Santak SPU 1kVA Power-Specific Uninterruptible UPS Power Supply 1kVA

Product details

Santak SPU 1kVA Power-Specific UPS, built on over 30 years of technical expertise, is tailored for critical loads in power systems, complying with industry standards such as "DL/T 5491-2014" and "DL/T 1074-2019", ensuring power supply continuity in scenarios like power plants and substations. The product features a DC bus input design, directly connecting to the power system's DC power supply (110V/220V) without additional charging devices, significantly reducing battery investment and maintenance costs. Its dual isolation technology effectively isolates the grid from loads, preventing power disturbances like surges and impacts, ensuring the safe operation of high-precision equipment such as DCS, DEH, and microcomputer monitoring systems.The SPU series supports wide voltage input (AC 220V±25%, DC 180V-270V/90V-135V), adapting to power environment fluctuations, with output precision up to AC220V±1% and low waveform distortion, meeting the stringent demands of IT equipment and nonlinear loads. Built-in multiple protection mechanisms, including overload bypass transfer, short-circuit current limiting, and automatic shutdown for low battery voltage, combined with a high conversion efficiency of ≥83%, ensure long-term stable operation in harsh physical environments (high dust, corrosion, vibration).Typically applied in booster stations, industrial control systems, and step-down substations, covering capacity requirements of 3-20kVA, it serves as the core power protection solution for power generation groups, grid companies, and enterprise users.
