DC/DC Converter URB1D_LD-15W & URB1D_LD-20W Series 15W&20W,Ultra wide input isolated & regulated DC/DC converter Wide input voltage range (4:1) High efficiency up to 89% Isolation voltage :1.5K VDC Operating temperature range: -40℃ to +85℃ 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-20W series Wide input voltage range is 40-160VDC. It is suitable for 72 V, 96 V, 110 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 EN60950 standards. All models are particularly suited to railway etc. Selection Guide Efficiency (%,Min/Typ.) @ Full Load Nominal (Range) Output Output Voltage (VDC) 3.3 Output Current (mA)(Max./Min.) Note: ①Series 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; ②Absolute maximum rating without damage on the converter, but it isn't recommended; ③The 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 Input Current (full load / no-load) Operating Conditions Reflected Ripple Current Input impulse Voltage (1sec. max.)
