model selection guide www.micropowerdirect.com notes: 1. cross regulation is measured with the output being tested at 100% load while the other output is varied from 25% to 100% load. 2. see the typical connection circuit on page three for typical external ltering components. for help with a speci c model or layout issue, contact the factory. 3. isolation voltage is speci ed for input to output. on units with the optional metal case, the isolation voltage for input - case and output - case is 1,000 vdc. 4. operation at no-load will not damage the unit, but they may not meet all speci cations. to meet all speci cations, a minimum load of 33% should be maintained. 5. 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 ma124s-05rui-xx 24 9.0 - 36.0 91.0 20 5.0 300.0 100.0 68 35.0 2,200 200 ma124s-09rui-xx 24 9.0 - 36.0 89.0 20 9.0 167.0 55.7 70 35.0 470 200 ma124s-12rui-xx 24 9.0 - 36.0 86.0 20 12.0 125.0 41.7 72 35.0 470 200 ma124s-15rui-xx 24 9.0 - 36.0 86.0 20 15.0 100.0 33.3 72 35.0 470 200 ma124s-24rui-xx 24 9.0 - 36.0 88.0 30 24.0 62.5 20.8 71 35.0 220 200 ma124d-05rui-xx 24 9.0 - 36.0 94.0 20 ?.0 ?50.0 ?0.0 66 35.0 ?,000 200 ma124d-09rui-xx 24 9.0 - 36.0 91.0 20 ?.0 ?3.3 ?7.8 68 35.0 ?20 200 ma124d-12rui-xx 24 9.0 - 36.0 89.0 20 ?2.0 ?2.5 ?0.8 70 35.0 ?20 200 ma124d-15rui-xx 24 9.0 - 36.0 89.0 20 ?5.0 ?0.0 ?6.7 70 35.0 ?20 200 ma124d-24rui-xx 24 9.0 - 36.0 90.0 30 ?4.0 ?1.0 ?0.3 69 35.0 ?00 200 ma148s-05rui-xx 48 18.0 - 72.0 44.0 10 5.0 300.0 100.0 70 35.0 2,200 100 ma148s-09rui-xx 48 18.0 - 72.0 43.0 10 9.0 167.0 55.7 72 35.0 470 100 ma148s-12rui-xx 48 18.0 - 72.0 42.0 10 12.0 125.0 41.7 74 35.0 470 100 ma148s-15rui-xx 48 18.0 - 72.0 42.0 10 15.0 100.0 33.3 74 35.0 470 100 ma148s-24rui-xx 48 18.0 - 72.0 43.0 10 24.0 62.5 20.8 72 35.0 220 100 ma148d-05rui-xx 48 18.0 - 72.0 45.0 10 ?.0 ?50.0 ?0.0 68 35.0 ?,000 100 ma148d-09rui-xx 48 18.0 - 72.0 44.0 10 ?.0 ?3.3 ?7.8 70 35.0 ?20 100 ma148d-12rui-xx 48 18.0 - 72.0 43.0 10 ?2.0 ?2.5 ?0.8 72 35.0 ?20 100 ma148d-15rui-xx 48 18.0 - 72.0 43.0 10 ?5.0 ?0.0 ?6.7 72 35.0 ?20 100 ma148d-24rui-xx 48 18.0 - 72.0 44.0 10 ?4.0 ?1.0 ?0.3 71 35.0 ?00 100 292 page street ste d stoughton, ma 02072 tel: (781) 344-8226 fax: (781) 344-8481 e-mail: sales@micropowerdirect.com model number for the alternate pin-out (see page 4) , add suf x ?2?to model number (i.e. ma124s-05rui-p2) series power input range isolation ma100x-xxrw 1w 2:1 1.5 kvdc ma100x-xxrwi 1w 2:1 3.5 kvdc ma100x-xxru 1w 4:1 1.5 kvdc ma100x-xxrui 1w 4:1 3.5 kvdc ma200x-xxrw 2w 2:1 1.5 kvdc ma200x-xxrwi 2w 2:1 3.5 kvdc ma200x-xxru 2w 4:1 1.5 kvdc ma200x-xxrui 2w 4:1 3.5 kvdc ma300x-xxrw 3w 2:1 1.5 kvdc ma300x-xxrwi 3w 2:1 3.0 kvdc ma300x-xxru 3w 4:1 1.5 kvdc ma300x-xxrui 3w 4:1 3.0 kvdc ma400x-xxrw 4w 2:1 1.5 kvdc ma400x-xxrwi 4w 2:1 3.5 kvdc ma400x-xxru 4w 4:1 1.5 kvdc ma400x-xxrui 4w 4:1 3.5 kvdc ma500x-xxrw 5w 2:1 1.5 kvdc ma500x-xxrwi 5w 2:1 3.5 kvdc ma500x-xxru 5w 4:1 1.5 kvdc ma500x-xxrui 5w 4:1 3.5 kvdc ma600x-xxrw 6w 2:1 1.5 kvdc ma600x-xxrwi 6w 2:1 3.0 kvdc ma600x-xxru 6w 4:1 1.5 kvdc ma600x-xxrui 6w 4:1 3.0 kvdc new dip dc/dc converter visit our website or contact the factory for more information. families from mpd
www.micropowerdirect.com typical connection typical board layout : with external filter components, single output the diagram above illustrates a typical connection of the MA100RUI series for applications that require meeting conducted emc standards. the units do not require external components to operate as speci ed. for applications requiring very low output noise levels, the output ltering capacitors (c 3 is a low esr electrolytic & c 4 is a ceramic) will often be suf cient. care must be taken in choosing output capacitors not to exceed the capacitive load speci cation for the unit. for dual output units, output capacitors should be connected from each output to common. all external components should be mounted as close to the unit as possible. input noise and surge suppression modules are available for a number of mpd dc/dc power supplies. contact the factory for more information. micropower direct 292 page street ste d stoughton, ma 02072 tel: (781) 344-8226 fax: (781) 344-8481 e-mail: sales@micropowerdirect.com typical board layout : with external filter components, dual output the recommended values for components are: component 24 v in 48 v in c 1 220 f/100v 220 f/100v lcm 12 h 12 h c 2 470 pf/4kv mlcc 470 pf/4kv mlcc c 3 100 f 100 f c 4 4.7 - 10 f 4.7 - 10 f
