Santak SPU 3kVA Power-Specific Uninterruptible UPS Power Supply 3kVA

Product details

In power plant step-up stations and substation dispatch systems, the Santak SPU series power-specific UPS safeguards core power systems with professional-grade protection. Developed based on Santak's 30+ years of power industry experience, it complies with both DL/T5491-2014 and DL/T1074-2019 standards. Its innovative DC bus direct-connection design saves 40% battery investment, while the reverse-blocking diode on DC input effectively prevents current backflow. Supporting 220V±25% wide voltage input range with <3% output waveform distortion, it ensures stable operation of sensitive equipment like microcomputer monitoring and dispatch communication systems even in extreme conditions (-25°C to 55°C and 95% humidity).For power industry-specific impulsive loads and surge interference, the SPU 3kVA adopts full digital control technology, achieving seamless backup power switching within 0.1 seconds. With 0.8 output power factor and optimized crest factor design, it perfectly matches nonlinear load requirements like DCS/DEH systems. The built-in intelligent fault diagnosis system automatically switches to bypass at 130% overload and restores inverter power within 2 seconds after normalization. Its electromagnetic compatibility meets stringent DL/T 1074-2019 certification, delivering 24/7 uninterruptible power solutions for the power sector.
