model selection guide www.micropowerdirect.com notes: 1. when measuring output ripple & noise, it is recommended that an external capacitor (1 f to 10 f) be placed from the +v out to the -v out pins for single output units and from each output to common for dual output models.. 2. transient recovery is measured to within a 1% error band for a load step change of 25%. 3. these units should not be operated with a load under 5% of full load. operation at no-load will not damage the unit, but they may not meet all speci cations. 4. it is recommended that a fuse be used on the input of a power supply for protection. see the model selection table above for the correct rating. model number input output ef? ciency (%, typ) re? ected ripple current (ma typ) capacitive load (f, max) fuse rating slow-blow (ma) voltage (vdc) current (ma) voltage (vdc) current (ma, max) current (ma, min) nominal range full-load no-load ma305s-05erw 5 4.5 - 9.0 811 40 5.0 600 30 74 20.0 4,700 1,600 ma305s-12erw 5 4.5 - 9.0 780 40 12.0 250 12 77 20.0 2,700 1,600 ma305s-15erw 5 4.5 - 9.0 780 40 15.0 200 10 77 20.0 2,200 1,600 ma305d-05erw 5 4.5 - 9.0 790 40 ?.0 ?00 ?5 76 20.0 2,200 1,600 ma305d-12erw 5 4.5 - 9.0 770 40 ?2.0 ?25 ? 78 20.0 1,800 1,600 ma305d-15erw 5 4.5 - 9.0 770 40 ?5.0 ?00 ? 78 20.0 1,000 1,600 ma312s-03erw 12 9.0 - 18.0 338 30 3.3 909 46 74 30.0 4,700 750 ma312s-05erw 12 9.0 - 18.0 309 30 5.0 600 30 81 30.0 4,700 750 ma312s-12erw 12 9.0 - 18.0 302 30 12.0 250 12 83 30.0 2,700 750 ma312s-15erw 12 9.0 - 18.0 305 30 15.0 200 10 82 30.0 2,200 750 ma312s-24erw 12 9.0 - 18.0 302 30 24.0 125 6 83 30.0 1,800 750 ma312d-05erw 12 9.0 - 18.0 309 30 ?.0 ?00 ?5 81 30.0 2,200 750 MA312D-09ERW 12 9.0 - 18.0 298 30 ?.0 ?66 ? 84 30.0 2,000 750 ma312d-12erw 12 9.0 - 18.0 298 30 ?2.0 ?25 ? 84 30.0 1,800 750 ma312d-15erw 12 9.0 - 18.0 295 30 ?5.0 ?00 ? 85 30.0 1,000 750 ma324s-03erw 24 18.0 - 36.0 160 15 3.3 909 46 78 30.0 4,700 300 ma324s-05erw 24 18.0 - 36.0 155 15 5.0 600 30 81 30.0 4,700 300 ma324s-12erw 24 18.0 - 36.0 146 15 12.0 250 12 86 30.0 2,700 300 ma324s-15erw 24 18.0 - 36.0 146 15 15.0 200 10 86 30.0 2,200 300 ma324s-24erw 24 18.0 - 36.0 147 15 24.0 125 6 85 30.0 1,800 300 ma324d-05erw 24 18.0 - 36.0 153 15 ?.0 ?00 ?5 82 30.0 2,200 300 ma324d-12erw 24 18.0 - 36.0 149 15 ?2.0 ?25 ? 84 30.0 1,800 300 ma324d-15erw 24 18.0 - 36.0 149 15 ?5.0 ?00 ? 84 30.0 1,000 300 ma348s-03erw 48 36.0 - 75.0 82 5 3.3 909 46 76 30.0 4,700 150 ma348s-05erw 48 36.0 - 75.0 77 5 5.0 600 30 82 30.0 4,700 150 ma348s-12erw 48 36.0 - 75.0 73 5 12.0 250 12 86 30.0 2,700 150 ma348s-15erw 48 36.0 - 75.0 73 5 15.0 200 10 86 30.0 2,200 150 ma348d-05erw 48 36.0 - 75.0 77 5 ?.0 ?00 ?5 82 30.0 2,200 150 ma348d-12erw 48 36.0 - 75.0 75 5 ?2.0 ?25 ? 84 30.0 1,800 150 ma348d-15erw 48 36.0 - 75.0 74 5 ?5.0 ?00 ? 85 30.0 1,000 150 ef? ciency vs output load : typical 24 vdc input ef? ciency vs input voltage : typical 24 vdc input derating curve 292 page street ste d stoughton, ma 02072 tel: (781) 344-8226 fax: (781) 344-8481 e-mail: sales@micropowerdirect.com
