YASKAWA CPS Series: Comprehensive Module Range and Technical Overview

The YASKAWA CPS Series power supply modules are a core infrastructure component deployed across global heavy industry installations, including petrochemical refineries, nuclear power auxiliary systems, steel manufacturing lines, and offshore platform control architectures. Designed to operate within YASKAWA's MEMOCON and Varispeed DCS/PLC backplane ecosystems, CPS Series units provide regulated DC bus power to CPU racks, I/O expansion racks, and communication adapter assemblies. Their wide input voltage tolerance and built-in overcurrent protection make them a preferred choice for facilities requiring continuous 24/7 uptime with minimal scheduled maintenance windows. The CPS-150F specifically delivers 150W of regulated output power and remains one of the most widely installed rack power supplies across legacy YASKAWA MP900, MP2000, and CP9200S controller platforms.

The Evolution of CPS Series Architecture

The CPS Series was introduced alongside YASKAWA's transition from relay-logic control panels to programmable rack-based automation in the late 1980s. Early units such as the CPS-100 and CPS-120 provided single-rail DC output with manual reset overcurrent protection, designed for the CP9200 and MEMOCON GL120 controller families. As YASKAWA expanded its MP-series motion controller platform through the 1990s and 2000s, the CPS Series was updated to support dual-rail outputs and hot-swap capability in select configurations.

The CPS-150F represents the mature generation of this architecture, incorporating soft-start circuitry, LED status indication, and improved EMI filtering compliant with IEC 61000-4 standards. Compatibility across backplane generations is a known integration challenge: CPS units are keyed to specific rack form factors and connector pinouts, and substitution between sub-series (e.g., CPS-100 vs. CPS-150F) requires verification of output voltage rails, connector type, and rack slot width. As the MP900 and CP9200S platforms have entered end-of-life status, sourcing CPS Series replacements through authorized aftermarket channels has become the primary maintenance strategy for installed base operators.

Sourcing Hard-to-Find & Obsolete CPS Series Parts

YASKAWA officially discontinued active production of several CPS Series models as the MP900 and CP9200S platforms reached end-of-life. For operators maintaining these systems, DriveKNMS maintains a dedicated inventory of new-surplus, refurbished, and tested-functional CPS Series units sourced from decommissioned plant equipment, authorized distributor overstock, and controlled warehouse environments.

DriveKNMS specializes in lifecycle extension support for YASKAWA legacy platforms. For obsolete CPS models, we provide: confirmed part number cross-referencing to verify compatibility before shipment; documented storage condition records for new-surplus units; and functional test reports for refurbished modules. Lead times for in-stock units are typically 1–3 business days with international shipping to all major industrial regions. For units not currently in stock, our global sourcing network covers North America, Europe, Japan, and Southeast Asia.

Quality Control for the CPS Series Range

CPS Series power supply modules present specific test challenges due to their integrated backplane connector interfaces and multi-rail DC output architecture. DriveKNMS applies the following test protocol to all CPS units prior to shipment:

• Input voltage sweep test across rated AC input range (85–264VAC) to verify regulation stability
• Full-load DC output test at rated wattage with calibrated electronic load bank, measuring output voltage deviation and ripple
• Overcurrent protection trip-point verification: unit must shut down within specification and recover on reset
• Soft-start timing measurement to confirm inrush current limiting is functional
• Backplane connector pin continuity and insulation resistance test
• Thermal soak at 50°C ambient for 30 minutes under full load to screen latent component failures
• LED status indicator functional check across normal, fault, and overload states

All test data is logged and available upon request with shipment documentation.
