Legacy Phase Perfect - Filter Capacitor Service Kit
Legacy Phase Perfect units, including the PT330, PT355, PT380, PT3110, and PT3160 require periodic replacement of the line filter capacitors. Newer Phase Perfect's, those in production since 2019, have upgraded film type line filter capacitors that should be checked regularly, but are designed for a significant service life.
Prior to replacement, the installed filter capacitors should be visually inspected. 370VAC and 480VAC capacitors have different diameters and are not interchangeable. A bracket is available for the PT380 and PT3160 to upgrade from 370VAC capacitors to 480VAC capacitors. A 240V Phase Perfect may be equipped with either 370VAC or 480VAC capacitors.
Line filter capacitors should be inspected annually at a minimum. If the equipment is frequently operated under heavy load, inspection every six months is recommended.
Important: Do not operate the Phase Perfect® with degraded line filter capacitors.
Replacement of the capacitors every three years is recommended. These capacitors suppress electrical noise caused by the switching of the IGBTs. If they are degraded the electrical noise can damage equipment connected to the converter. Line filter capacitors should be visually inspected and electrically tested on a routine basis. For full testing details please see your Phase Perfect owners manual.
Service kit includes 1 complete set of filter capacitors.
