2000VA Offline UPS

The AK 2000VA Offline UPS is the largest offline UPS in the standard AK series, offering ample power for multiple servers, network switches, and other critical loads. Its four-battery configuration provides a total voltage of 48V, delivering the longest runtime among all models – up to 30 minutes at half load.

The advanced CPU controller monitors input quality and automatically boosts or bucks voltage, preserving battery life for true emergencies. The unit’s spacious interior allows for efficient heat dissipation, and the high-quality laminated transformer ensures low losses even under continuous heavy loads.

Key Features

1. Massive Battery Bank for Extended Autonomy

With four 12V/7Ah batteries (or upgraded 9Ah), the AK-2000VA offers the longest backup time in the series. At 50% load (600W), it can sustain power for 25-30 minutes – enough to ride through most short outages or perform a systematic shutdown of entire server racks.

2. High Power Output (1200W)

This capacity can support up to six standard desktop PCs, a small server, network switches, and monitors simultaneously. 2000VA Offline UPS is also suitable for powering industrial equipment, such as PLCs and process controllers.

3. Superior Transformer Efficiency

The custom-wound EI transformer, using premium materials, ensures minimal heat generation and maximum power transfer. This design not only improves efficiency but also extends the life of the unit in continuous operation.

4. Flexible Communication and Monitoring

Optional RS232, USB, or RJ45 ports allow integration with UPS management software, enabling remote monitoring, scheduled shutdowns, and event logging. This is essential for data centres where unattended operation is the norm.

Key Application Scenarios

1. Small Data Centres

Protect server racks, storage arrays, and network switches from power interruptions. In data centre environments, even a momentary outage can corrupt active transactions or cause RAID array rebuilds. The AK-2000VA's 1200W capacity supports up to six standard servers or a compact storage area network (SAN) enclosure, providing sufficient runtime for graceful virtual machine migration or orderly system shutdown.

2. Telecommunication Base Stations

Ensure uninterrupted operation of transceivers, microwave links, and backhaul equipment. Telecom infrastructure often operates in remote locations where grid reliability is poor. The four-battery configuration delivers extended runtime to maintain network connectivity during prolonged outages, preventing service blackouts that affect hundreds or thousands of subscribers.

3. Industrial Automation

Provide backup power for PLCs, HMIs, motor drives, and process controllers in manufacturing plants. Industrial environments often experience voltage sags caused by heavy machinery startup. The AK-2000VA's AVR circuit stabilises incoming voltage without draining the battery, while the 6-10ms transfer time prevents control system resets that could halt production lines.

4. Emergency Lighting and Security Systems

Power critical lighting, access control systems, and surveillance equipment in commercial buildings. During grid failures, building codes often require emergency egress lighting to remain operational. The AK-2000VA's high capacity supports multiple lighting circuits and security panels, ensuring compliance with safety regulations and maintaining building security during outages.

2000VA VS 1500VA

The AK 2000VA Offline UPS is the highest-capacity offline UPS in the standard AK series, offering the longest runtime and largest power output. It is designed for users who need substantial backup energy and are willing to invest in a larger physical footprint.

Compared to the AK-1500VA, it provides 33% more power (1200W vs 900W) and nearly double the battery capacity (four 7Ah/9Ah batteries vs two), making it the preferred choice for IT managers, facility operators, and system integrators who require extended runtime for critical infrastructure.

FAQ

1. Can the AK 2000VA Line Interactive UPS be used with a generator?

Yes, but ensure the generator output is stable. The AVR will help regulate voltage, but extremely dirty power may cause the UPS to switch to battery frequently.

2. What is the typical runtime with 9Ah batteries?

With 9Ah batteries, runtime increases by approximately 30% compared to 7Ah. At half load, you can expect over 30 minutes.

3. Does it have a bypass switch for maintenance?

No, this model does not include an internal bypass. For maintenance, you must turn off the UPS and disconnect the load.

4. What is the expected runtime with the standard 7Ah batteries versus the optional 9Ah batteries?

With four 12V/7Ah batteries at 50% load (600W), the AK-2000VA provides approximately 25 to 30 minutes of backup time. Upgrading to four 12V/9Ah batteries increases runtime by approximately 30%, delivering over 30 minutes at the same load. At full load (1200W), runtime is approximately 8 to 10 minutes with 7Ah batteries and 12 to 14 minutes with 9Ah batteries. Actual runtime varies based on battery age, temperature, and load characteristics.

5. Can the batteries be replaced individually if one fails?

No. The four batteries are connected in series to achieve 48V nominal voltage. When one battery fails, the entire battery bank must be replaced as a set. Mixing old and new batteries will cause charging imbalance and significantly reduce overall performance. We recommend replacing all four batteries simultaneously with identical capacity and brand.

6. The UPS is rated at 2000VA but only 1200W. Why is there a difference between VA and Watt ratings?

This difference is due to the power factor of the UPS. The AK-2000VA has a power factor of 0.6 (1200W ÷ 2000VA = 0.6). Many computer power supplies and electronic loads have a power factor between 0.6 and 0.9. When calculating how many devices you can connect, always use the wattage rating (1200W) as your limit, not the VA rating. For example, a server with 0.8 power factor drawing 200W will consume approximately 250VA, allowing up to six such servers on this unit.

7. Can the AK 2000VA Offline UPS support a large-format printer or plotter?

Large-format printers and plotters often have high inrush current during startup, typically 3 to 5 times their rated operating current. While the AK-2000VA can handle moderate surges, we recommend checking the printer's nameplate for starting current specifications. If the total surge demand exceeds 2000VA, consider connecting the printer to a dedicated surge protector or choosing a pure sine wave online UPS for motor-driven printing equipment.
