rev.3.6 2014/02/26 web site: http://www.acbel.com 7 the description for each region of time sequence ? region i (1) the input voltage is under 85vrms, so the unit has no output and the ena signal is high (open collector). (2) input under voltage lockout (uvlo) action. the unit starts the turn on sequence. when the input voltage reaches 85vac and it delays 300ms, th e inrush signal changes from low to high. when the inrush signal is low, the internal transis tor of the unit between r terminal and +bc terminal is open. therefore, the inrush current can be suppressed by external resistor. when the inrush signal is high, the internal transistor of u nit is short. therefore, the external resistor is b y- passed by internal transistor. the voltage of bulk capacitors ( bc) should be more than 95% of the rectification i nput voltage before inrush signal changes to high. if no t, the unit could be damaged by inrush current. (3) when the inrush signal is high and then delays 100ms, the pfc_ctrl signal changes from low to high. which means the pfc converter turns on and the bc will be boosted to 385vdc (typ). (4) when the pfc_ctrl is high as well as bc reache s 360v and then delays 300ms, the dc/dc_ctrl signal will change from low to high. aft er the steps mentioned the output voltage of unit starts to increase to specified voltage level. (5) when the output voltage of dc9010-690g reaches 13.7v (typ) at start up, the ena signal is pulled low to indicate that unit finished the turn on sequence. the unit finished the turn on sequence through the steps above. ? region ii the over temperature protection (otp) action. when the baseplate temperature (refer to spec. figure 2) of the unit rises to 110 (typ), both pfc and dc/dc converters turns off and the output shuts down. when the baseplate temperatu re decreases to 90 (min), the output au- to-recovers. ? region iii pfc output over voltage protection (ovp) action. wh en bc is over 424v (typ), the pfc converter turns off. the pfc output voltage aut o-recovers if the failure is removed. ? region iv output ovp action. the output ovp mode is clamped. 500 watt, high efficiency, ac/dc power modules smv-500 www.astrodynetdi.com astrodyne usa: 1-800-823-8082 astrodyne pacific: 886-2-26983458
rev.3.6 2014/02/26 web site: http://www.acbel.com 8 ? region v output over current protection (ocp) action. when t he output current of the unit is over limitation, the output voltage steps down. if the failure mode is removed, the output voltage auto-recovers. ? region vi (1) input uvlo action. when the input voltage is un der 80vac (typ) , the pfc_ctrl signal changes from high to low, which means that the pfc converter turns off. after bc reduces to 300v, the inrush signal changes from high to low at the same time. (2) when the inrush is low and delays 5ms, the dc/d c_ctrl changes from high to low, which means the dc/dc converter turns off. (3) when the output voltage of dc9010-690g decrease s to 13.7v (typ), the ena signal changes from low to high. the unit turns off through the steps of region vi. 500 watt, high efficiency, ac/dc power modules smv-500 www.astrodynetdi.com astrodyne usa: 1-800-823-8082 astrodyne pacific: 886-2-26983458
