DC/DC ConverterVRA_YMD-6WR3 & VRB_YMD-6WR3 Series Patent Protection RoHS VRA_ YMD-6WR3 & VRB_YMD-6WR3 series are isolated 6W DC-DC products with 2:1 input voltage. The feature efficiency up to 87%, 1500VDC isolation, operating temperature of-40°C to +85°C, input under-voltage protection, output over-voltage, over-current, short circuit protection and EMI meets CISPR22/EN55022 CLASS A, which make them widely applied in medical care, industrial control, electric power, instruments and communication fields. And extension package A2S and A4S also enable them with reverse voltage protection. 6W,wide input, isolated & regulated dual/single output, YMD package, DC-DC converter FEATURES • Wide input voltage range (2:1) • High efficiency up to 87% • No-load power consumption as low as 0.12W • Isolation voltage : 1.5K VDC • Input under-voltage protection, output short circuit, over-current, over-voltage protection • Operating temperature range: -40°C to +85°C • Meet CISPR22/EN55022 CLASS A, without external components • Reverse voltage protection available with A2S(Chassis mounting) or A4S(35mm DIN-Rail mounting) • International standard pin-out • IEC60950, UL60950, EN60950 approval Notes: ® Part No. with suffix of "A2S" means chassis mounting and suffix of "A4S" means DIN-Rail mounting (e.g. VRB2405YMD-6WR3A2S means chassis mounting; VRB2405YMD-6WR3A4S means DIN-Rail mounting); (2 A2S (wiring) and A4S (rail) Model due to input reverse polarity protection function, input voltage range the minimum value and starting voltage is higher than 1VDC DIP package; (2 Absolute maximum rating without damage on the converter, but it isn't recommended; ® Efficiency is measured In nominal input voltage and rated output load;A2S (wiring) and A4S (rail) Model due to input reverse polarity protection, minimum efficiency greater than Min.-2 is qualified; ® The capacitive loads of positive and negative outputs are identical.

DC/DC ConverterVRA_YMD-6WR3 & VRB_YMD-6WR3 SeriesDesign Reference 1. Typical application All the DC/DC converters of this series are tested according to the recommended circuit (see Fig. 2) before delivery. If it is required to further reduce input and output ripple, properly increase the input & output of additional capacitors Cin and Cout or select capacitors of low equivalent impedance provided that the capacitance is no larger than the max. capacitive load of the product. Cins GND°- 3. It is not allowed to connect modules output in parallel to enlarge the power 4. For more information please...
