Hello, Is anybody to help me?I am a newcomer to this forum and have a question and need guidance : I need a driver to run an on/off actuator as proportional actuator.I made some experiments and found that core of both actuators(consisting of thermal wax and spring)is the same and the difference in them is electronic driver(the on/off actuator doen't have electronic driver,but proportional actuator has it),I need this electronic driver-its circuit or description about its performance- Looking forward to hearing you, Many thanks in advance, Alireza121
