Product details
In thermal power plant DCS control systems and substation dispatch communication systems, even millisecond power interruptions can trigger major accidents. With 35 years of industry expertise, Santak's power-dedicated UPS SPU series is engineered to address unique power sector demands: its DC bus direct-connection technology integrates directly with the plant's 220V DC panel, eliminating the need for additional battery banks—cutting 50% of maintenance costs while avoiding battery aging risks. During grid flickers, the device instantly switches to DC power, coupled with ultra-precise AC220V±1% stabilized output, ensuring continuous stable operation for critical equipment like DEH electro-hydraulic control systems.Designed for high-dust and strong EMI environments in substations, the SPU series meets DL/T1074-2019 EMC standards, operating continuously at -25°C to 55°C with 95% humidity. Its anti-corrosion coating and seismic structure easily withstand harsh substation conditions. For power system nonlinear load impacts, it features intelligent waveform correction technology, maintaining THD≤3% pure sine wave output even with IT device switching power supplies or motor start/stop distortions.Test data shows the SPU series maintains ≥83% energy conversion efficiency under extreme ±25% grid voltage fluctuations. Combined with overload bypass transfer, short-circuit current limiting, and other multi-protection mechanisms, it ensures 365-day zero-downtime protection for critical power equipment.Product Parameters
