Product Overview
The YCU Series is a high-performance, Uninterruptible Power System (UPS) designed to provide continuous, high-quality power for critical infrastructure. By integrating advanced energy storage with a high-precision inverter, the system ensures a stable, constant-voltage, and constant-frequency power supply. It is specifically engineered to protect sensitive equipment—such as medical imaging devices, data centers, and industrial automation—against power interruptions, voltage fluctuations, and electrical noise.
Key Features
- 100% Digital Control: Utilizing high-speed 32-bit microcontrollers (MCU/DSP), the system achieves precise real-time monitoring and rapid response to power grid anomalies.
- Advanced IGBT Technology: Equipped with high-performance Integrated Gate Bipolar Transistor (IGBT) power modules, ensuring high efficiency, low heat dissipation, and superior reliability.
- Zero Transfer Time: The online double-conversion architecture guarantees a 0ms switching time between mains and battery power, providing seamless protection for mission-critical loads.
- Superior Load Adaptability: Supports 0% to 100% sudden load changes without reverting to bypass mode, maintaining stable output under complex operating conditions.
- Green Power & High Efficiency: Features a high input power factor (>0.98) and low harmonic distortion (THDi < 3%), minimizing impact on the upstream power grid.
Technical Specifications
