AoKu AKLS Series Line Interactive Pure Sine Wave UPS (1KVA - 5KVA | Standard & Long Backup -L Models)
AoKu AKLS Series Line Interactive Pure Sine Wave UPS (1KVA - 5KVA | Standard & Long Backup -L Models)
The AoKu AKLS Series (1KVA - 5KVA | 800W - 4000W) is a high-performance line-interactive pure sine wave UPS engineered for enterprise server racks, medical diagnostic equipment, and automation controllers. Controlled by double CPU micro-controllers, it delivers clean pure sine wave AC output (PF=0.8), wide AC input range with automatic over/under-voltage battery transfer, and seamless generator compatibility. Standard models include internal lead-acid batteries, while long-backup -L models feature 5A/10A adjustable smart chargers for external battery banks. Includes RJ11/RJ45 surge protection, LCD display, mute setup, and optional RS232/USB telemetry.
KEY FEATURES & BENEFITS
Pure Sine Wave Output & Line-Interactive Topology (PF=0.8)
Delivers clean, distortion-free pure sine wave AC power across all capacity tiers (800W to 4000W). Perfectly compatible with active power factor correction (Active PFC) server power supplies, sensitive medical imaging systems, and inductive motor loads, eliminating overheating, buzzing noise, and hardware stress.
Double CPU Micro-Controller Architecture
Engineered with dual high-performance CPU digital processing chips. Provides real-time line-voltage sensing, high-speed battery transfer, precise PWM inverter regulation, and intelligent fault diagnostics, guaranteeing reliable system stability under severe utility power fluctuations.
Auto Over/Under Voltage Transfer & Generator Matching
Operates across a wide AC input voltage window. When utility voltage surges above or drops below safe threshold limits, the double CPU controller automatically transfers the load to inverter battery power. Fully compatible with backup gasoline and diesel generators for uninterrupted grid-failure operation.
Standard (Internal 12V 7Ah/9Ah) & Long Backup -KL (5A/10A Charger) Options
Standard models integrate sealed lead-acid battery packs (12V 7Ah/9Ah: 2 pcs for 1K/1.5K, 4 pcs for 2K/3K, 8 pcs for 5K). Long-backup models (-L Series) feature an integrated 5A / 10A software-adjustable powerful charger to rapidly recharge high-capacity external battery banks (50Ah–200Ah) for extended outage protection.
Hardware Safeguards & RJ11/RJ45 Line Surge Defense
Built-in hardware safeguards against output overloads, output short circuits, battery undervoltage, and thermal spikes. Features dedicated RJ11/RJ45 surge protection ports to shield network modems, telecom lines, and Ethernet switches from lightning strikes and transient voltage spikes.
Interactive LCD Visualizer, Mute Function & RS232/USB Monitoring
Features a clear graphical LCD display providing real-time telemetry on AC input/output voltage, load percentage, battery capacity bar, and operating modes. Includes a silence setup button to mute buzzer alarms, alongside optional RS232 / USB ports for smart network monitoring.
