Bias can be divided into positive and negative bias bias. In order to improve the reliability of the ringing current system, you need to back up the ringing IC200MDL940B IC200ALG264C IC200ALG320C IC200ALG264D IC200MDL241E IC200MDL241D IC200PWR102D IC200GBI001 IC200PWB001C IC200PWR102E IC200CHS022C IC200ALG620-AA IC200ALG620-DC IC200ALG620-CB IC693PWR330G IC693ALG223D IC693ALG392C IC693CHS392J IC693CPU364-CJ IC693PWR330G IC693ALG392 IC693ALG223 IC693BEM331 IC693CPU364-EK IC693PWR330 IC693CHS391M IC693BEM331 IC693PWR330 IC693CPU364 IC693ALG223 IC693ALG392 with the corresponding output if the alarm circuit SNAT, the module can be removed on the bus, so that the faulty module can be replaced in a timely manner in principle. In this way the modules in parallel, there is no quantity limitation. D generally Schottky diode. SNAT 604IFSREV_SNAT4041 provided by the Shenyang Electric Co., the people.
