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. 2. transient recovery is measured to within a 1% error band for a load step change of 25%. 3. short circuit protection is provided by a ?iccup mode circuit. 4. all units are rated for en 55022 (ce/re) class a without external components. they will meet class b with the addition of the dcfm-0x (or a similar discrete lter circuit as shown on page 3). contact the factory for more information. 5. to meet the requirements of en 61000-4-4 ( ? kv), external components are needed, as shown on page 3. with the addition of the dcfm-0x , en 61000-4-4 (? kv) can be achieved. contact the factory for more information. 6. to meet the requirements of en 61000-4-5 ( ? kv), external components are needed. this can be done discretely (as shown on page 3), or with the addition of the dcfm-0x . contact the factory for more information. 7. 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. 9. 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-05erui 24 9.0 - 36.0 301 12 5.0 1,200 60 83 20.0 2,200 2,000 ma624s-12erui 24 9.0 - 36.0 287 12 12.0 500 25 87 20.0 680 2,000 ma624s-15erui 24 9.0 - 36.0 284 12 15.0 400 20 88 20.0 680 2,000 ma624s-24erui 24 9.0 - 36.0 287 12 24.0 250 12 87 20.0 680 2,000 ma648s-05erui 48 18.0 - 75.0 151 3 5.0 1,200 60 83 20.0 2,200 1,000 ma648s-12erui 48 18.0 - 75.0 143 3 12.0 500 25 87 20.0 680 1,000 ma648s-15erui 48 18.0 - 75.0 142 3 15.0 400 20 88 20.0 680 1,000 ma648s-24erui 48 18.0 - 75.0 143 3 24.0 250 12 87 20.0 680 1,000 ef? ciency vs output load 24 vdc input ef? ciency vs input voltage 24 vdc input ef? ciency vs input voltage 48 vdc input ef? ciency vs output load 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. an external tvs is recommended on the input to protect the unit in the event of a voltage spike. a recommended value is given in the table at right. 4. the output ltering capacitor (c 4 ) 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 : with external filter/surge components 5. recommended values for components are: component 24 v in 48 v in mov s14k35 s14k60 ldm 56 h 56 h tvs smcj48a smcj90a c 1 330 f/50v 330 f/100v c 2, c 3 2.2 f/50v 2.2 f/100v lcm 2.2 mh 2.2 mh c 4 10 f 10 f typical connection : with dcfm-0x isurge suppression and filter module 6. the drawing below shows a suggested board layout for the emc/emi circuit shown above. filtering capacitor (c 4 ) is a low esr resistance electrolytic capacitor. care must be taken in choosing this capacitor not to exceed the capacitive load speci cation for the unit. 7. 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 > 330 f . the output capacitor would be 10 f. input noise and surge suppression modules are available for a number of mpd dc/dc power supplies. an MA600ERUI connection with the d cfm-02 (noise suppression) module connected to the input is shown below. the recommended input capacitor (c 1 ) is a 330 f/50v for 24 vdc input models and 330 f/100v for 48 vdc input units. the output ca pacitor would be 10 f. for pric ing or full technical information on these modules ( dcfm-01, d cfm-02 and dcfm-03 ) 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
