MP3100 Series Three-Phase In Single-Phase Out Online UPS – High Reliability Power Protection for Critical Infrastructure

The MP3100 Series is a robust, low-frequency online uninterruptible power supply (UPS) designed for industrial and commercial environments where consistent, high-quality electrical output is essential. With capacities ranging from 6kVA to 60kVA, this three-phase input to single-phase output system offers reliable power conditioning for sensitive equipment across diverse sectors including telecommunications, healthcare, manufacturing, banking, and data centers. Engineered with advanced digital control technology, it ensures seamless operation even under fluctuating grid conditions or sudden load changes.

At the heart of the MP3100 lies a true double-conversion topology that delivers pure sine wave output, minimizing harmonic distortion and ensuring compatibility with non-linear loads such as motors, air conditioning units, printers, and industrial machinery. The system employs high-speed microprocessors (MCU), programmable logic devices (CPLD), and IGBT-based PWM inverter technology to provide up to 93% efficiency at full load—reducing energy waste while enhancing thermal performance. Its intelligent battery management system extends battery life through adaptive charging algorithms and real-time monitoring, supporting both lead-acid and Lifepo4 Battery configurations for flexible deployment options.

Key features include a comprehensive LED + LCD interface for intuitive diagnostics, automatic self-testing routines, and an event log storing up to 256 detailed operational records. The unit supports multiple working modes—including standard UPS, ECO mode for improved efficiency, and inverter-only mode—allowing users to optimize performance based on power availability and cost considerations. A static bypass switch enables instantaneous transfer during overload or fault scenarios, ensuring continuous operation without interruption. Optional N+1 parallel redundancy increases system reliability, making it ideal for mission-critical applications requiring uninterrupted uptime.

Designed for global use, the MP3100 accepts various input voltages (380V/400V/415V AC or customizable 200–240V AC) and frequencies (50Hz or 60Hz ±10%), accommodating regional power standards worldwide. It also includes surge protection rated at 20kA (8/20μs), isolation resistance exceeding 3MΩ at 500VDC, and IP31 protection against dust and splashing water—making it suitable for indoor installations in demanding environments. The unit’s cooling system uses temperature-controlled forced ventilation to maintain optimal operating temperatures between 0°C and 40°C, with humidity tolerance from 30% to 90% relative humidity.

This versatile UPS finds application in telecom infrastructure, medical imaging systems, server rooms, industrial automation lines, transportation hubs, and government facilities. Whether protecting legacy equipment or modern IT infrastructure, the MP3100 provides stable voltage regulation (±1% under steady load), fast dynamic response (<10ms recovery time), and precise frequency stability (±0.5%). It supports remote monitoring via RS232/RS485 interfaces, optional SNMP cards, or dry contact signals, enabling proactive maintenance and centralized oversight.

Users appreciate its silent yet efficient operation—noise levels range from 45dB to 60dB depending on model size—and the modular design allows easy servicing and component replacement. The built-in auto-restart function ensures quick resumption after mains restoration, while comprehensive protections cover overvoltage, undervoltage, short circuits, overloads, battery faults, and overheating events. For those seeking scalable solutions, the option to add external battery modules or integrate into redundant parallel setups makes the MP3100 a future-proof investment in power resilience.

Common questions often revolve around compatibility with generators (the MP3100 excels here due to its wide input voltage range and phase synchronization capabilities), ease of installation (modular cabinets simplify setup), and long-term cost savings (thanks to high efficiency and extended battery life). Unlike cheaper alternatives, this series doesn’t compromise on build quality or software intelligence—offering a balance of performance, durability, and smart automation that meets international standards for critical power applications.
