Overview
The VT-42-INV Series is a DC-to-AC inverter designed for telecommunication power systems, providing a stable pure sine wave AC output. The unit features a 19-inch, 2U rack-mount design, making it suitable for telecom racks, power cabinets and backup power systems.
The series includes VT-42-INV2000 and VT-42-INV3000 models for different AC load requirements. An integrated ATS (Automatic Transfer Switch) provides automatic source transfer between utility AC and inverter power, improving power availability for critical loads.
Feature
