1000VA Offline UPS

The AK 1000VA Offline UPS is designed for users who require both higher capacity and longer runtime. With dual batteries, it offers nearly double the backup energy of single‑battery models, making it suitable for powering three to four desktop computers, networking equipment, and external storage devices simultaneously.

The CPU‑controlled integrated power board ensures stable output, while the laminated power transformer – made of brand‑new silicon steel and high‑quality winding – guarantees high efficiency and robust power capability. The unit also features an optional communication port (RS232/USB/RJ45) for advanced power management and remote monitoring.

Core Advantages

1. Dual‑Battery Configuration for Extended Runtime

Two 12V/7Ah batteries connected in series provide 24V nominal battery voltage, significantly increasing stored energy. This translates to longer backup times – up to 15‑20 minutes at half load – allowing you to complete critical tasks without rushing.

2. High‑Efficiency Laminated Transformer

The EI‑type transformer, constructed from premium silicon steel and copper windings, minimises losses and delivers stable power even under heavy loads. This design ensures low heat generation and long operational life.

3. Comprehensive Load Protection

With 600W capacity, the AK 1000VA Offline UPS can support multiple monitors, a powerful workstation, a NAS, and a network switch all at once. Its overload protection kicks in automatically to prevent damage from excessive loads.

4. Flexible Monitoring and Control

Optional RS232, USB, or RJ45 communication ports allow integration with UPS management software, enabling automatic shutdown of connected devices during extended outages – preventing data loss and system corruption.

Key Application

1. Small Office Workstations – Protect two desktop PCs, monitors, and shared printers.

2. Network Hubs – Keep routers, switches, and NAS devices online during brief outages.

3. Retail Checkout Counters – Ensure POS terminals and barcode scanners remain powered to avoid sales disruption.

4. Security Systems – Maintain CCTV cameras and DVRs recording during power dips.

FAQ

1. Can the AK 1000VA Offline UPS support a server with redundant power supplies?

Yes, as long as total power draw stays under 600W. It is suitable for tower servers and small rack‑mount systems.

2. How long does it take to recharge after a full discharge?

Typically 8 hours to reach 90% capacity. The smart charger prevents overcharging and extends battery life.

3. What communication options are available?

Standard models come with no communication port, but optional RS232, USB, or RJ45 with management software can be added – please specify at order.

4. Can the AK-1000VA power a laser printer or copier?

Laser printers and copiers have high inrush current during startup, often 5 to 10 times their rated power. While the AK-1000VA can handle short surges, we recommend connecting laser printers to a separate surge protector rather than the UPS battery output. Inkjet printers and small multifunction devices are generally safe to connect, provided the total load stays below 600W.

5. What is the difference between the AK-1000VA and connecting two smaller UPS units in parallel?

The AK-1000VA uses dual batteries in series within a single unit, providing coordinated battery management, single-point monitoring, and a compact footprint. Two separate UPS units would require separate power cords, occupy more space, and lack synchronized shutdown capabilities. The integrated design also ensures balanced charging between the two batteries, extending overall battery life.

6. The UPS emits a continuous beep after a prolonged outage. What does this mean?

A continuous beep indicates the battery voltage has dropped to the low-voltage cutoff point. The UPS has automatically shut down to prevent deep discharge damage to the batteries. When mains power is restored, the UPS will resume charging automatically. No manual intervention is required. If the continuous beep persists after power restoration, please contact our support team.

7. Can I replace the batteries myself when they reach end of life?

Yes, the AK-1000VA is designed with user-replaceable batteries. The front panel can be opened to access the two 12V/7Ah batteries. Please ensure you replace both batteries at the same time with identical specifications. Mixing old and new batteries or using different capacities will reduce performance and may cause charging imbalance. Always disconnect the UPS from mains power before opening the compartment.

8. Does the AK-1000VA provide surge protection for network and phone lines?

Optional RJ45 and RJ11 ports are available for protecting network and telephone connections. These ports filter surges on data lines to prevent damage to connected networking equipment. Please specify your requirement when ordering, as this feature is not included in the standard configuration.

9. How does the AVR function differ between the AK-1000VA and the smaller AK-500VA models?

The AVR circuit design is identical across the AK series, providing the same boost and buck regulation range (81-145V or 145-275V). The primary difference is the power handling capacity. The AK-1000VA's AVR components are rated for higher current, allowing it to regulate voltage for loads up to 600W without additional stress on the circuit.

10. What is the expected lifespan of the UPS itself, beyond the batteries?

The AK 1000VA Line Interactive UPS is built with a laminated EI-type transformer and high-quality power components rated for 10+ years of continuous operation under normal conditions. The batteries typically require replacement every 3 to 5 years, but the electronics and transformer are designed to outlast multiple battery replacement cycles, making this a long-term investment for your power protection needs.
