The TT020B Long Machine model UPS is a 20kVA three-phase uninterruptible power supply (UPS) designed for high performance and reliability. It operates on an input voltage of 380/400/415VAC with a frequency range of 50/60Hz and provides excellent power factor (>0.99) with minimal current distortion (THDi < 3% under 100% linear load). The voltage range is 304-478VAC under full load, and from 304-228VAC, the load is linearly derated from 100% to 50%. The system supports a battery voltage of ±240VDC with adjustable sections (30-50), and it features a charging power of up to 20% of active power with high precision (±1%). This UPS is ideal for environments requiring stable, continuous power supply with low maintenance and efficient energy usage.
