Product Overview
The Feixiangda T3000 Series 300KVA three phase industrial frequency online UPS is a high-power uninterruptible power system engineered for mission-critical industrial loads. Built on an Online Double Conversion topology, incoming utility power is rectified to DC to float-charge the battery bank, then inverted back to clean, stable sine-wave AC — achieving complete electrical isolation between output and input while suppressing grid harmonics, surges and voltage fluctuations. Control is handled by a high-speed DSP digital chip with ASIC DDC technology, paired with high-power IGBT rectifier and SCR inverter devices, delivering high precision, fast response and rock-solid stability. A built-in output isolation transformer reduces load harmonic current and grid interference, protecting downstream precision equipment.
Key Technical Specifications
Rated capacity 300KVA / 240KW; three-phase input / three-phase output (3P+N+G); input voltage 380VAC ±25%, frequency 50/60Hz ±10%; bypass voltage 380VAC ±15%; inverter/bypass transfer time 0ms (synchronous), <4ms (out-of-sync); output voltage stability ±1% (steady state); pure sine wave output with THD <2% (linear load) and <4% (non-linear load); overall efficiency ≥93%, up to 98% in ECO mode; overload capacity: transfer to bypass after 10 min overload, or 1 min at 125% / 150%.
Key Features
· Dual Static Switch Zero-Transfer Technology: 12 SCRs each on the inverter and bypass sides enable dual non-contact static switching — 0ms synchronous transfer with continuous, smooth output waveform.
Typical Applications
Data centers and telecom rooms; precision medical imaging equipment such as 3.0T MRI; industrial automation lines and robotic arms; CNC / SMT precision equipment; financial and transportation information systems; military facilities; intelligent warehousing and quality inspection equipment.
