50-400kW Eight-Slot UPS：
The AC400/50 50-400kW Eight-Slot UPS is designed for high-performance power protection with a 3-phase + N line + PE input wiring configuration. It supports a wide input voltage range of 304-478VAC (line voltage) at full load, with a linear derating from 100% to 50% when the voltage drops to 304~228VAC. The bypass voltage range is customizable, with default settings from -20% to +15%, and can be adjusted for different voltage limits. Featuring a user-friendly 10-inch color LCD touch screen combined with LED indicators, it offers clear real-time monitoring. With a working temperature range of 0-40°C and storage temperatures from -25°C to 70°C, the AC400/50 is built to operate reliably in various environments and conditions.
