China Factory for 12 0 12 5amp Transformer - High Frequency Transformer Ferrite Core EPC25 Switching Power Supply Transformer For Doorbells – Sanhe
China Factory for 12 0 12 5amp Transformer - High Frequency Transformer Ferrite Core EPC25 Switching Power Supply Transformer For Doorbells – Sanhe Detail:
Introduction
EPC25 transformer mainly supplies power to each functional module of the doorbell to realize image and sound transmission, data storage, sending control commands and other functions. It can output three sets of voltages at the same time, including power supply and protection. In addition, primary and secondary isolation protection is realized to prevent danger of leakage caused by circuit failures.
