Solving the Discontinued Hardware Crisis

Q: How are RFQ terms confirmed?
A: Quantity, required condition, documentation needs, destination and sourcing route are confirmed during RFQ review before quotation.

The KJ1501X1-BC3 power supply sits at the foundation of DeltaV controller node operation. Without a functioning power supply, the entire I/O subsystem it feeds goes dark. In a redundant architecture, a failed primary unit forces the system into a degraded single-point-of-failure state — one more fault away from an unplanned shutdown. In a non-redundant installation, failure means immediate process trip.

Emerson ceased active production of this module as the DeltaV platform evolved toward newer hardware generations. End users who did not stockpile spares during the transition window now face a secondary market that is thinning rapidly. Each year, more units are consumed from decommissioned plants and not replenished. The window to source a verified unit at a rational price is narrowing.

Condition & Reliability Assurance

DriveKNMS applies a 5-step qualification process to all obsolete power supply modules before they are offered for sale:

Key Features for System Maintenance

• Drop-in replacement: The KJ1501X1-BC3 installs directly into the existing DeltaV carrier without hardware modification.
• No reprogramming required: Power supply modules in the DeltaV architecture do not carry application logic. Replacement does not require DCS engineering intervention or control loop reconfiguration.
• Avoids engineering reconstruction costs: Substituting a like-for-like spare eliminates the need for system re-validation, loop testing, and regulatory re-certification that a platform migration would trigger — costs that routinely reach six figures in regulated industries.
• Maintains system certification integrity: In FDA-regulated or SIL-rated installations, replacing a module with a certified equivalent preserves the existing validation status. A platform change does not.

Q: How is condition confirmed before quotation?
A: Available condition, photos, test records and documentation are checked according to the requested model and sourcing channel before a formal RFQ response.

Q: Can you support multi-unit or repeat RFQ requests?
A: Yes. Send the model list, target quantity and destination so DRIVEKNMS can review sourcing options and quote the requirement as a project RFQ.

Q: Can this unit be used in a redundant power supply configuration?
A: Compatibility with redundant configurations depends on your specific DeltaV carrier and system revision. Confirm your carrier model and DeltaV system version with our technical team before ordering.
