一、电源电路特点:1.稳压范围宽:采用新型厚膜STRS6309和取样比较IC(SE140),稳压性强(AC100～245V,输出电压变化在3%以下);2.维修安全方便;由于采用光电耦合电路(TLP621)进行取样控制,将冷热底盘隔离;3.主电源电压
First, the power circuit features: 1. Wide range of voltage regulator: a new thick film STRS6309 and sampling comparison IC (SE140), strong regulation (AC100 ~ 245V, the output voltage changes in 3% or less); 2. Maintenance safe and convenient; As the use of optical coupling circuit (TLP621) sampling control, the hot and cold chassis isolation; 3. The main power supply voltage
