These products apply to: 1) Where the voltage of the input power supply is fixed (voltage variation 10%); 2) Where isolation is necessary between input and output (isolation voltage =1000VDC); 3) Where the regulation of the output voltage and the output ripple noise are not demanding. Such as: purely digital circuits, ordinary low frequency analog circuits. These products don't apply to: 1) Where the input supply voltage is varied (variation10%), otherwise our company's WRB series is recommended; 2)Where the isolation voltage between input and output is required to be>1000VDC, otherwise our company's F_S(D)-1W Series of products are recommended; 3)he output load's actual power consumption is less than 0.25W, otherwise our company's B_LS(D)-0.25W Series are recommended. 24 21.6~26.4 3.3 5 3.3 5 9 12 15 15 3.3 5 9 12 15 3.3 5 9 12 15 72 73 74 72 74 77 68 79 75 73 75 79 80 76 74 76 80 81 COMMON SPECIFICATIONS Short circuit protection Temperature rise at full load Cooling Operating temperature range Storage temperature range Lead temperature Storage humidity range Case material MTBF 1 second 25C MAX, 15C TYP Free air convection -40C~+85C -55C ~+125C 300C (1.5mm from case for 10 seconds) 95% Plastic (UL94-V0) >3,500,000 hours ISOLATION SPECIFICATIONS Item Isolation voltage Isolation resistance Test conditions Tested for 1 minute Test at 500VDC Min 1000 1000 Typ Max Units VDC M OUTPUT SPECIFICATIONS Item Output power Line regulation Load regulation Output voltage accuracy Temperature drift Output ripple Switching frequency Test conditions For Vin change of 1% 10% to 100% full load See tolerance envelope graph 100% full load 20MHz Bandwidth Full load, nominal input MIN 0.1 10 TYP MAX 1 1.2 15 0.03 75 Units W % % %/C mVp-p KHz MODEL SELECTION B0505LS-1W Rated Power Package Style Output Voltage Input Voltage Product Series 50 100 MORNSUN Science& Technology Ltd.
