SmartOnline S3MX Series 3-Phase 380/400/415V 30kVA 27kW On-Line Double-Conversion UPS, Parallel for Capacity and Redundancy, Single & Dual AC Input, With 12V-9Ah Delta Batteries

Description Overview

The SmartOnline S3MX Series 30kVA 27kW UPS is a high-performance three-phase online double-conversion power protection system designed for mission-critical applications. It delivers clean and continuous power by converting incoming AC to DC and back to AC, eliminating voltage fluctuations, noise, and power disturbances. This ensures sensitive equipment such as data centers, industrial systems, and telecommunications infrastructure operate without interruption.

With support for 380/400/415V input and output, the unit provides 30kVA (27kW) capacity in a compact tower footprint. It features advanced DSP-controlled IGBT technology, voltage-frequency independent (VFI) operation, and high efficiency up to approximately 94% in double-conversion mode to reduce operating costs.

The UPS supports parallel operation for both increased capacity and N+1 redundancy, allowing multiple units to work together for scalable deployment. It also offers single and dual AC input configurations, battery-sharing capability, and compatibility with external battery cabinets for extended runtime. Built-in static and maintenance bypass further enhance system availability by transferring loads to utility power during faults or maintenance.

An intuitive LCD interface provides real-time status monitoring, including load level, battery charge, input/output voltage, and runtime information. The system supports network management options for remote monitoring, making it suitable for IT environments, finance, telecom, industrial automation, and other critical applications requiring reliable three-phase power protection.
