Must EH55-H1K2 1KVA Online UPS — High-Frequency Double Conversion Power Protection for Home and Office

The Must EH55-H1K2 1KVA Online UPS is a new-generation, high-frequency double-conversion uninterruptible power supply from Must's trusted EH5500 series. Built with advanced DSP digital control technology, it delivers superior power quality, higher system reliability, and exceptional energy efficiency in a compact and lightweight tower design. Whether for a home office, small business, or networking room, the EH55-H1K2 is engineered to keep your equipment running safely through every type of power disturbance.

True Online Double Conversion with Zero Transfer Time

At the heart of the EH55-H1K2 is a true online double-conversion design that continuously regenerates the AC output from a clean DC source. This means all connected devices are always isolated from raw mains power — protected from blackouts, brownouts, sags, surges, voltage spikes, harmonic distortion, and frequency fluctuations at all times. The switch to battery mode occurs in 0ms, meaning there is absolutely no interruption to connected equipment even during a sudden and complete power failure.

Ultra-Wide Input Voltage Range

With an input voltage range of 110V to 300V AC, the EH55-H1K2 can sustain normal operation through severe grid voltage swings without switching to battery unnecessarily. This ultra-wide tolerance preserves battery life and extends the overall lifespan of the unit — a vital feature in areas where power quality is inconsistent.

Output Power Factor of 1.0 and High Efficiency

The EH55-H1K2 boasts an output power factor of 1.0 and an AC mode efficiency of 94.5% at full load, significantly reducing energy losses and operating costs. The active power factor correction (PFC) technology at the input ensures the input power factor is close to 1, minimizing pollution to the utility grid and reducing the strain on connected electrical infrastructure.

Advanced DSP Digital Control Technology

The use of digital signal processor (DSP) control technology ensures precise, fast, and reliable power regulation under all conditions. It delivers consistent output voltage accuracy of ±1% and output harmonic distortion of just ≤2% for linear loads, making it suitable for even the most sensitive electronic equipment.

Flexible Battery Configuration and Intelligent Charging

The EH55-H1K2 comes with two or three sealed lead-acid batteries (12V/7Ah each), providing backup power for safe shutdown or short-duration operation. The two-stage and three-stage intelligent charging system optimizes battery charging cycles to extend battery lifespan and maintain consistent performance over time.

Generator Compatibility and Cold Start

The EH55-H1K2 supports a wide input frequency range of 40~70 Hz, making it fully compatible with various fuel generators for extended backup scenarios. The cold start function allows the UPS to power connected devices directly from the battery without requiring mains input — ensuring equipment can be brought online even during a complete blackout.

Comprehensive Protection and Self-Detection

The UPS provides multi-layer protection including over-voltage, under-voltage, overload, short circuit, over-temperature, battery low-voltage warning, and battery overcharge protection. A built-in self-detection function identifies hidden faults at startup, giving administrators confidence in the unit's readiness at all times.

LCD + LED Display and Communication Options

The intuitive LCD and LED display shows real-time information on operating mode, load level, input/output voltage, and battery status. Standard RS-232 and USB ports enable monitoring and management from Windows, Linux, Unix, and MAC operating systems. An optional intelligent slot supports SNMP cards, AS400 relay cards, and RS485 for advanced network-based monitoring and management.

Ideal Applications

The Must EH55-H1K2 is well suited for home offices, desktop computers, laptops, networking equipment, routers, switches, CCTV systems, NAS devices, POS systems, and any other sensitive electronics requiring dependable, clean, and continuous power protection.
