DC/DC ConverterURB1 D_LD-15W & URB1 D_LD-20W Series 15W & 20W, Ultra wide input isolated & regulated DC/DC converter C€ Patent Protection RoHS FEATURES • Ultra wide input voltage range (4:1) • High efficiency up to 89% • Isolation voltage : 1.5K VDC • Operating temperature range: -40°C to +85°C • Output short circuit(automatic recovery), over-current, over-voltage protection • Six-sided metal shielding package • International standard pin-out • Reverse voltage protection available with A2S(Chassis mounting) or A4S(35mm DIN-Rail mounting) • EN60950 approval URB1D_LD-15W & URB1D_LD-20Wseries Wide input voltage range is 40-160VDC. it is suitable for 72V, 11VVstandardinput of the bus voltage, single output and 1500VDC isolation, over current, over voltage and short-circuit protection. It offers good EMC performance, meet EN60950standards. All models are particularly suited to railway etc. ® Series with suffix "H" are heat sink mounting; series with suffix "A2S" are chassis mounting, with suffix "A4S" are DIN-Rail mounting, for example URB1D05LD-20WHA2S is chassis mounting of with heat sink, URB1D05LD-20WA4S is DIN-Rail mounting of without heat sink; If the application has a higher requirement for heat dissipation, you can choose modules with heat sink; (2 The minimum input voltage and starting voltage of A2S (wiring) and A4S (rail) Model are 1VDC higher than those of DIP package due to input reverse polarity protection function; (3 Absolute maximum rating without damage on the converter, but it isn't recommended; (4 The efficiency of A2S (wiring type) and A4S (rail type) products is 2% lower than the above-mentioned value due to the reverse connection protection for input.

DC/DC ConverterURB1D LD-15W & URB1D LD-20W 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. 2.
