Metallurgical rolling mill, wind power converter, water and electricity speed controller

Complete control system for large-scale chemical compressors and high-power motors

6、 Supply and replacement instructions

Spot goods source

Brand new original inventory: 12-month warranty; Refurbished parts with a warranty of 3-6 months, high risk

Compatible with alternative models

Upgraded version of the same series: PCD232A, with fully compatible hardware pins and installation dimensions, stronger performance, and some items can be directly replaced; It is recommended to use the new generation AC800PEC controller for the new project, and no longer purchase the discontinued module of PCD230A.

Procurement Tips

The prices of discontinued spare parts continue to rise, and it is recommended to stock up in bulk for the renovation of old units to avoid downtime without spare parts in the later stage.
