In an era where digital operations and precision equipment dominate, power outages pose a silent threat to data security and business continuity. The HIGHIDEA ET1K online lithium UPS uninterruptible power supply emerges as a robust solution, delivering reliable power protection for small servers, office systems, and commercial terminals.
As a 1KVA online UPS, the ET1K employs a double-conversion architecture to achieve AC-DC-AC pure sine wave output, eliminating issues like voltage fluctuations, harmonic interference, and transient power failures. Its standout feature is the zero-second transfer technology, which seamlessly switches to lithium battery power during mains anomalies, ensuring continuous operation of critical loads such as servers and network devices—preventing data loss or service interruptions. The built-in 36V/15AH lithium iron phosphate (LiFePO4) battery offers higher energy density and an impressive 2,000 charge-discharge cycles, reducing maintenance costs by 70% compared to traditional lead-acid batteries.
Intelligent voltage regulation is another core strength. The device automatically adjusts output voltage to 220V±1% across a wide input range (110V–300V), effectively addressing unstable grid conditions. Equipped with a standard network monitoring card, it supports SNMP protocols and mobile app remote management, enabling real-time monitoring of load rates, battery status, and fault alerts for proactive maintenance. For noise-sensitive office environments, a one-touch silent mode reduces operational noise to below 45dB, creating a quieter workspace.
With compact dimensions (355×145×220mm) and lightweight design (8.6kg), the ET1K fits easily into server racks or desktop setups. Its 800W output capacity sustains a 700W server for 30 minutes while supporting 2–3 office computers, POS systems, or surveillance devices during outages. Ideal applications include power backup for SME servers, retail POS protection, and SOHO office environments.
Technically, the ET1K delivers full-range 220VAC input/output synchronization, with a transfer time of <2ms and an output power factor of 0.8, achieving 92% efficiency. The LiFePO4 battery supports rapid charging (90% capacity in 2 hours) and prioritizes environmental safety. For users seeking reliability and cost-effectiveness, this product redefines the benchmark for small UPS systems, serving as an indispensable power guardian for critical equipment in the digital age.
