More Information

Overview Manuals Identity Retrofit Service Applications

Features:

  • Exact board label: Identified as SNAT 633 PAC Rev. A.
  • Traceable code: The board code is 61049444.
  • Pulse-amplifier role: Belongs to the SNAT 63X PAC family used with ACV700 GTO hardware.
SNAT633PAC provides a model-, code- and revision-specific identity for ACV700 pulse-amplifier service.

Revision control matters when ACV700 GTO inverters remain in service beside staged ACS880 retrofit sections.

The full label should therefore be captured before quotation, removal or installation work begins.

Apter Power can assist with quotation and documentation support for the ABB SNAT633PAC Pulse Amplifier Board.

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
  • Type marking: The manufacturer label reads SNAT 633 PAC.
  • Board code: Use code 61049444 for the exact board identity.
  • Revision: The identified unit is Rev. A.
  • Board family: The board belongs to the SNAT 63X PAC pulse-amplifier family.
  • Retained equipment: Identify every ACV700 GTO inverter that will remain during a staged retrofit.
  • Revision rule: ABB requires the retained SNAT 63X PAC boards to be the newest revision.
  • Interference risk: An outdated revision can affect retained ACV700 inverters near ACS880 sections.
  • Project boundary: Do not infer newest-revision status from the SNAT 63X family name alone.
  • Before removal: Capture the board code, revision and connector orientation.
  • Before quotation: Match SNAT 633 PAC, code 61049444 and the installed ACV700 context.
  • Before installation: Resolve any difference between the offered and installed revision.
  • Before power: Follow the approved ACV700 isolation and commissioning procedure.
  • ACV700 maintenance: Supports exact-board service in GTO inverter hardware.
  • Staged modernization: Provides the revision checkpoint for retained ACV700 sections.
  • Workshop evaluation: Links the board under test to code 61049444 and Rev. A.
  • Spare planning: Allows revision-controlled stocking for a defined legacy inverter population.
Description
SNAT633PAC is the ABB SNAT 633 PAC Rev. A pulse-amplifier board identified by code 61049444 for ACV700 GTO inverter hardware.

SNAT633PAC belongs to the SNAT 63X PAC family, where board revision becomes an engineering control during staged ACS880 retrofit work because retained ACV700 inverters can be affected by interference.

SNAT633PAC gives maintenance and procurement teams a traceable code-and-revision identity, allowing the installed pulse-amplifier hardware to be reviewed without treating visually similar SNAT 63X PAC boards as interchangeable.

Technical notes
SNAT633PAC is a Rev. A SNAT 63X PAC pulse-amplifier board with code 61049444 for ACV700 GTO hardware. During a staged ACS880 retrofit, ABB requires retained ACV700 pulse-amplifier boards to be at the newest revision to reduce interference risk. Stop if the installed revision cannot be established.

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.
Can a staged retrofit reuse SNAT633PAC Rev. A without checking the other retained inverters?
No. ABB requires the retained SNAT 63X PAC boards to be at the newest revision, so review every ACV700 GTO section before introducing ACS880 hardware.
What should a maintenance engineer do when SNAT633PAC is labelled correctly but code 61049444 is missing?
Stop the replacement. The type, code and revision form the traceable identity, and a partial label cannot establish the exact board being fitted.
Can SNAT633PAC be substituted with another SNAT 63X PAC board that has the same connector layout?
Not from appearance alone. Confirm the exact code, revision and installed ACV700 configuration before accepting a family-level alternative.
Why might an ACV700 inverter become unstable after nearby equipment is modernized while SNAT633PAC remains installed?
Revision-related interference is a known staged-retrofit concern. Compare the retained pulse-amplifier revisions with ABB's newest-revision requirement before investigating unrelated replacements.
What information should an outage RFQ include for SNAT633PAC?
Provide code 61049444, Rev. A, the complete ACV700 inverter designation, the number of retained GTO sections and whether modernization is staged.
When should commissioning stop after fitting SNAT633PAC?
Stop before energising if the board revision, connector map or installed ACV700 identity differs from the recorded configuration; resolve the mismatch under the approved service procedure.
