Features:

  • Legacy CENTUM XL cabinet power-supply module
  • Dedicated supply-position interface for installed rack electronics
  • Serviceable power-path component for planned control-system maintenance
Integration focus: Confirm the complete suffix, cabinet position, mating connector and upstream feed against the installed drawings.

Engineering consequence: A downstream short or missing upstream feed can imitate a failed module, so the full power path must be isolated methodically.

Commissioning focus: Energize under the approved sequence and confirm stable cabinet rails, normal indicators and controller startup before reconnecting process loads.

Apter Power supports the Yokogawa PS35*A CENTUM XL Power Supply Module with exact-model quotation and installed-cabinet checks.

Important Notice: Use the complete model, suffix and installed-system documentation before service or installation.

  • Verify the upstream cabinet feed and protective devices before disconnecting the module.
  • Check downstream rails for a short or abnormal load before fitting the supply; otherwise a new module may trip immediately.
  • Confirm that the cabinet grounding and backplane connections follow the installed CENTUM XL drawing.
  • Inspect the mating connector, card guides and retention hardware for heat damage or deformation.
  • Seat the module only in the documented supply position and keep adjacent airflow paths unobstructed.
  • Apply power with downstream loads controlled so abnormal current can be isolated safely.
  • If cabinet power is absent, separate upstream feed loss, module output loss and downstream short-circuit symptoms.
  • Compare indicator state with measured input and output conditions using the site electrical procedure.
  • Repeated trips after startup require investigation of connected loads and cooling, not repeated module substitution.
  • Installed CENTUM XL cabinets that retain the documented PS35*A supply position.
  • Planned power-path maintenance in chemical, refinery and utility process-control systems.
  • Life-extension projects where the original cabinet and backplane architecture remain in service.
Description
Yokogawa PS35*A is a legacy CENTUM XL cabinet power-supply module for the assigned supply position in an installed control-system hardware set.

Within the cabinet power path, PS35*A energizes the rack electronics rather than processing field signals; the upstream feed, mating connector, backplane condition and downstream load therefore influence whether the supply can start and remain stable.

For a planned outage, PS35*A lets maintenance teams restore the original power architecture while retaining the established backplane and control modules, provided the complete suffix and site electrical limits match the installed cabinet.

Technical notes
PS35*A serves the cabinet power path in an installed CENTUM XL hardware set rather than processing field I/O. A missing upstream feed or a downstream short can reproduce a supply fault, so the power path should be separated before the module is judged. This protects the module and shortens cabinet recovery time.

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.
Why can a CENTUM XL cabinet remain dead after PS35*A is installed?
Check the upstream feed, protective device, mating connector and downstream rail for a short. A correctly seated supply cannot start the cabinet if another part of the power path is open or overloaded.
What should be measured before energizing PS35*A?
Use the site procedure to verify the incoming supply, protective earth and absence of an abnormal low-resistance condition on the downstream cabinet rails.
Why might PS35*A trip again immediately after startup?
A downstream module or backplane fault can overload the supply. Isolate loads in the documented sequence rather than repeatedly energizing the same fault.
Can PS35*A be placed in any open CENTUM XL slot?
No. It belongs in the cabinet position defined for that supply path, with the correct mating connector, backplane relationship and airflow.
What should be checked if PS35*A becomes unusually hot?
Inspect cabinet ventilation, connector resistance, sustained load and surrounding heat sources. Discoloration or odor at the connector requires the cabinet to remain de-energized for inspection.
How should PS35*A be validated after service?
Confirm stable cabinet power, normal module and controller indications, clean startup diagnostics and reliable operation of the connected rack electronics before restoring the process.
