KELONG High-Frequency IGBT Rectifier Models utilize dual conversion online technology. The KR(/B)33 series ensures high-quality power supply for any data processing or industrial load, particularly suitable for protecting critical loads. This series features a new configuration, including IGBT rectifiers that ensure sinusoidal input current, replacing traditional thyristor rectifiers. Additionally, the entire product line is compatible with isolated transformers, ensuring complete electrical isolation of the output, thereby avoiding the impact of grid anomalies on load equipment at the input end.

High reliability
High Reliability
● Advanced dual DSP control technology, rapid data processing
● Features rapid fault self-diagnosis and processing capabilities, comprehensive self-protection functions, and higher reliability
Increase circuit integration, optimize circuit design, enhance anti-interference capability, and ensure greater stability in performance.
Enhanced Total Cost of Ownership
More optimized TCO
● Overall efficiency up to 96%, saving energy consumption (both the UPS's own heat dissipation and air conditioning consumption), reducing operating costs
● The default output power factor is 0.9, offering a higher useful work output at the same price, providing a better cost-performance ratio, and aligning with the trend of increasing power factors in IT products.
More intelligent operation and maintenance management
More intelligent OM
● Large-sized color touch screen design, more ergonomic and aesthetically pleasing, with user-friendly operation
● Dual power button combination, a blend of soft and hard protection; EPO button with protective cover for emergency shutdown, anti-misoperation design, safety upgraded in two aspects
● Rich LCD display and LED indicator display the overall operating status and working parameters, assisted by dynamic topology of energy flow, clear and intuitive
User-friendly interface, close to customer habits, rich in features, easy for information reading and operation
