SNAU4433 Summary
The on-board switch oscillation and voltage stabilization feedback circuit of SNAU4433 is often damaged by the inability of the frequency converter to power on, the failure of the indicator light, and the reporting of low voltage faults. Belonging to the core maintenance spare parts of discontinued models, it is necessary to check the peripheral circuits before replacement to avoid secondary damage and ensure the stable operation of transmission equipment.
