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

Product details

With over 30 years of industry experience, the Santak SPU 15kVA power-specific UPS builds a robust power defense for critical loads like DCS control systems in power plants and substation microcomputer monitoring. The device directly connects to the DC power system of power plants, supporting dual-voltage input (DC220V/110V with 180-270V/90-135V wide-range adjustment), eliminating the need for additional charging modules and significantly reducing battery investment and maintenance costs. Facing unique power scenarios with high dust, corrosive gases, and -20°C~55°C wide-temperature environments, its reinforced cabinet structure and IP41 protection rating ensure stable operation under vibration and high-humidity conditions.At its core, the SPU series adopts a dual-isolation design for input and output, effectively isolating grid interference, with output voltage precision reaching AC220V±1% and waveform distortion rate below 3%, perfectly matching the power quality requirements of precision control equipment such as DCS and DEH. In the event of sudden power failure, the device achieves zero-interruption switching through ≥83% high-efficiency energy conversion, sustains 150% overload for 30 seconds and automatically switches to bypass, intelligently restoring when the load returns to normal. Built-in reverse diode prevents current backflow, coupled with EN50091-2 electromagnetic compatibility certification, confidently handling surge impacts and complex load environments.In actual deployment, this model has been widely applied in scenarios such as step-up stations (3-160kVA) of power generation groups, substations (3-20kVA) of grid companies, and step-down stations of enterprises, particularly suitable for hybrid power systems with IT equipment and nonlinear loads. Three-phase 380V±25% wide voltage input capability, paired with a 0.7 output power factor, can simultaneously drive monitoring systems, dispatch communication equipment, and impact loads. When detecting low battery voltage or internal overtemperature, the system automatically executes graded protection and triggers audible and visual alarms, providing multiple safeguards for power safety production.
