SUNGJIN TRANSFORMER

Using grain-oriented electrical steel and PHD-core as the silicone sheet of cast resin transformer and improving winding method, it optimizes total loss(no-load loss plus load loss) and significantly decreases noise - namely, it is low-noise and high efficient popular breitling avenger replica transformer.

No-load loss reduction

Reduced standby power with more than 50 percent decrease of no-load loss against standard transformers by using grain-oriented electrical steel and PHD-core as the silicone sheet.

Load loss reduction

More than 20 percent decrease of load loss by optimal winding design.

Low noise 

Improved noise to decrease over 7 to 11dB compared with KS standard.

By applying grain-oriented electrical steel and a PHD core, along with an optimized winding design, our cast resin transformers minimize total losses (no-load and load losses) while significantly reducing noise, ensuring high efficiency and low-noise performance.

No-Load Loss Reduction

Standby power consumption is reduced by more than 50% compared to standard transformers through the use of grain-oriented electrical steel and a PHD core.

Load Loss Reduction

Load losses are reduced by over 20% through optimized winding design.

Low Noise

Noise levels are reduced by approximately 7 to 11 dB compared to KS standards.
