notes: 1. output load regulation is speci? ed for a load change of 20% to 100%. 2. when measuring output ripple, it is recommended that an external 0.33 f ceramic capacitor be placed from the +vout pin to the -vout pin. 3. operation at no-load will not damage these units. how- ever, they may not meet all speci? cations. 4. the 5v, 12v and 24v input units do not require external components to operate, but the use of a low esr capaci- tor (approximately 10 u f, esr <1.0 at 100 khz) mounted close to the converter input pins is recommended. for 48 vdc input units, an input capacitor should always be used. dependent upon the application, a value be- tween 4.7 f and 47 uf should be suf? cient. 5. it is recommended that a fuse be used on the input of a power supply for protection. see the table above for the correct rating. model number input output load regulation (% max) ef ciency (%, typ) fuse rating slow-blow (ma) voltage (vdc) current (ma) voltage (vdc) current (ma, max) current (ma, min) nominal range full-load no-load E101I 5 4.5 - 5.5 267 25 5.0 200.0 4.0 10 75 500 e102i 5 4.5 - 5.5 260 25 9.0 111.0 2.0 10 77 500 e103i 5 4.5 - 5.5 256 25 12.0 83.3 2.0 10 78 500 e104i 5 4.5 - 5.5 257 25 15.0 66.6 2.0 10 78 500 e105i 5 4.5 - 5.5 257 25 24.0 41.6 2.0 10 78 500 e111i 12 10.8 - 13.2 112 16 5.0 200.0 4.0 10 75 200 e112i 12 10.8 - 13.2 109 16 9.0 111.0 2.0 10 77 200 e113i 12 10.8 - 13.2 107 16 12.0 83.3 2.0 10 78 200 e114i 12 10.8 - 13.2 107 16 15.0 66.6 2.0 10 78 200 e115i 12 10.8 - 13.2 107 16 24.0 41.6 2.0 10 78 200 e121i 24 21.6 - 26.4 56 10 5.0 200.0 4.0 10 75 100 e122i 24 21.6 - 26.4 55 10 9.0 111.0 2.0 10 77 100 e123i 24 21.6 - 26.4 54 10 12.0 83.3 2.0 10 78 100 e124i 24 21.6 - 26.4 54 10 15.0 66.6 2.0 10 78 100 e125i 24 21.6 - 26.4 54 10 24.0 41.6 2.0 10 78 100 e131i 48 43.2 - 52.8 28 7 5.0 200.0 4.0 10 75 50 e132i 48 43.2 - 52.8 27 7 9.0 111.0 2.0 10 76 50 e133i 48 43.2 - 52.8 27 7 12.0 83.3 2.0 10 76 50 e134i 48 43.2 - 52.8 27 7 15.0 66.6 2.0 10 76 50 e135i 48 43.2 - 52.8 27 7 24.0 41.6 2.0 10 76 50 models with other outputs are available. contact the factory for details!! model selection guide notes: ? all dimensions are typical in inches (mm) ? tolerance x.xx = 0.01 (0.25) ? pin 1 is marked by a ?dot? or indentation on the side of the unit ? dimensions indicated on the drawing are as follows: mechanical dimensions pin description 1-vin 2+vin 3 -vout 4 +vout pin connections (f max) 220 capacitive load dimension input voltage 5, 12 & 24v 48v ?w? 0.24 (6.0) 0.29 (7.5) ?x? 0.05 (1.25) 0.08 (2.00) micropower direct www.micropowerdirect.com 292 page street ste d stoughton, ma 02072 ? tel: (781) 344-8226 ? fax: (781) 344-8481 ? e-mail: sales@micropowerdirect.com derating curve
