EASY621-DC-TCX +EASY200-EASY + EASY620-DC-TC
fixed in a car , power supply should be 24vdc from the car , but the voltage is coming about 27-28vdc & it is not stabilised , the basic unit get damaged , we changed but we are worried to get damage again , that is why i am asking what you will use in this case to avoide this problem , is there any power supply regulator to get pure dc power.. ?
