model selection guide mechanical dimensions mechanical notes: ? all dimensions are typical in inch es (mm) ? tolerance x.xx = 0.01 (0.25) ? leads are gold plated for improved solderability. notes: 1. when measuring output ripple, it is recommended that an external 0.47 f ce- ramic capacitor be placed from the +vout pin to the -vout pin for single output units and from each output to common for dual output units. 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. operation at no-load will not damage these units. however, they may not meet all speci? cations. 4. dual output units may be connected to provide a 10 vdc, 24 vdc or 30 vdc output. to do this, connect the load across the positive (+vout) and negative (-vout) outputs and ? oat the output common. 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 sup- plied 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 (esr <1.0 at 100 khz) capacitor be mounted close to the converter. for 5v input units a 10 f is recommended, for 12v input units, a 3.3 f; and for 24v & 48v units a 2.2 f. 6. it is recommended that a fuse be used on the input of a power supply for protec- tion. see the table above for the correct rating. model number input output ef? ciency (%, typ) fuse rating slow-blow (ma) voltage (vdc) current (ma) re? ected ripple current (ma, typ) voltage (vdc) current (ma, max) current (ma, min) nominal range full-load no-load a501rw 12 9.0 - 18.0 429 20 25 3.3 1,200.0 60.0 77 1,500 a502rw 12 9.0 - 18.0 514 20 25 5.0 1,000.0 50.0 81 1,500 a503rw 12 9.0 - 18.0 595 20 25 12.0 500.0 25.0 84 1,500 a504rw 12 9.0 - 18.0 595 20 25 15.0 400.0 20.0 84 1,500 a505rw 12 9.0 - 18.0 514 20 25 5.0 500.0 25.0 81 1,500 a506rw 12 9.0 - 18.0 595 20 25 12.0 250.0 12.5 84 1,500 a507rw 12 9.0 - 18.0 595 20 25 15.0 200.0 10.0 84 1,500 A511RW 24 18.0 - 36.0 209 5 15 3.3 1,200.0 60.0 79 700 a512rw 24 18.0 - 36.0 251 5 15 5.0 1,000.0 50.0 83 700 a513rw 24 18.0 - 36.0 291 5 15 12.0 500.0 25.0 86 700 a514rw 24 18.0 - 36.0 291 5 15 15.0 400.0 20.0 86 700 a515rw 24 18.0 - 36.0 251 5 15 5.0 500.0 25.0 83 700 a516rw 24 18.0 - 36.0 291 5 15 12.0 250.0 12.5 86 700 a517rw 24 18.0 - 36.0 291 5 15 15.0 200.0 10.0 86 700 a521rw 48 36.0 - 75.0 104 3 10 3.3 1,200.0 60.0 79 350 a522rw 48 36.0 - 75.0 126 3 10 5.0 1,000.0 50.0 83 350 a523rw 48 36.0 - 75.0 145 3 10 12.0 500.0 25.0 86 350 a524rw 48 36.0 - 75.0 145 3 10 15.0 400.0 20.0 86 350 a525rw 48 36.0 - 75.0 126 3 10 5.0 500.0 25.0 83 350 a526rw 48 36.0 - 75.0 145 3 10 12.0 250.0 12.5 86 350 a527rw 48 36.0 - 75.0 145 3 10 15.0 200.0 10.0 86 350 a551rw 5 4.5 - 7.0 1,056 70 100 3.3 1,200.0 60.0 75 3,000 a552rw 5 4.5 - 7.0 1,265 70 100 5.0 1,000.0 50.0 79 3,000 a553rw 5 4.5 - 7.0 1,463 70 100 12.0 500.0 25.0 82 3,000 a554rw 5 4.5 - 7.0 1,463 70 100 15.0 400.0 20.0 82 3,000 a555rw 5 4.5 - 7.0 1,265 70 100 5.0 500.0 25.0 79 3,000 a556rw 5 4.5 - 7.0 1,463 70 100 12.0 250.0 12.5 82 3,000 a557rw 5 4.5 - 7.0 1,463 70 100 15.0 200.0 10.0 82 3,000 pin single dual pin single dual 2, 3 -vin -vin 14 +vout +vout 9 no pin common 16 -vout common 11 nc -vout 22, 23 +vin +vin nc: no connection pin connections single output dual output 6,800 f max 1,000 f max capacitive load 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
