72. und U2 a phase shift PWM controller from Unitrode 4 PWM signals A OUT B out C out and D OUT is wired to the output module where the output current is generated Aux power supply The aux power supply module delivers the supply voltages for control board and other modules connected to it The different supply voltages are for CPU fans digital and analog circuits as these don t operate at same supply voltage AC line monitor The AC input line is monitored and the system will go in fault mode in case of malfunction at the AC line Monitoring of the AC line is built around Q1 Q2 Q3 which measure the voltage across the three phase line input and send an error signal via U1 U4 and U7 to the Line OK which is connected to the I loop control board Aux power loop amp CPU This circuit regulates different voltages for supplying of the microprocessor CPU and the I loop control board The different voltage supplies are regulated by U5 and U12 and a transformer T2 Available supply voltages are 15 Vdc 15 Vdc 12 Vdc and 5 Vdc DANFYSIK A S DENMARK 4 7 3 4 7 4 4 8 4 9 MAGNET POWER SUPPLY SYSTEM 9100 Me 57 Aux power FAN The fan and will go on if the MPS is power on and off if the MPS is off controlled by the signal FAN CONTROL Aux power primary Supply voltages 5 V and 20 V is generated by U3 and T1 respectively DCCT transducer DCCT current transducer measures the output current and controls
