The CPS-150F is identified as a dedicated control power supply for Yaskawa MOTOMAN XRC and NX100 robot controller cabinets. Its input rating is consistently reported as approximately 200–230 VAC, 50/60 Hz, with +5 VDC and +24 VDC control-power outputs.

Yaskawa CPS-150F
Product Introduction (Anti-Template)
When a legacy MOTOMAN controller loses its control-power supply, the robot may stop responding even though the servo amplifiers and mechanical system remain intact. The Yaskawa CPS-150F is a rack-mounted control power supply used with YASNAC XRC and NX100 robot controller systems. It supplies the DC voltages required by the controller electronics, I/O contactor unit, and programming pendant.
The unit accepts approximately 200–230 VAC and provides separate +5 VDC and +24 VDC output groups. Front-panel indicators help identify power, overcurrent, overvoltage, and overtemperature conditions. This is a system-specific power module, not a generic universal AC/DC supply; the controller family and connector arrangement must be confirmed before replacement.
QC, Procurement & Logistics SOP
- Inbound Verification
Check the nameplate for CPS-150F, Yaskawa identification, serial number, voltage rating, and revision markings. Compare the connector positions and rack-mounting structure with the existing unit. - Controller Compatibility Verification
Confirm whether the installed robot controller is an XRC or NX100 system. Do not approve a replacement solely because it is labeled Yaskawa power supply. - Live Rig Testing
With an approved test setup, verify AC input acceptance, +5 VDC output, +24 VDC output, indicator operation, startup behavior, and abnormal heating. Confirm that the power supply does not trigger overcurrent or overtemperature alarms. - QA & Anti-Static Packaging
Protect the front-panel controls, rack connectors, terminal areas, and internal electronic assemblies from impact and ESD. Use anti-static protection where applicable and immobilize the unit inside the shipping carton. - Global Logistics & Export Compliance
Confirm packed dimensions and gross weight before freight booking. Use the appropriate HS classification for an industrial control power supply and ensure that the package protects the rack rails, connectors, and front panel during air or sea transportation.

Technical Pitfalls & Integration Warnings
- Firmware / Controller Revision Mismatch
The CPS-150F is a power supply rather than a firmware-bearing CPU, but the host controller may have revision-specific power and interface requirements. Example: a replacement powers up but does not correctly support the installed XRC or NX100 rack configuration. - DIP Switch / Configuration Errors
Do not assume that all Yaskawa rack power units use the same internal settings or protection arrangement. Confirm the exact model and any revision markings before changing internal settings. - Wiring / Terminal Incompatibility
The unit supplies both +5 VDC and +24 VDC. Incorrectly connecting the output harness, or confusing the two DC output groups, can damage controller electronics. The input voltage and connector pinout must be checked against the cabinet documentation. - ESD and Uncontrolled Unboxing
The internal power circuitry and connector contacts can be damaged by static discharge or rough handling. Disconnect all power before removal, and do not pull on cables or connectors while extracting the module from the rack.

Frequently Asked Questions (FAQ)
Q1. Which robot controllers use the Yaskawa CPS-150F?
The is associated with Yaskawa MOTOMAN XRC and NX100 robot controller systems.
Q2. What is the input voltage?
The commonly documented input rating is 200–230 VAC at 50/60 Hz, with an input current of approximately 2.1 A.
Q3. What DC outputs does it provide?
The unit provides +5 VDC and +24 VDC control-power outputs. One technical record lists the output groups as +5 VDC at 10 A and +24 VDC at 4.0 A.
Q4. Is a generic 150 W power supply?
No. It is a rack-mounted, controller-specific Yaskawa control power supply. Generic power supplies should not be substituted without confirming output voltages, current capacity, connector pinout, mounting, and protection behavior.
Q5. Can it be hot-swapped?
Do not hot-swap the . The available removal procedure requires disconnecting the cables and removing the power unit from the rack. Isolate and verify the cabinet power is off before replacement.
Q6. What should I provide when requesting a replacement?
Provide the complete model , a clear nameplate photograph, the robot controller model, connector-side photographs, and the existing power supply’s input/output ratings.
Q7. Can it be shipped internationally by express air freight?
Yes, subject to destination import requirements and carrier acceptance. Use the final packed dimensions and gross weight for freight calculation; available records place the bare unit at approximately 2.0–2.27 kg.
