Power Supply Switch Mode Descriptions: These are a series of general purpose AC/DC adapters which convert 100V AC to 240V AC to a stabilized DC voltage of 5V with rated output current of 2,000mA. Please connect the electrical power first and then add the load when using this SMPS. The switching mode power supply meets the requirements of lead free and ROHS. Input Feature: Input Voltage and Frequency The switching mode power supply shall meet all specifications when powered from the following sources. Rating Voltage Line Frequency Minimum Voltage Maximum Voltage 100-240V AC 50/60Hz 90V AC 264V AC Efficiency The minimum efficiency shall be 73.37% under 115V AC/230V AC input and output full load. Input Current The maximum input current shall be less than 0.45A. Input In-rush Current Peak inrush current shall be limited to 50A. Input Leakage Current The leakage current shall not exceed 0.25mA. Output Feature: Output Voltage and Current The switching mode power supply shall have one regulated DC output voltage: 5V DC. The table below defines the total regulation banding for the output, which includes line regulation, load regulation, transient response, and effects due to environmental conditions and aging. Voltage shall be measured at its output connector. Output Output Current Range Output Voltage Range Ripple & Noise Min Max Min Max Max. 5V 0A 2A 4.75V 5.25V 150m Vpp Ripple & Noise Test: Add 0.1uF/50V ceramic capacitor and 10uF/50V aluminum electrolytic capacitor across the output terminal. Measured with 20MHz Bandwidth Oscilloscope. Dynamic Response The load current of the output is changed between 25% and 75% under full load at 0.5A/ms the excursion of the output shall not exceed 10% of the nominal output voltage. The output voltage shall be within 10% of the steady state voltage in 1ms. Startup and Turn-on Delay The switching mode power supply shall be able to start up into a resistive load up to the maximum rated current with maximum load capacitance of 1,000uF. The elapsed time between the application of input power and the attainment of output voltage to the nominal value shall not exceed 3 seconds. www.element14.com www.farnell.com www.newark.com www.cpc.co.uk Page <1> 08/12/14 V1.0Power Supply Switch Mode Protection Feature: Over Current Protection The switching mode power supply shall withstand a continuous over current without damage. It may be applied before power- up, or after power-up. The switching mode power supply shall perform normally again after the over current is removed. Short Circuit Protection Short circuit will not cause the switching mode power supply to damage, or any safety hazards. It shall perform normally again after the short circuit is removed. Safety Standards: Safety The switching mode power supply has approved by the following safety standards: *UL60950 EN 60950 Dielectric Strength (HI-POT) Input to Output Terminal : 4,242V DC 3Sec 5mA. Input to Case : 4,242V DC 3Sec 5mA. When DC voltage of 4.24KV is applied, and the voltage applied to the insulation under test, it gradually rises from zero to the prescribed voltage in 1s, and holds at the value for 3s between the input and output, and between the input and housing, the current sensitivity shall be less than 5mA, after the test, the switching mode power supply shall exhibit no electrical and mechanical abnormalities. Reliability: Burn-in The burn-in test will be performed at least 3 hours at 25 degrees centigrade under full load. MTBF When the operation is complying with this specification, the MTBF of switching mode power supply will be 25K hours at 25C.
