Three-phase UPS ARIET HD33120H

The ARIET HD33120H online UPS with three-phase input and three-phase output (3:3) uses a reliable circuit with a thyristor phase-controlled rectifier and an IGBT inverter, ensuring a high level of reliability and stability of operation, while the built-in isolation transformer further enhances the safety and resilience of the system. An online system with fully digital control based on a dual-processor DSP, three-phase input and output, an isolation transformer, and zero transfer time, ensuring stable operation with the grid, batteries, and diesel generators ADVANTAGES A fully digital architecture based on a dual-processor DSP chip provides advanced control, precise logic with no zero drift, and convenient updating, debugging, and maintenance. A highly reliable topology with a thyristor phase-controlled rectifier, IGBT inverter, and isolation transformer improves the safety, surge withstand capability, and electrical isolation of the system. Direct battery connection to the bus guarantees zero transfer time between mains and battery modes, while the static switch provides instantaneous (0 ms) switching between the inverter and bypass. Input and output characteristics allow operation with various voltage and frequency standards (380/400/415 V, 50/60 Hz), providing a high output power factor and excellent overload capability. The POWER WALK IN function ensures smooth operation with diesel generators, prevents startup problems, and optimizes power distribution between the generator and the battery. The intelligent battery management system automatically switches charging modes, predicts discharge time, and performs self-diagnostics to extend battery life. Support for parallel operation in an N+X configuration with automatic redundancy allows up to six UPS units to be combined and ensures high system fault tolerance during mains power outages. Advanced monitoring and protection functions, including RS232/RS485 interfaces, an LCD display, and a full set of electrical protections, provide status monitoring, event logging, and safe UPS operation.
