DC/DC ConverterURB1 D_LD-15W & URB1 D_LD-20W Series 15W&20W,Ultra wide input isolated & regulated DC/DC converter FEATURES • Wide input voltage range (4:1) • High efficiency up to 89% • Isolation voltage : 1.5K VDC • Operating temperature range: -40C to +85C • 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(DIN-Rail mounting) • EN60950 approval Patent Protection RoHS URB1D_LD-15W& URB1D_LD-20Wseries Wide input voltage range is 40-160VDC. it s suitable for 72 V, 96 V, 10 V standard input of the bus voltage, single output and 1500VDC isolation, over current, over voltage and short-circuit protection. It offers good EMC performance, meet EN60950standards. AH models are particularly suited to railway etc. Note: ©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,URB1 D05LD-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; ©Absolute maximum rating without damage on the converter, but it isn't recommended; ©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; Input Specifications Item MORN5UN GUANGZHOU SCIENCE & TECHNOLOGY CO.,LTD.
