To receive grid power and apply an appropriate voltage to the load, the system uses a reactor-type transformer. Because it is designed with sufficient overload capacity, it generates very little heat during operation. According to KERI test results, even when operated at 130% overload for more than four hours, the reactor’s temperature rise was only about 20–40°C. Considering the allowable limit (80°C), this indicates a highly stable product. The toroidal core—one of the key components of this product—has a donut-shaped structure with no core joints, resulting in low core loss and extremely low magnetizing current. Because the required core cross-sectional area is smaller, the winding length is shorter. This allows a larger conductor cross-section and naturally reduces copper loss in the coil. The reactor consists of a voltage coil and a current coil. The voltage coil carries only magnetizing current, so copper loss is minimal. The current coil has about 10% of the total turns and carries the load current; its capacity is only about 10% of the rated value, resulting in very low load loss and exceptionally high efficiency.
As a result, our solution is not limited to dedicated loads (lighting-only or motor-only). It is well suited for mixed loads that include both lighting and motors. Unlike cut-core transformers, the reactor used in our system is wound on a toroidal core, providing a structure that does not loosen or deform even under severe mechanical or electrical stress. With cut-core or EI-core designs, interaction between the primary and secondary coils can ultimately lead to transformer failure. Our design minimizes such primary–secondary reactive forces. Motor starting current can reach 5–8 times the rated current, with a starting time of up to 15 seconds under harsh conditions. The reactor used in our system is designed to withstand these conditions reliably.
When power is applied through this product or when switching via BYPASS (direct → save, save → direct), the circuit does not open. An internal circuit minimizes inrush current, helping eliminate complex transient events such as surges.
Reactor and PCB components are carefully selected only after completing rigorous tests. Finished assemblies then undergo selective load testing during production, followed by an additional period of in-factory verification before shipment. We maintain a strict quality-first inspection process and keep traceability records for each product to support future service and maintenance. (CE Mark certified)
This product is built with extensive protection circuitry to prevent power outages under all
conditions and to ensure stable operation even in harsh electrical environments.
If an operating fault occurs or an abnormal load condition is detected, the built-in alarm system
activates and the unit automatically switches to Safe Mode to maintain continuous power supply.
automatic switching is not available, the system can be manually switched to direct grid power
with a simple switch operation.
Energy-saving awareness is widespread in the U.S., Japan, and Europe. Because big
efficiency gains from individual devices are limited, governments promote power-saving
technologies and adoption.
Equipment value is no longer judged only by price and electricity cost. Environmental impact,
pollution reduction, and carbon regulations are increasingly considered. As carbon costs rise,
pricing will shift toward efficiency and environmental performance, not just materials and labor.
