Lithium Battery UPS for Data Centers and Telecom Base Stations: 3

Modern digital infrastructure lives or dies by the quality of its backup power. A data center that loses a rack of servers for even a few seconds can trigger cascading failures, while a telecom base station that goes dark in a remote valley may leave an entire region without coverage. In both worlds, the Lithium Battery UPS has emerged as the technology of choice—not only because it shrinks footprint and extends service life, but because it enables the unattended, high-availability operation that operators now take for granted. High Idea Power, a manufacturer dedicated to UPS and power-conversion equipment, addresses these two very different environments with two purpose-built products: the 33ET10-60KVA three-in/three-out online Lithium Battery UPS for data centers, and the ET1-3KR rack-mounted integrated Lithium Battery UPS for telecom base stations and edge sites. This article examines both products in depth, with real specification data and the application scenarios where each one earns its keep.

33ET10-60KVA: Three-Phase Lithium Battery UPS for Data Centers

The 33ET10-60KVA series is a high-power, rack-mounted online UPS covering 10 KVA to 60 KVA, built on a three-in/three-out architecture. It is designed for the demanding loads of modern data centers, where balanced three-phase power, high power density, and remote management are non-negotiable.

Key Specifications and Design

• **Output power factor of 1.0**, giving the UPS stronger load-bearing capacity than conventional units and allowing it to power more IT equipment at the same KVA rating.
• **Three-in/three-out topology** with balanced input current across the three phases, which helps balance the load on the three-phase utility grid and reduces neutral current issues.
• **Full digital control** across every stage of the architecture, delivering high stability, self-protection, and fault-diagnosis capability while eliminating the drift and failure risks associated with analog components.
• **Configurable charging current**: battery capacity can be set through computer software, and the maximum charging current is software-adjustable. Constant-voltage, constant-current, and float charging modes switch automatically and smoothly.
• **Two-stage, three-phase intelligent charging**: a high-current constant-current stage quickly restores about 90% of battery capacity, followed by constant-voltage charging to fully charge the cells, and finally float charging—balancing fast recharge with extended battery life.
• **LCD and LED displays** showing input/output voltage and frequency, load level, battery capacity, and internal temperature at a glance.
• **SNMP-based remote monitoring** for centralized visibility across the fleet.
• **EPO/REPO emergency power-off** interface on the rear panel, allowing an external EPO button or remote emergency power-off for safety-critical shutdowns.

Why Lithium Batteries Matter Here

The 33ET series is designed to pair with lithium iron phosphate (LFP) batteries. Compared with lead-acid banks, LFP packs occupy far less floor space, deliver a longer service life, and tolerate higher operating temperatures—three properties that translate directly into lower total cost of ownership in a data center, where every square meter of raised floor and every cooling watt counts.

Typical Application Scenarios

This Lithium Battery UPS fits naturally into medium and large data centers, server rooms, and enterprise IT facilities that run three-phase power. Its rack-mounted form factor and balanced three-phase input make it well suited to modular data hall designs, while the EPO/REPO function satisfies the emergency-shutdown requirements of modern facility codes.

ET1-3KR: Integrated Lithium Battery UPS for Telecom and Edge Sites

The ET1-3KR is a rack-mounted UPS with a built-in Class A lithium iron phosphate battery, engineered for the harsh, often unattended environments of telecom base stations, remote sites, and edge computing nodes. It is a true “all-in-one” backup solution: no external battery cabinet, no separate battery room, no routine maintenance.

Key Specifications and Design

• **Wide input voltage range of 110 VAC to 300 VAC** with a wide frequency range, plus built-in three- or four-level lightning protection, allowing normal operation even in harsh electrical environments.
• **Active PFC technology** to reduce pollution fed back to the utility grid and improve input power quality.
• **Automatic power-on**: the unit powers on automatically when mains returns, eliminating outages caused by operators forgetting to restart equipment—a critical feature for unattended base stations.
• **Integrated high-capacity Class A LFP battery** with a float-charge life of over 10 years and a cycle life of over 1200 cycles. The battery is maintenance-free, small, and lightweight, delivering a **full-load backup time of ≥30 minutes**—far superior to the 5–10 minutes typical of lead-acid designs.
• **DSP digital control** with a fully digital central processing chip for precise, rapid data processing and strong load capacity.
• **Online dual-conversion architecture with zero transition time** between mains, battery, and bypass modes, ensuring uninterrupted, clean power to the load.
• **Generator-friendly design**: a wide input frequency range (up to ±10 Hz) makes it easy to match with various generators, isolating poor generator power and delivering pure, stable output.
• **Flexible output settings**: output voltage selectable at 208/220/230/240 VAC with automatic 50/60 Hz adaptation, eliminating the need for country-specific customization.
• **Intelligent management**: standard RS232 interface with cloud IoT expansion, centralized and mobile monitoring, Modbus485 and dry-contact options, remote power-on/off, automatic shutdown of computers, servers, and virtual machines during outages, and compatibility with NAS server communication.

Typical Application Scenarios

The ET1-3KR is built for telecom base stations, communication shelters, remote monitoring sites, and edge computing nodes. Its automatic power-on, wide input tolerance, lightning protection, and long-life integrated battery make it ideal for locations where a technician may visit only once or twice a year. The same characteristics also suit small server rooms and branch offices that want lithium-battery reliability without the complexity of a separate battery cabinet.

Choosing the Right Lithium Battery UPS for Your Site

When planning backup power for digital infrastructure, the decision usually comes down to scale and environment:

• Choose the **33ET10-60KVA** when you need three-phase, high-power protection for a data center or large server room, with balanced phase loading, software-configurable charging, and EPO/REPO safety functions.
• Choose the **ET1-3KR** when you need a compact, self-contained **Lithium Battery UPS** for a telecom base station, edge site, or small server room, where unattended operation, wide input tolerance, and long battery life matter most.
• For sites that already run a DC bus, High Idea Power’s rack-mounted **Inverter** products (such as the H1-10K DC-to-AC series) complement these UPS units by converting DC power into clean AC for communication and control loads—together forming a layered AC/DC backup architecture.

Conclusion

High Idea Power covers the full spectrum of modern backup power with its Lithium Battery UPS portfolio. The 33ET10-60KVA brings three-phase, high-power protection and intelligent charging to data centers, while the ET1-3KR delivers a maintenance-free, long-life integrated lithium solution to telecom and edge sites. By matching the right product to the right environment, operators gain measurable improvements in uptime, footprint, and long-term operating cost—backed by real, verifiable specifications.
