AutoPilot Digital Nano Plus Power Module | STK0123

AutoPilot STK0123 was an internal replacement power module used in compatible Pool Pilot Digital Nano Plus salt chlorine generator power centers. The module supplied and regulated electrical power used by the controller and salt cell during chlorine production.

This component is now discontinued. AutoPilot's current replacement path is not another STK0123 internal module. The complete legacy power center should instead be replaced with the AutoPilot Pool Pilot Evolve PCR0003A power center.

Product Information

  • Legacy OEM component: STK0123 was designed for compatible AutoPilot Pool Pilot Digital Nano Plus salt chlorine generator power centers.
  • Internal electrical part: This was not a complete salt chlorine generator, complete control box, salt cell or plumbing manifold.
  • No longer supplied: The original STK0123 internal power module has been discontinued and cannot be ordered through Aqua Terra Backyard.
  • Complete power-center upgrade required: Customers should replace the legacy control box with the current AutoPilot PCR0003A Evolve power center.
  • Existing equipment inspection: The salt cell, cell cord, tri-sensor and manifold should be inspected before connecting the replacement power center.
  • Professional electrical installation: Incoming voltage, grounding, bonding and field wiring must be verified before installation.

AutoPilot Pool Pilot Evolve Power Center | PCR0003A

The AutoPilot PCR0003A Evolve Power Center replaces the complete legacy Nano Plus power supply and controller. This is the appropriate path when the discontinued STK0123 power module has failed or is no longer serviceable.

The replacement power center manages chlorine output, powers the compatible salt cell and communicates with the connected AutoPilot manifold and tri-sensor system.

Important Replacement Clarification

PCR0003A Replaces the Complete Power Center

The PCR0003A is not another loose STK0123 circuit module. It replaces the legacy exterior power-center and controller assembly as a complete unit.

The replacement power center does not automatically replace every component in the salt chlorine generator system. The existing salt cell, manifold, tri-sensor, unions and plumbing may remain in use when they are compatible and in serviceable condition.

Before purchasing: Confirm the existing AutoPilot model, incoming voltage, salt-cell model, cell-cord condition, manifold and tri-sensor configuration.

Replacement and Installation Guidance

The discontinued STK0123 module should not be replaced with an unidentified aftermarket board or a visually similar electrical component. Replace the complete legacy power center with the approved PCR0003A Evolve power center.

  • Disconnect all electrical power before servicing the system
  • Confirm whether the installation is wired for 115V or 230V
  • Identify the existing Nano Plus power-center model
  • Inspect the salt cell for scale, wear or damaged plates
  • Inspect the cell cord for heat damage, corrosion or melting
  • Confirm the manifold has proper water flow
  • Inspect the tri-sensor and sensor cable
  • Correct plumbing leaks before installing the new power center
  • Follow current AutoPilot installation and wiring instructions
  • Use a qualified professional for electrical installation
A failed salt cell, damaged cord, poor flow, failed tri-sensor or incorrect salt level can produce symptoms that resemble a failed power center. Inspect the entire system before completing the replacement.

Frequently Asked Questions

Is AutoPilot STK0123 still available?

No. AutoPilot STK0123 has been discontinued and is no longer available through Aqua Terra Backyard. This listing remains online for identification and replacement guidance.

What was AutoPilot STK0123 used for?

STK0123 was an internal power module used in compatible AutoPilot Pool Pilot Digital Nano Plus salt chlorine generator power centers.

What replaces the discontinued STK0123 power module?

The recommended path is to replace the complete legacy Nano Plus power center with the AutoPilot Pool Pilot Evolve PCR0003A power center.

Is PCR0003A another internal circuit board?

No. PCR0003A is a complete Pool Pilot Evolve power center and controller. It replaces the legacy power-center assembly rather than only the discontinued internal STK0123 module.

Does PCR0003A replace a Digital Nano Plus power supply?

Yes. PCR0003A is the current complete power-center replacement path for compatible legacy AutoPilot Digital Nano Plus systems.

Is PCR0003A compatible with 115V and 230V installations?

PCR0003A can be field-wired for compatible 115V or 230V installations. The existing voltage and wiring must be verified before installation.

Does the PCR0003A replacement include a salt cell?

No. The replacement power center does not include a salt cell, manifold, tri-sensor, unions or plumbing unless the product listing specifically states that those components are included.

Can the existing AutoPilot salt cell still be used?

A compatible existing cell may remain in use when it is properly sized, electrically compatible and in serviceable condition. The cell and cord should be inspected before connecting the new power center.

Should I replace only the circuit board?

No current STK0123 internal replacement is offered through Aqua Terra Backyard. The proper replacement path is the complete PCR0003A Evolve power center.

What should be checked before replacing the power center?

Verify incoming voltage and inspect the salt cell, cell cord, manifold, tri-sensor, water flow and plumbing. These components can cause operating problems that may appear to be a failed power module.

Does the replacement require professional installation?

The replacement involves line-voltage pool equipment, grounding, bonding and field wiring. Installation should be completed according to AutoPilot instructions and applicable electrical codes by a qualified professional.

Replacing an AutoPilot Digital Nano Plus Power Center?

Confirm the existing control-box label, voltage, salt-cell model, manifold and tri-sensor before ordering the PCR0003A replacement.
