The core of the LKH series toroidal transformer is seamlessly wound from high-quality cold-rolled grain-oriented silicon steel sheets (typically 0.35mm thick), giving it inherent performance advantages over traditional laminated-core transformers.
Coils are uniformly wound around the core, and the magnetic flux lines generated by the coils align almost perfectly with the core's magnetic path. Compared with laminated-core designs, excitation power and core loss are reduced by 25%, bringing a series of key benefits:
Gapless core structureThe core stacking factor can reach over 95%, and the transformer efficiency exceeds 95%. Its no-load current is only 10% of that of an equivalent laminated-core transformer.
Light weight & flexible customizationWith the same core cross-sectional area, a toroidal transformer is lighter than its laminated-core counterpart. The length, width and height of the toroidal core can be freely adjusted to meet customized design requirements.
Low noise, low magnetic leakage & low electromagnetic radiationBenefiting from the gapless core, the transformer produces minimal magnetic leakage and electromagnetic interference. It works with high-sensitivity electronic devices without the need for additional shielding.
Overall, the LKH series toroidal transformer delivers excellent cost performance, reliable output characteristics and strong anti-interference capability, making it a highly competitive electronic transformer solution. It is widely applied in computers, medical equipment, communications systems, instrumentation, audio devices, automatic control systems, quartz lamp lighting and other fields.
