MPN: A06B-6320-H333 — industrial control spare part, in stock at TGK Parts.
The A06B-6320-H333 is the PSMI-33H power supply module for FANUC αi series amplifiers — the module that rectifies and supplies the DC bus for the whole SVM/SPM group. A failed PSM takes down every axis and spindle in the group, making it one of the highest-urgency surplus items in CNC maintenance.
TGK Parts sources PSMI modules from decommissioned machines worldwide. Where possible we bench-test (rectification, DC bus soft-start, comms) before shipping with a 12-month warranty.

Replacement and spare part for industrial automation equipment — production lines, CNC machines, packaging machinery, textile machinery, printing equipment and more.
No — the PSM supplies the DC bus for the entire amplifier group. A dead PSM means every module in the group is down.
Where possible, yes — soft-start resistor and precharge behavior are part of the bench check; the test level is stated in the quote.
Blown main rectifiers, failed soft-start circuit and fan failure are the top three; several are repairable — ask about repair/exchange.
