model selection guide mechanical dimensions notes: 1. when measuring output ripple, it is recommended that an external 0.47 f ceramic capacitor be placed from +v out to -v out for single output models or from each output to common for dual output models. for noise sensitive applications, the use of 3.3 f capacitors will reduce the output ripple. 2. transient recovery is measured to within a 1% error band for a load step change of 75% to 100%. 3. the maximum control current at the on/off input (pin 1) during a logic high (+5v) is 500 a. the maximum control current to the on/off pin at logic low (0v) is -500 a. if the on/off pin is left open, the unit operates. if grounded, the unit will shut off. 4. operation at no-load will not damage these units. however, they may not meet all speci cations. 5. the converter should be connected to a low ac-impedance source. an input source with a highly inductive impedance may affect the stability of the converter. in applications where the converter output loading is high and input power is supplied over long lines, it may be necessary to use a capacitor on the input to insure start-up. in this case, it is recommended that a low esr (<1.0 ? at 100 khz) capacitor be mounted close to the converter. for 24v input units a 4.7 f is recommended and for 48v input models, a 2.2 f. 6. 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. notes: all dimensions are typical in inches (mm) tolerance x.xx = ?.01 (?.25) pin 1 is marked by a ?ot or indentation on the unit model number input output ef ciency (%, typ) output 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 ml624s-03ru 24 9.0 - 36.0 262 30 3.3 1,450 218 76 330 1,500 ml624s-05ru 24 9.0 - 36.0 316 30 5.0 1,200 180 79 330 1,500 ml624s-12ru 24 9.0 - 36.0 301 30 12.0 500 75 83 100 1,500 ml624s-15ru 24 9.0 - 36.0 301 30 15.0 400 60 83 100 1,500 ml624s-24ru 24 9.0 - 36.0 301 30 24.0 250 38 83 100 1,500 ml624d-05ru 24 9.0 - 36.0 301 30 5.0 600 90 82 100 1,500 ml624d-12ru 24 9.0 - 36.0 301 30 12.0 250 38 83 100 1,500 ml624d-15ru 24 9.0 - 36.0 301 30 15.0 200 30 83 100 1,500 ml648s-03ru 48 18.0 - 75.0 131 20 3.3 1,450 218 76 330 750 ml648s-05ru 48 18.0 - 75.0 158 20 5.0 1,200 180 79 330 750 ml648s-12ru 48 18.0 - 75.0 151 20 12.0 500 75 83 100 750 ml648s-15ru 48 18.0 - 75.0 151 20 15.0 400 60 83 100 750 ml648s-24ru 48 18.0 - 75.0 151 20 24.0 250 38 83 100 750 ml648d-05ru 48 18.0 - 75.0 151 20 5.0 600 90 82 100 750 ml648d-12ru 48 18.0 - 75.0 151 20 12.0 250 38 83 100 750 ml648d-15ru 48 18.0 - 75.0 151 20 15.0 200 30 83 100 750 pin single pin dual 1 remote on/off 1 remote on/off 2-v in 2-v in 6 nc 6 common 8nc 8-v out 9+v out 9+v out 11 -v out 11 common 16 +v in 16 +v in nc = no connection pin connections board layout 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 www.micropowerdirect.com
