SKE SKGH Series 1K–10KVA Industrial Online UPS | True Online Double Conversion, Isolation Transformer, Wide Input, Pure Sine Wave for Harsh Industrial Environments
Product Overview
The SKE SKGH Series (1K–10KVA) is a heavy-duty, low-frequency industrial online UPS designed for the harshest operating environments. Utilizing true online double-conversion (AC-DC-AC) technology and a built-in output isolation transformer, it provides galvanic isolation, suppresses power surges/spikes, and eliminates grid disturbances—delivering continuous, regulated power for mission-critical industrial loads. Its industrial-grade design, wide input tolerance, and strong load adaptability make it the ideal power protection solution for factories, manufacturing lines, industrial automation, and rugged outdoor applications.
