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 operate without external components. however, when measuring out- put ripple, it is recommended that an external ceramic capacitor be placed from the +vout pin to the -vout pin. an input capacitor will enhance stability over tem- perature 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. after an output short circuit, the input power must be recycled to operate the unit. 5. given for frequency range of 5 to 500 hz and psd of 0.0248 g 2 /hz. tested on x, y & z axis for 60 minutes. 6. 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 3.3 vdc 4.7 f 3.3 vdc 10.0 f 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 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 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 (% typ) (% max) e101ei 5 4.5 - 5.5 290 50 5.0 200.0 20.0 12.8 15.0 69 500 e102ei 5 4.5 - 5.5 263 50 9.0 111.0 12.0 8.3 15.0 76 500 E103EI 5 4.5 - 5.5 256 50 12.0 83.0 9.0 6.8 15.0 78 500 e104ei 5 4.5 - 5.5 256 50 15.0 67.0 7.0 6.3 15.0 78 500 e111ei 12 10.8 - 13.2 117 21 5.0 200.0 20.0 12.8 15.0 71 200 e112ei 12 10.8 - 13.2 113 21 9.0 111.0 12.0 8.3 15.0 74 200 e113ei 12 10.8 - 13.2 107 21 12.0 83.0 9.0 6.8 15.0 78 200 e114ei 12 10.8 - 13.2 105 21 15.0 67.0 7.0 6.3 15.0 79 200 e121ei 24 21.6 - 26.4 58 17 5.0 200.0 20.0 12.8 15.0 72 100 e122ei 24 21.6 - 26.4 54 17 9.0 111.0 12.0 8.3 15.0 77 100 e123ei 24 21.6 - 26.4 54 17 12.0 83.0 9.0 6.8 15.0 77 100 e124ei 24 21.6 - 26.4 53 17 15.0 67.0 7.0 6.3 15.0 79 100 e151ei 3.3 2.97 - 3.63 432 76 3.3 303.0 30.0 15.0 20.0 70 200 e152ei 3.3 2.97 - 3.63 415 76 5.0 200.0 20.0 12.8 15.0 73 200 mechanical dimensions pin description 1-vin 2+vin 3 -vout 4 +vout pin connections www.micropowerdirect.com derating curve micropower direct we power your success - for less! 292 page street ste d stoughton, ma 02072 ? tel: (781) 344-8226 ? fax: (781) 344-8481 ? e-mail: sales@micropowerdirect.com
