3000VA Line Interactive UPS

The 3000VA Line Interactive UPS is the largest and most powerful offline UPS in the AK series, capable of supporting heavy loads such as multiple servers, large network switches, industrial controllers, and even small air‑conditioning units (with proper derating). Its four 12V/9Ah batteries provide a total capacity of 432Wh, offering up to 20‑25 minutes of runtime at half load and 8‑10 minutes at full load – sufficient for most critical applications to complete emergency shutdowns or transfer to generator power. The unit’s robust construction, intelligent cooling, and precision voltage regulation make it a reliable guardian for high‑value equipment.

Core Advantages：

1. Maximum Power Capacity (1800W)

The AK‑3000VA can handle the most power‑hungry devices – from rack‑mount servers and storage arrays to large‑format printers and medical diagnostic machines. Its headroom ensures stable operation even when loads fluctuate.

2. Longest Runtime in the Series

With four 9Ah batteries, this model provides the highest stored energy. At 50% load (900W), runtime exceeds 20 minutes, giving operators ample time to save data and safely power down systems.

3. Industrial‑Grade Transformer and Cooling

The oversized laminated transformer, built with high‑grade silicon steel, delivers exceptional efficiency and minimal temperature rise. The unit’s large chassis allows for natural convection cooling, reducing reliance on fans and ensuring silent operation (≤40dB).

4. Advanced Protection and Monitoring

In addition to standard short‑circuit, overload, and low‑battery protection, the AK‑3000VA features over‑voltage and under‑voltage cut‑off. Optional communication ports (RS232/USB/RJ45) enable remote monitoring, event logging, and automatic shutdown via UPS management software – essential for unattended facilities.

Key Features

1. Large Data Centres – Protect multiple racks of servers, storage, and networking equipment.

2. Medical Imaging – Ensure CT scanners, MRI consoles, and ultrasound machines remain operational during power anomalies.

3. Industrial Manufacturing – Support PLCs, robotic controllers, and conveyor systems in production lines.

4. Telecom Central Offices – Provide backup for high‑capacity switches and transmission equipment.

5. Critical Infrastructure – Power emergency communication systems, traffic control, and security operations.

Product Parameter

Why Choose the AK‑3000VA?

The AK‑3000VA is the ultimate offline UPS for customers who require the highest power and longest runtime in a single, cost‑effective package. It offers a 50% power increase over the AK‑2000VA model, making it suitable for enterprise‑grade applications. Despite its power, it retains the same compact footprint as the 2000VA version, saving valuable floor space. Its robust design and generous battery bank make it the preferred choice for facilities where every second of uptime counts.

FAQ

1. Can the AK‑3000VA be connected in parallel for even higher power?

No, the AK series does not support parallel operation. For higher power, please consider our online UPS series.

2. How long does it take to recharge the four 9Ah batteries?

The standard recharge time is 8 hours to 90% capacity. The charger is designed to prevent overcharging, ensuring long battery life.

3. Is the output pure sine wave?

No, this is a simulated (stepped) sine wave. For pure sine wave requirements, we recommend our online UPS models. However, simulated sine wave is sufficient for most switching power supplies and modern electronics.

4. What is the typical maintenance interval?

We recommend checking battery condition every 6‑12 months. The unit is maintenance‑free except for battery replacement every 3‑5 years, depending on usage and ambient temperature.
