Three-phase UPS ARIET HD3380H

Online UPS with three-phase input and three-phase output (3:3), which uses a reliable circuit with a thyristor phase-controlled rectifier and an IGBT inverter, ensuring a high level of reliability and operating stability, while the built-in isolation transformer further enhances system safety and robustness. Online system with fully digital control based on a dual-processor DSP, three-phase input and output, isolation transformer, and zero transfer time, ensuring stable operation with the grid, batteries, and diesel generators ADVANTAGES Fully digital architecture based on a dual-processor DSP chip provides advanced control, precise logic with zero drift, and easy updating, debugging, and maintenance. A highly reliable topology with a thyristor phase-controlled rectifier, IGBT inverter, and isolation transformer enhances system safety, impact resistance, and electrical isolation. Direct battery connection to the bus guarantees zero transfer time between mains and battery modes, while the static switch provides instantaneous (0 ms) transfer 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 capacity. 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 combining up to six UPS units and ensures high system fault tolerance during main power grid outages. Extended monitoring and protection functions, including RS232/RS485 interfaces, an LCD display, and a full set of electrical protections, ensure status monitoring, event logging, and safe UPS operation.
