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: EA1019KHES Series This product is AC to DC switching power transfer device, it can provide for an 24V, 1.0A max &24W 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. Input Electrical Specification 2-1.
2-7. Inrush Current ≦ 40A at 115 Vac ≦ 80A at 230 Vac At cold start, maximum load. 2-8. Line Regulation This line regulation is less than ± 1%, of rated output voltage @ full load. 2-9. Hold Up Time ≧ 8.3mSec., @ Normal line, with full load. 2-10. Rise Time ≦50mSec., @ Rated AC 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 100Vac from start up. 3-0. Output Requirements 3-1.
Output Ripple/Noise +24V Vp-p ≦240mV Ripple / Noise: 60Hz ripple + switching ripple and noise Ripple & Noise are measured at the end of output cable which are added a 0.1uF ceramic capacitor and a 47uF electrolytic capacitor 3-5. Over Load Protection 180% max of rated output current. The adapter can withstand continuous short at DC output and no damage. It will enter into normal condition if the fault condition is removed. 3-6.
