Here is a special type light controller, it is differ from JL-202 series thermal sensing controller(such as jl202A, jl202B, jl202C and jl202D). JL-203C most significant performance both electronic circuit assisted thermal switch and IR filtered phototransistor. in this case, jl203c also functionalise with JL-202 series work principle. however, as light controller with IR Filtered phototransistor reach to good precision light sensitivities, so you can easily experienced subtle changes around JL-203C and jl202 series on the function delay-time property. another vital usage, light control is multi voltage, so it is More versatile,and place it in harsh environment to keep light fixture normal work. contran to jL-202 series, then it is best suit for normal work during steady voltage conditional.
