model selection guide www.micropowerdirect.com notes: 1. on dual output models, the line regulation for the -v out (pin 16) output is 1.0% max. 2. cross regulation is measured with the +v out (pin 14) set to 50% load and the -v out (pin 16) varied from 10% to 100% load. the load on dual output models should not be unbalanced more than 5%. if the load unbalance is greater than 5%, the unit may not meet all speci cations. 3. 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.. 4. transient recovery is measured to within a 1% error band for a load step change of 25%. 5. short circuit protection is provided by a ?iccup mode circuit. 6. all units are rated for en 55022 (ce/re) class a without external components. they will meet class b with the addition of a discrete lter circuit as shown on page 3. c ontact the factory for more information this circuit or one of our lter/surge suppression modules. 7. to meet the requirements of en 61000-4-4 ( ? kv) external components are needed, as shown on page 3. contact the factory for more information this circuit or one of our lter/ surge suppression modules. 8. to meet the requirements of en 61000-4-5 ( ? kv), external components are needed. this can be done discretely as shown on page 3. c ontact the factory for more information this circuit or one of our lter/surge suppression modules. 9. 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. 10. 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 ma624s-03eru 24 9.0 - 36.0 316 7 3.3 1,500 75 79 20.0 1,800 600 ma624s-05eru 24 9.0 - 36.0 301 7 5.0 1,200 60 83 20.0 1,000 600 ma624s-12eru 24 9.0 - 36.0 287 7 12.0 500 25 87 20.0 100 600 ma624s-15eru 24 9.0 - 36.0 284 7 15.0 400 20 88 20.0 100 600 ma624s-24eru 24 9.0 - 36.0 287 7 24.0 250 12 87 20.0 47 600 ma624d-05eru 24 9.0 - 36.0 301 7 ?.0 ?00 ?0 83 20.0 470 600 ma624d-12eru 24 9.0 - 36.0 287 7 ?2.0 ?50 ?2 87 20.0 100 600 ma624d-15eru 24 9.0 - 36.0 287 7 ?5.0 ?00 ?0 87 20.0 100 600 ma624d-24eru 24 9.0 - 36.0 287 7 ?4.0 ?25 ?.25 87 20.0 47 600 ma648s-03eru 48 18.0 - 75.0 156 3 3.3 1,500 75 80 20.0 1,800 300 ma648s-05eru 48 18.0 - 75.0 148 3 5.0 1,200 60 84 20.0 1,000 300 ma648s-12eru 48 18.0 - 75.0 144 3 12.0 500 25 87 20.0 100 300 ma648s-15eru 48 18.0 - 75.0 142 3 15.0 400 20 88 20.0 100 300 ma648s-24eru 48 18.0 - 75.0 144 3 24.0 250 12 87 20.0 47 300 ma648d-05eru 48 18.0 - 75.0 150 3 ?.0 ?00 ?0 83 20.0 470 300 ma648d-12eru 48 18.0 - 75.0 144 3 ?2.0 ?50 ?2 87 20.0 100 300 ma648d-15eru 48 18.0 - 75.0 144 3 ?5.0 ?00 ?0 87 20.0 100 300 ef? ciency vs output load : 48 vdc input ef? ciency vs input voltage : 48 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
www.micropowerdirect.com typical connection the diagram above illustrates a typical connection of the MA600ERUi series for applications that require meeting emc standards. the units do not require external components to operate as speci ed. some notes on this diagram (starting with the input circuit) are: 1. it is recommended that an external fuse be used. the recommended fuse is shown in the model chart on page 2. 2. an external mov is recommended on the input to protect the unit in the event of a surge. a recommended value is given in the table at right. 3. the output ltering capacitor (c 3 ) is a low esr electrolytic capacitor. care must be taken in choosing this capacitor not to exceed the capacitive load speci cation for the unit. voltage derating of capacitors should be 80% or above. typical board layout : single output with external filter/surge components 5. recommended values for components are: component 24 v in 48 v in mov s14k35 s14k60 c 1 330 f/50v 330 f/100v c 2 1.0 f/50v 1.0 f/100v ldm 1 4.7 h 4.7 h c y1 1 nf/2 kv 1 nf/2 kv c y2 1 nf/2 kv 1 nf/2 kv c 3 10 f 10 f 4. in many applications simply adding input/output capaci- tors will enhance the input surge protection and reduce output ripple suf ciently. t ypically, the value of the input capacitor should be 10 f to 47 f . the output capacitor would be 10 f. 5. input noise and surge suppression modules are available for a number of mpd dc/dc power supplies. for a recommen- dation for the ma600xeru series, please contact the factory. 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 : dual output with external filter/surge components
