System compatibility

CPS-20NB belongs to Yaskawa MP motion control system family,matched with CG series control boards and CACR-SR series servo drives. Widely used in chip mounters,precision X-Y positioning platforms and special automation equipment. This is a discontinued legacy power supply unit for old production line maintenance spare replacement.

Function

CPS-20NB serves as dedicated rack power supply for motion control system. It converts AC input into stable DC5V and DC24V power to supply main control board, I/O boards and communication modules. Built-in multi-level hardware protection including overvoltage,overcurrent,short-circuit and overheat protection to guarantee stable system operation.

Installation

Mount CPS-20NB in controller rack. Wire AC input and DC backplane connection according to wiring drawing. Complete power inspection before powering on the whole control system.

Interface

‑AC input terminal block

‑Backplane connector for DC power output

‑Front panel LED indicators for power and fault alarm

‑Onboard power monitoring and protection circuit

Circuit feature

Compact rugged PCB layout,equipped with surge and ESD suppression circuit. Stable dual DC output,strong anti-interference performance for industrial cabinet environment.

Feature

CPS-20NB is obsolete Yaskawa MP series power supply spare part. Typical failures include power board damage,output loss and overheating faults. Check module integrity before replacement. Must match corresponding controller rack,direct substitution without hardware validation is not recommended.

Diagnostic

When overvoltage,overcurrent,overheat,DC output loss or short circuit occurs,the module triggers corresponding alarm signals and sends fault status to upper controller.

Built‑in function

AC-DC dual channel power conversion,real-time power status monitoring,multi-level hardware fault protection for motion control system,used as controller power supply spare replacement.

Product Brief

CPS-20NB is Yaskawa MP series rack power supply module for dedicated semiconductor and precision automation machinery. Confirm rack system matching before ordering. ESD protection required during handling and installation.
