1-0. General Description The purpose of the document is to specify a Single phase AC input, single output switching power supply. This specification is suitable for: EA10442D Series This product is AC to DC switching power transfer device, it can provide for a 12V, 3.33A max & 40W max DC output with constant voltage source. This Specification defines the input, output, performance characteristics, environment, noise and safety requirement for a power supply. 2‐0. Input Requirements 2‐1.
2‐9. Hold Up Time ≧ 8.3 mSec., @ Normal line, with full load. 2‐10. Rise Time ≦50 mSec.,@ 100‐240VAC input, with full load from 10% to 90% of output voltage. 2‐11. Turn‐ON Time The output voltage should rise to 90% of rated output voltage in less than 3 SEC. from AC apply to 110Vac start up. 3‐0. Output Requirements 3‐1. Output Voltage and Current Output Voltage (Vdc) Current Min.(A) Current Max.(A) +12V 0 3.33A 3‐2. Load Regulation Voltage (Vdc) Tolerance (%) +12V +5/, ‐5 3‐3.
3‐6. Over Current Protection 110%‐200% of rated output current. The adapter will enter protection at overload mode and no damage. It will enter into normal condition if the fault condition is removed. 3‐7.
