, Bulletin number, drive Series, and voltage class together form the most reliable receiving and maintenance identity record.

Apter Power supports document review, quotation, and procurement for the discontinued ABB SAFT127 CHC Chopper Control Card.

  • Series scope: select the card only for the Series C parts structure identified in the drive record.
  • Voltage class: the official assignment is the GTO 575 V configuration, which governs spare selection.
  • Adjacent card limit: the 460 V chopper-control entry is a different type and must not be treated as equivalent.
  • Drive evidence: use cabinet documentation and the installed card record to resolve any mixed-voltage spare history.
  • Type string: receive the board against the complete SAFT127 CHC product identity.
  • Part reference: part 504082 links the supplied board to the official renewal-parts entry.
  • Bulletin reference: 3500-CH7 provides the corresponding Bulletin number for purchasing records.
  • Record consistency: the model, two references, Series, and voltage class should resolve to one spare-card record.
  • Circuit-card group: the official renewal-parts table places this item among drive circuit cards.
  • Functional separation: chopper control remains distinct from braking-chopper, power-supply, I/O, and pulse-amplifier entries.
  • Series notation: the row is limited to Series C instead of the broader ABC notation used by some neighboring cards.
  • Maintenance value: preserving the original table references reduces ambiguity when older cabinet drawings use abbreviated identifiers.
  • Bulletin 1352C maintenance: renewal-part identification for supported Series C drive cabinets.
  • GTO 575 V service: chopper-control replacement where the installed configuration matches the official voltage-class assignment.
  • Legacy spare procurement: cross-reference control for orders using model, part, or Bulletin identifiers.
  • Receiving inspection: reconciliation of the delivered board with the installed drive and historical parts record.
Description
SAFT127 CHC is the chopper control card assigned to GTO 575 V configurations in the Bulletin 1352C Series C renewal-parts structure. Its role and voltage-class boundary make it a configuration-specific drive spare rather than a general control card.

For maintenance teams, SAFT127 CHC must remain separate from the 460 V card listed in the same official table. This distinction prevents a visually similar chopper-control board from being selected across incompatible voltage classes.

Ordering SAFT127 CHC should retain the cross-reference to part 504082 and Bulletin number 3500-CH7. Matching the installed drive series, GTO configuration and historical spare record gives procurement and receiving teams a consistent identity chain for this discontinued board.

Technical notes
Voltage-class substitution is the main risk with SAFT127 CHC. The official Series C parts table assigns it to GTO 575 V configurations, while the adjacent 460 V chopper-control entry uses a different card. Do not treat the two as equivalent; stop replacement if drive voltage, Series, or card identity cannot be reconciled.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
A plant has a Bulletin 1352C Series C drive at 575 V; when is SAFT127 CHC the correct spare?
Select it only when the installed configuration is GTO 575 V and the spare record also resolves to part 504082 or Bulletin 3500-CH7. Stop if the drive voltage or Series differs.
Can maintenance use SAFT127 CHC when the removed chopper-control card belongs to a 460 V drive?
No. The official parts table assigns the 460 V arrangement to a different card, so a cross-voltage substitution must not proceed.
How should receiving inspect SAFT127 CHC when the shipment paperwork shows only part 504082?
Reconcile part 504082 with the full model, Bulletin 3500-CH7, Series C, and the 575 V GTO equipment record before accepting the board.
The bill of materials lists 3500-CH7 but not a type designation; what should procurement order for SAFT127 CHC?
Use the official mapping from 3500-CH7 to part 504082 and the complete SAFT127 CHC identity, then confirm the installed Series C voltage configuration.
If SAFT127 CHC is found in mixed legacy spares, how can a technician avoid assigning it to the wrong cabinet?
Keep the board with its model and reference labels, then match the destination cabinet by Series and 575 V GTO configuration before release to maintenance.
What should maintenance record after assigning SAFT127 CHC to a Bulletin 1352C drive?
Record the full model, part 504082, Bulletin 3500-CH7, Series C, 575 V GTO match, board condition, and destination cabinet.
