*High power regulator, stepless regulation, help adjust speed, temperature, voltage and light. *Using the new two-way high-power thyristor, current up to 25A, a good solution to the problem of over-current electric wire in the case of cooling the resistance is too small to cause. *Adopt iron outshell design, solid and firm, wear resistance and with fine durability. *Separate switch control, freely control the input power and cut off power. *Adopt multi functional industrial sockets, thicken copper part design, with fine contact and safety.
