NewTrend · automatic voltage conditioner
Product overview
NewTrend Y-AVC uses an AC-DC-AC converter and a series compensation transformer to regulate load-side voltage. The AC220V L/N+PE platform is rated30kVA and135A. The AC380V three-phase four-wire+PE platform covers catalogue ranges of30–500kVA and45–750A, with exact capacity configured for the application. Standard compensation is±20% of nominal voltage; the wider-40% to+30% compensation range is described as customization.

Operation
- The converter regulates the magnitude and polarity of voltage applied through a compensation transformer connected in series with the main circuit.
- Voltage is controlled continuously and by phase. The circuit includes a breaker, contactor and bypass switching for the stated maintenance arrangement.
- The input voltage envelope and standard compensation range are separate catalogue values. Confirm required capacity and voltage-event depth and duration for the application.
Typical applications
- Industrial loads requiring stable supply voltage
- Facilities exposed to voltage deviation or phase-unbalanced loading
- Applications requiring electronic voltage compensation with a maintenance bypass arrangement

The photograph is the original AVC cabinet-family example. The ordering-code guide illustrates three-phase4L coding and lists selected example capacities; the latest technical table separately specifies the220V single-phase30kVA platform and the380V30–500kVA range. Exact three-phase capacity, current and cabinet arrangement are confirmed for the project. Installation and wiring must be performed by qualified electricians.
