Shenzhen High-Frequency Single-Line UPS Supplier | Shenzhen High-Frequency Single-Line UPS Wholesale | Shenzhen High-Frequency Single-Line UPS Price [Shenzhen Nuonai Power Supply] Application Fields: Widely used in small and medium-sized machine rooms, financial system small outlets, industrial automation control systems, local network servers, communication servers, Internet cafes, shopping mall cash desks, banks, communication, post, broadcasting and television, public security, transportation, electricity, medical, industrial control, defense, petrochemical, and other important data fields of the national economy. Product Features: - ■ Operation Mode: Dual conversion online design, zero output switching time, and input power factor correction (PFC) technology adopted. - ■ DSP Full Digital Control: Digital control ensures excellent performance indicators and a more stable and reliable control system. - ■ Optimized Battery Group Function Design: Innovative optimization of battery group function design saves more battery usage compared to traditional designs. - ■ Strong Environmental Adaptability: Wide voltage range, input voltage can reach up to 110V under half-load without switching to battery power, input frequency range of 40-70Hz, ensuring stable operation with various fuel generators. - ■ Comprehensive Protection: Features self-diagnosis on startup, timely detection of UPS hidden faults, and integrated multifunctional protection including AC input over/under voltage protection, output overloading/short-circuit protection, inverter overheating protection, battery under-voltage warning protection, and battery overcharge protection. It also has bypass functionality, allowing uninterrupted switching to bypass mode when output overloading or UPS failure occurs, and provides alarm information. It also has input zero-line phase detection function to prevent incorrect zero-line phase connection and has a DC start-up function. - ■ Intelligent Management: Communication RS-232 interface enables multi-functional and multi-purpose monitoring and management operations between UPS and computers through the computer window, including power status and UPS operation monitoring, system settings, menu-driven operation, remote control, self-diagnosis, recording and analysis, and system shutdown operations. It also allows for the selection of SNMP cards to form a network management system. - ■ Adaptation to Chinese Power Grid Environment: Output power factor of 0.8 is suitable for load development trends, achieving stronger loading capacity, with overall efficiency up to 90%, reducing power consumption of UPS, saving user costs. Active power factor correction technology (PFC) is used, with input power factor close to 1, significantly reducing power grid pollution. Designed to meet Chinese power grid requirements, it provides a wide input voltage range, adapts to harsh power grid environments, and an excellent input frequency range allows UPS to adapt to different power supply equipment such as generators.
