>> 1 the 1500wfr series is a family of low cost single and dual output 15w dc/dc converters specifically designed for space- critical applications. these models operate from wide (2:1) input voltage ranges of 18 to 36 or 36 to 72 vdc; and provide regulated outputs of 5, 12, 15, 12 or 15 vdc. standard features include 500 vdc input/output isolation, an internal input filter, line/load regulation of 1.0% and a minimum switch- ing frequency of 190 khz. all models are packaged in compact, low profile 1 x 2 x 0.4 inch metal case. this miniature size yields a power density as high as 18.75 watts/in 3 . operation is specified over the full operating temperature range of -25 o c to +71 o o c. cooling is by free-air convection. d d e e s s c c r r i i p p t t i i o o n n s s 1500wfr series ? ? 1 1 5 5 w w c c o o n n t t i i n n u u o o u u s s o o u u t t p p u u t t p p o o w w e e r r ? ? c c o o m m p p a a c c t t 1 1 x x 2 2 x x 0 0 . . 4 4 c c a a s s e e ? ? i i n n d d u u s s t t r r y y s s t t a a n n d d a a r r d d p p i i n n - - o o u u t t ? ? u u p p t t o o 8 8 2 2 % % e e f f f f i i c c i i e e n n c c y y ? ? - - 2 2 5 5 o o c c t t o o + + 7 7 1 1 o o c c o o p p e e r r a a t t i i n n g g t t e e m m p p e e r r a a t t u u r r e e r r a a n n g g e e ? ? 1 1 8 8 . . 7 7 5 5 w w / / i i n n 3 3 p p o o w w e e r r d d e e n n s s i i t t y y ? ? l l o o w w c c o o s s t t f f e e a a t t u u r r e e s s i i n n p p u u t t c c h h a a r r a a c c t t e e r r i i s s t t i i c c s s o o u u t t p p u u t t c c h h a a r r a a c c t t e e r r i i s s t t i i c c s s unit/comments input voltage range 24 vdc input models vdc 48 vdc input models vdc input filter pi networks unit/comments %; output voltage at nominal line & fl %; equal output loads 10% of full load % 1 % 2 mv p-p, nom.line fl, 20mhz b.w. using 1 f bypass capacitor s to within 1% error band for 25% step load change % per o c current limit, continuous min typ max 1.0 1.0 0.2 1.0 100 500 0.02 single and dual output dc/dc converter min 18 36 typ 24 48 max 36 72 g g e e n n e e r r a a l l c c h h a a r r a a c c t t e e r r i i s s t t i i c c s s unit/comments switching frequency khz isolation voltage vdc, 1 minute isolation resistance mohm, 500vdc min 190 500 1000 typ max output voltage accuracy output voltage balance dual outputs minimum load line regulation load regulation ripple/noise transient response temperature coefficient short circuit protection 1 = % output voltage measured from min. input line to maximum at 100% load. 2 = output voltage measured from 25% load to 100% load, at nominal line. www.make-ps.com e-mail:info@make-ps.com
