notes: 1. output load regulation is speci ed for a load change of 10% to 100%. 2. these units should not be operated with a load under 10% of full load. operation at no-load may cause damage to the unit. 3. these converters will oper- ate without external com- ponents. however, when measuring output ripple, it is recommended that an external ceramic capaci- tor be placed from the +vout pin to the -vout pin. an input capacitor will enhance stability over temperature and input line variations. recommended capacitor values are given in the table above. for applications requiring very low output noise levels, a simple lc lter should be effective. 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. vin input capacitor vout output capacitor 5 vdc 4.7 f 5 vdc 10.0 f 12 vdc 2.2 f 9 vdc 4.7 f 24 vdc 1.0 f 12 vdc 2.2 f 15 vdc 1.0 f 24 vdc 0.47 f other input/output combinations are available (i.e. 3.3 vdc). contact the factory for details at: sales@micropowerdirect.com model selection guide notes: ? all dimensions are typical in inches (mm) ? tolerance x.xx = ?.01 (?.25) ? pin 1 is marked by a ?ot?or indentation on the side of the unit 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 E101E 5 4.5 - 5.5 250 20 5.0 200.0 20.0 15 78 500 e102e 5 4.5 - 5.5 253 20 9.0 111.0 12.0 15 79 500 e103e 5 4.5 - 5.5 262 20 12.0 83.0 9.0 15 80 500 e104e 5 4.5 - 5.5 250 20 15.0 67.0 7.0 15 78 500 e111e 12 10.8 - 13.2 107 16 5.0 200.0 20.0 15 78 200 e112e 12 10.8 - 13.2 104 16 9.0 111.0 12.0 15 80 200 e113e 12 10.8 - 13.2 103 16 12.0 83.0 9.0 15 81 200 e114e 12 10.8 - 13.2 105 16 15.0 67.0 7.0 15 79 200 e121e 24 21.6 - 26.4 53 7 5.0 200.0 20.0 15 79 100 e122e 24 21.6 - 26.4 52 7 9.0 111.0 12.0 15 80 100 e123e 24 21.6 - 26.4 51 7 12.0 83.0 9.0 15 81 100 e124e 24 21.6 - 26.4 53 7 15.0 67.0 7.0 15 79 100 e125e 24 21.6 - 26.4 52 7 24.0 42.0 4.0 15 80 100 mechanical dimensions pin description 1-vin 2+vin 3 -vout 4 +vout pin connections derating curve 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
