Santak SPU 12kVA Power-Specific Uninterruptible UPS Power Supply 12kVA

Product details

Santak SPU 12kVA Power-Specific UPS adopts a dual-isolation architecture design, meeting the stringent requirements of power systems for power supply reliability. The device directly connects to the DC power system (110/220VDC) of power plants/substations, effectively preventing reverse current through check diodes, reducing battery investment and maintenance costs. The input side supports three-phase 380V±25% or single-phase 220V±25% voltage fluctuations, with output waveform distortion below 3% and efficiency over 83%, capable of handling complex power demands of IT equipment, nonlinear loads, and impact loads.Built-in multi-protection mechanisms include automatic shutdown for low battery voltage, overload bypass switching, short-circuit current limiting, etc. With EMC filters, it is certified by EN50091-2, ensuring stable operation in wide-temperature environments from -15°C to 55°C. Widely applicable in scenarios like booster stations and dispatch communication systems, providing comprehensive power protection compliant with industry standards for the power sector.
