Specifications subject to change without notice.
5ACA_4 Series
5W- Single Output AC-DC Converter - Universal Input - Isolated & Regulated
Efficiency
5ACA_24S4
5ACA_12S4
5ACA_05S4
Note:
Output filtering capacitor C2 is a electrolytic capacitor, it is recommended to use high frequency
and low impedance electrolytic capacitors. For capacitance and current of capacitor please
refer to manufacture’s datasheet. Output capacitor withstand voltage derating should be 80% or
above. C1 is ceramic capacitor, which is used to filter high-frequency noise. External input NTC
is recommended to use 12D-5; External input MOV is recommended to use S14K350.
Note:
Suggestions for safety regulation and wiring width: wire width ≥3mm, distance between wires
≥6mm, and distance between wire and ground ≥6mm.
