2、 Over-zero protection: 0.2 VAC
Synchronous High-frequency Modulation
In the process of the grid, usually adapt the same phase angle in parallel. (ie, When the two-phase alternating
current total is equal to 0.Use switch to combination the two AC fusion) and the product is rectified AC
half-frequency AC to 100Hz first, then the machine use the high frequency current in the circuit and
semi-100Hz frequency alternating current generated combination, to achieve high-frequency modulation.
