FCM-Series Modular Static Frequency Converter

Overview

The FCM-Series converts incoming mains to the frequency a machine actually needs. It accepts anything from 40 to 70 Hz with automatic 50/60 Hz sensing and delivers a selectable 50 or 60 Hz output held to ±0.1%. Five models run from FCM-200 to FCM-600, built from four to twelve 50 kW modules — add modules to raise capacity or to run N+X redundancy, and swap one out while the system stays live. Everything is serviced from the front, so the cabinet can sit against a wall with no rear clearance.

Key Features

• ✓Five models — FCM-200, FCM-300, FCM-400, FCM-500 and FCM-600, built from four to twelve 50 kW modules
