logic control ps_on /l(power supply enable) the power supply output will be enabled when this signal is pulled low (< 0.8 v). high = output v1 off low = output v1 on vin_good/h (input ok) active high signal asserted when the input voltage rises above the min input voltage specifed. this signal is internally pulled up through 4.7 k ohms to the 3.3 v housekeeping voltage. pok/h (output ok) active high signal asserted when the output is within regulation. this signal is internally pulled up through 1.0 k ohms to the 3.3 v housekeeping voltage. tach_1 this open collector signal generates two pulses per each fan revolution. this signal is eternally pulled up to the housekeeping voltage. ps_kill this signal will cause the output to shut down when drive high (> 24 v) or left foating. the ps_kill will cause the output to latch off and requires recycle of ps_on or dc input to reset. environmental specifcations operating temperature +10 c to +45 c, able to start-up at -10 c storage temperature -40 c to +70 c altitude, operating 10,000 ft. electromagnetic susceptibility/input transients - en61000-3-2, -3-3 - en61000-4-2, 4.3, 4-4, -4-5, 4-11 - en55024:1998 rohs & lead-free compliant (no tantalum caps.) humidity 20 to 90% rh, non-condensing shock and vibration specifcatons complies with astec std. specifcations. mtbf (calculated) 500k hours at full load, 25 c ordering information output nominal output voltage set point set point tolerance total regulation minimum current maximum current output ripple p/p over current options ds450dc-3 12.0 vdc 3.3 vsb 0.2% 1% +5/-3% +5/-4% 0 a 0 a 37.0 a 3.0 a 120 mv 60 mv 39.5 - 44.4% 4.9 a avg, 7 a max standard ds450dc-3-002 12.0 vdc 3.3 vsb 0.2% 1% +5/-3% +5/-4% 0 a 0 a 37.0 a 3.0 a 120 mv 60 mv 39.5 - 44.4% 4.9 a avg, 7 a max reverse air DS550DC-3 12.0 vdc 3.3 vsb 0.2% 1% +5/-3% +5/-4% 0 a 0 a 45.0 a 3.0 a 120 mv 60 mv 48.0a - 54.0a 4.9 a avg, 7 a max standard DS550DC-3-003 12.0 vdc 3.3 vsb 0.2% 1% +5/-3% +5/-4% 0 a 0 a 45.0 a 3.0 a 120 mv 60 mv 48.0a - 54.0a 4.9 a avg, 7 a max reverse air *over current latches off if overcurrent lasts over 1 second, otherwise it is auto recovery. *for 5 vsb, please contact marketing department. ds450-3/ds550-3 data sheet
