Santak SPU 15kVA Power-Specific Uninterruptible UPS Power Supply 15kVA

Product details

Santak SPU 15kVA Power-Specific UPS, built on over 30 years of industry expertise, is tailored for critical loads in power systems. The product meets DL/T5491-2014 and DL/T1074-2019 power industry standards, adopting a direct DC bus input design for seamless integration with 110V or 220V DC power systems in power plants/substations—eliminating the need for additional charging modules and significantly reducing battery investment and maintenance costs. Its dual-isolation architecture physically separates the grid from loads, effectively suppressing surges and electromagnetic interference, ensuring pure power supply for precision control systems like DCS and DEH.Facing harsh environments such as high dust, corrosive gases, a wide temperature range of -25°C to 55°C, and 85% humidity, the SPU series ensures stable operation under extreme conditions like vibration, humidity, and heat through reinforced structural design and component selection. The product supports IT equipment, nonlinear loads, and instantaneous impact loads (e.g., motor start-stop), with output waveform distortion below 3% and overload capacity of 125% for 30 minutes, meeting stringent power quality requirements for scenarios like power dispatch communication and microcomputer monitoring. Built-in multi-layer protection mechanisms include automatic shutdown for low battery voltage, short-circuit current limiting, and intelligent fault bypass switching, providing "zero interruption" power security for power systems around the clock.
