Product details

In core power system scenarios, continuous and stable power supply is crucial for production safety and operational efficiency. The Santak SPU 12kVA power-specific UPS utilizes DC bus direct-connection technology, directly drawing power from the DC system, saving 30% in battery investment and reducing maintenance costs in power plants and substations. Its DC input supports dual-voltage modes of DC220V (180-270V) and DC110V (90-135V), with reverse-blocking diodes preventing current backflow. Combined with input-output dual-isolation design, it effectively mitigates grid fluctuations' impact on precision equipment.For critical loads such as power plant DCS control systems and substation dispatch communication systems, this device demonstrates exceptional adaptability: wide-range voltage input (AC220V±25%/380V±25%) handles power fluctuations, while output waveform distortion rate ≤3% ensures stable operation of sensitive equipment. It maintains ≥83% operational efficiency even in wide temperature environments from -10°C to 50°C, with its unique anti-vibration structure and IP42 protection rating enabling reliable performance in high-dust areas of coal-fired power plants or high-salt-fog environments of coastal substations. When facing load surges, the UPS can withstand 125% overload for 10 seconds and automatically switches to bypass, seamlessly reverting to inverter mode once the load stabilizes.The built-in EN50091-2 certified electromagnetic compatibility design, combined with multiple protection mechanisms including output overload, short circuit, and low battery voltage, forms a comprehensive protection system for power automation systems. The device has passed power industry standard certifications such as DL/T5491-2014, successfully ensuring 365-day uninterrupted operation of core systems like microcomputer monitoring and relay protection in scenarios including UHV substations and new energy power stations.
