Designed in the 10kVA to 600kVA range, this three-phase transformer-equipped UPS ensures stable voltage output even during grid fluctuations, making it ideal for mission-critical applications worldwide. Key Features: - Digital double conversion topology with integrated isolation transformer for superior waveform purity - High-efficiency IGBT-based power stage and static switch for enhanced reliability and reduced heat generation - Microprocessor-controlled system using MCU and CPLD for precise regulation and real-time diagnostics - Compatibility with both lead-acid and lithium iron phosphate (LiFePO4) battery technologies - Advanced EMI/RFI filtering to protect sensitive equipment from electrical noise and surges - Wide input voltage tolerance and robust surge protection for operation in unstable grid conditions Detailed Description: The CHP3000 series represents a significant leap beyond traditional analog-based UPS systems. By leveraging modern SMD (Surface Mount Device) assembly techniques and sixth-generation IGBTs, this unit delivers exceptional stability, minimal harmonic distortion, and extended service life. Its fully digital architecture allows intelligent load management, automatic self-testing, and remote monitoring capabilities—ensuring that your critical infrastructure remains operational regardless of external power disruptions. With built-in redundancy features and modular design principles, these units are suitable for continuous 24/7 operations across diverse global markets. Ideal Applications: This low-frequency three-phase online UPS serves as an essential component in telecom data centers, financial institutions (ATMs, trading floors), transportation hubs, utility substations, manufacturing plants, and healthcare facilities where uninterrupted power delivery is non-negotiable. Whether deployed in a standalone configuration or as part of a larger power redundancy network, it provides peace of mind by maintaining clean sine wave output under all operating conditions—from brownouts to blackouts. User Feedback: Users consistently praise its quiet operation, rapid response time, and long-term reliability. Many highlight how it has prevented costly downtime in server rooms and automated production lines. The intuitive interface and comprehensive status reporting make maintenance straightforward, while the inclusion of smart battery management systems extends battery lifespan significantly compared to older models. Frequently Asked Questions: What makes this UPS different from standard models? It uses digital signal processing instead of analog circuits, enabling more accurate control, faster fault detection, and better adaptability to varying grid quality around the world. Can it support both lead-acid and LiFePO4 batteries? Yes, the system is designed to work seamlessly with either battery type, allowing users to choose based on cost, lifespan, or environmental considerations. Is it suitable for international use? Absolutely—it meets global standards for electromagnetic compatibility (EMC), safety certification (like CE and UL), and operates reliably in regions with inconsistent utility power. How does the transformer improve performance? The output isolation transformer eliminates ground loops, reduces electrical noise, and stabilizes voltage levels, ensuring cleaner power to connected loads such as servers, medical devices, or CNC machinery.
