Fanuc A06B-6083-H245 ALPHA High Voltage Capacitor Module. This HV power supply backup PSMC-45HV is used within larger machines with 400v 3 phase. This capacitor module acts as a storage bank for the same kW rated PSM such as the A06B-6091 series HV modules. DNC offer several services for the PSM-45HV and its capacitor PSMC, however the capacitors are relatively simple devices compared to the Power Supply Module s, and normally its the PSM that fail rather than the PSMC-45HV. DNC offer exchange (assuming in stock), fault finding and testing of these modules, and repair if necessary. We have all of the necessary PSM and SPM high voltage modules to effect a reliable testing environment.
