28 / 31 page MODEL : AIF - PFC Series March 2006 REVISION 09 SH 28 of 31 Technical Reference Note AIF - PFC Power Factor Correction Series Brown Out Ride Through Brown Out conditions occurs when there is a transient break in input current. During this period the external output bulk capacitor holds up the voltage to the load until input current is restored. When the input voltage is restored the PFC module will continue delivering power to the load 315V for Vadj to 76% (390V for Vadj to 100%) 290V for Vadj to 76% (380V for Vadj to 100%) 280V LOW +O/P -O/P 85 to 265Vac L1 L2 9 8 1 16 + Output to AMPSSô Modules or other load APA 250V(Min) INPUT VOLTAGE OUTPUT VOLTAGE PFW BROWN OUT AC INPUT FOR BROWN OUT < 20ms 280V LOW LOW 250V(Min) INPUT VOLTAGE OUTPUT VOLTAGE PFW LD ENABLE BROWN OUT FOR BROWN OUT > 20ms Load Disabled Charging of Output Capacitor 315V for Vadj to 76% (390V for Vadj to 100%) 290V for Vadj to 76% (380V for Vadj to 100%) After a Brown Out condition where the output voltage has not dropped below 250Vdc, the module will recover when input power is restored. The PFW signal can be used to monitor input power loss. |
