6 / 6 page The copyright and authority for the interpretation of the products are reserved by MORNSUN URA_YMD-6WR2 & URB_YMD-6WR2 2013.12.02-B/0 Page 6 of 6 Special Package Series(A2S/A4S) TEST CONFIGURATIONS Input Reflected-Ripple Current Test Setup Input reflected-ripple current is measured with an inductor Lin and Capacitor Cin to simulate the source impedance. DC Cin Lin DC Load Oscilloscope Current Probe Lin(4.7 µH) Cin(220 µF, ESR < 1.0Ω at 100 KHz) DESIGN CONSIDERATIONS 1) Recommended circuit All the URA_YMD-6WR2 & URB_YMD-6WR2 Series have been tested according to the following recommended test circuit before leaving the factory (see Figure 5). If you want to further decrease the input/output ripple, you can increase a capacitance-values properly or choose capacitors with low ESR, but the total capacitance of the filter capacitor must not exceed the Max. Capacitive Load. Cin: 100 μF(Vin nom=24V) Cin: 10 μF~47μF(Vin nom=48V) Cout: 10 μF Vin GND +Vo 0V DC Cin DC Cout Cout -Vo Dua l Sing le Vin GND +Vo 0V DC Cin DC Cout (Figure 5) 2) It is not recommended to increase the output power capability by connecting two or more converters in parallel.The product is not hot-swappable Note: 1. Min. load shouldn't be less than 5%, otherwise ripple maybe increased dramatically, If the product operates under min. load, it may not be guaranteed to meet all specifications listed. Operation under minimum load will not damage the converter. 2. Recommended Dual output models unbalanced load is ≤±5%, If the product operates>±5%, it may not be guaranteed to meet all specifications listed. Please contact our technical support for more details. 3. Max. Capacitive Load is tested at input voltage range and full load. 4. All specifications measured at Ta=25 °C, humidity<75%, nominal input voltage and rated output load unless otherwise specified. 5. In this datasheet, all test methods are based on our corporate standards. 6. All characteristics are for listed models, and non-standard models may perform differently. Please contact our technical support for more details. 7. Please contact our technical support for any specific requirement. 8. Specifications of this product are subject to changes without prior notice. MORNSUN Science & Technology Co.,Ltd.
