DGA890 80KVA 500KVA

DGA890 80KVA 500KVA

High-Reliability Transformer-Based On-Line UPS

The DG890Series (80 kVA – 500 kVA) UPS acquires online double conversion with full DSP technology. Its rectifier adopts three-level PWM rectifier technology based on IGBT components, achieving a high input power factor and low input harmonic current. Its inverter also adopts PWM technology based on IGBT components and is equipped with an output isolation transformer, achieving high performance with stable voltage and frequency, low waveform distortion, strong load capacity and impact resistance capacity. The DG890 Series maintains a high efficiency output factor to 0.9, offering high quality power for loads including inductive or capacitive loads in industrial applications.
