SKE SC Series 10K–20KVA High-Frequency Online UPS | True Online Double Conversion, 0ms Transfer, 3/1-Phase, Pure Sine Wave for Data Centers & Industrial Critical Loads
Product Overview
The SKE SC Series (10K–20KVA) is a fully digital, high-frequency online UPS engineered for medium-to-large critical loads. Utilizing true online double-conversion (AC-DC-AC) technology, it continuously conditions incoming power to deliver perfect, regulated AC power—completely isolating connected equipment from all grid disturbances. With a 3-phase input / 1-phase output design, high power density, and industrial-grade durability, the SC Series is the optimal power protection solution for data centers, industrial control rooms, medical facilities, telecommunications, and commercial infrastructure.
Key Features & Benefits
True Online Double Conversion: 0ms transfer time; seamless switchover eliminates downtime and data loss risks.
DSP Digital Control: High precision, fast response, and stable performance under all grid conditions.
3-Phase Input / 1-Phase Output: Wide input voltage (208–478VAC) & frequency (40–70Hz) range; adapts to unstable grids.
High Efficiency & Energy Saving: Up to 95% efficiency (online mode); ECO mode (98%) cuts power costs.
Active PFC Technology: Input power factor ≥0.99, low THD (<3%), reduces grid pollution.
Output Power Factor 1.0: Strong load adaptability; supports servers, motors, and non-linear loads.
Pure Sine Wave Output: Low distortion (<3% linear load); compatible with all sensitive electronics.
