  • 200W Toroidal Isolation Transformer

    Toroidal isolation transformer: Safety -- the secondary of the isolation transformer is not connected with the earth, and the toroidal isolation transformer's output is "floating ground". When people touch any line of the secondary of the isolation transformer, they will not get electric shock because they cannot form a current loop. Prevent power electronic devices from polluting the power grid - transformers have a great attenuation effect on high-frequency harmonics, so power electronic devices can avoid polluting the power grid.

  • 120W Toroidal Power Audio Isolation Transformer

    Toroidal isolation transformer: Safety -- the secondary of the isolation transformer is not connected with the earth, and the toroidal isolation transformer's output is "floating ground".

  • Single-Phase Isolation Low-Frequency Toroidal Transformer

    The Features of Single-Phase Isolation Low-Frequency Toroidal Transformer: (1) High efficiency. -It is product by high quality material and the type is compact. It can narrow the gap between the coil and the core. So the efficiency is above 95% (2) Low magnetic flux leakage. -The gap between core and coil is small and the coil is unformly. (3) Low noise and low temperature. -Due to the high quality material and the coil is unformly, the resistance loss and the fever is very low.
