model selection guide mechanical notes: all dimensions are typical in inch es (mm) tolerance x.xx = ?.01 (?.25) notes: 1. when measuring output ripple, it is recommended that an external 10.0 f ceramic capacitor be placed from the +vout pin to the -vout pin. for noise sensitive applications, the use of 47 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 remote on/off control input (pin 3) is referenced to -vin (pin 1). connection to the pin should be made through a 1k resistor and diode (1n4148). if it is not used, the control pin should be left open. 4. operation at no-load will not damage these units. however, they may not meet all speci ca- tions. 5. the +sense and -sense connections will compensate for up to 5% of vout. when not used, they should be connected directly to the appropriate output pin (+sense to +vout and -sense to -vout). 6. to improve performance and stability, a simple external lc lter can be added to the unit input. typical component values would be 1.0 h/10a & 1,000 f/25v for 12v input models; 2.2 h/10a & 1,000 f/50v for 24v input models; and 74.7 h/5a & 1,000 f/100v for 48v input models. 7. 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. 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 a simple external circuit may be used to adjust the converter output. to adjust the output down, connect a 5%, 3w resistor between the plus output pin and the vout trim pin. to adjust the output up, connect a 5%, 3w resistor between the minus output pin and the vout trim pin. to calculate the correct resistor value (in k? ) use: 3.3 v out up r adj = (v out - 1.24) x (2.87) - 10 v adj - v out other v out up r adj = (v out - 2.5) x (2.87) - 10 v adj - v out 3.3 v out down r adj = (v adj - 1.24) (v out - 1.24) x 2.87 - 10 v out - v adj other v out down r adj = (v adj - 2.5) (v out - 2.5) x 2.87 - 10 v out - v adj for up/down trimming capability, connect a 10 kw potentiometer between the plus and minus outputs with the wiper arm con- nected to the vout trim pin. pin single pin single 1 +vin 6 +sense 2 -vin 7 +vout 4 on/off 8 -vout 5 -sense 9 trim pin connections model number input output ef ciency (%, typ) capaci- tive load (? max) fuse rating slow-blow (ma) voltage (vdc) current (ma) voltage (vdc) current (ma, max) current (ma, min) nominal range full-load no-load c4001erw 12 9.0 - 18.0 2,558 20 3.3 8,000 400.0 86 21,000 5,000 c4002erw 12 9.0 - 18.0 3,876 20 5.0 8,000 400.0 86 13,600 5,000 c4003erw 12 9.0 - 18.0 3,876 20 12.0 3,300 165.0 86 2,360 5,000 c4004erw 12 9.0 - 18.0 3,831 20 15.0 2,666 133.0 87 1,510 5,000 c4011erw 24 18.0 - 36.0 1,264 15 3.3 8,000 400.0 87 21,000 3,000 c4012erw 24 18.0 - 36.0 1,873 15 5.0 8,000 400.0 89 13,600 3,000 c4013erw 24 18.0 - 36.0 1,894 15 12.0 3,300 165.0 88 2,360 3,000 c4014erw 24 18.0 - 36.0 1,873 15 15.0 2,666 133.0 88 1,510 3,000 c4021erw 48 36.0 - 75.0 625 10 3.3 8,000 400.0 88 21,000 1,500 c4022erw 48 36.0 - 75.0 926 10 5.0 8,000 400.0 90 13,600 1,500 c4023erw 48 36.0 - 75.0 926 10 12.0 3,300 165.0 90 2,360 1,500 c4024erw 48 36.0 - 75.0 926 10 15.0 2,666 133.0 90 1,510 1,500 mechanical dimensions external trim derating curves www.micropowerdirect.com
