The E_S-1W series is an upgrade to the A_S-1W series. The input-output isolation voltage has been increased to 3000V, and the terminal pin configuration has changed, while all other specifications remain unchanged.
The voltage ratio suitable for input power supply is relatively stable, and the input and output require isolation In situations where voltage stability is not a high requirement. For example: pure digital circuits, general low-frequency modes Analog circuits, relay drive circuits, data exchange circuits, etc.
