Constant Voltage And Constant Current Controller . From a design and arc control standpoint, there are two fundamentally different types of welding power sources. The cc control loop also incorporates a current sense amplifier with gain of 10. Buy Constant voltage Constant current from www.aliexpress.com The voltage reference combined with one operational amplifier makes it an ideal voltage controller. The tsm1011 integrates one voltage reference and two operational amplifiers (with ored outputs —common collectors). The tsm1011 is a highly integrated solution for smps applications requiring cv (constant voltage) and cc (constant current) modes.
