Miller IHPS5 10-50 is a 10 to 50 kHz induction heating power source capable of generating 5kW of output at 100% duty cycle. It uses three-phase input power and has protection for overheating. The unit also features a 14-pin remote control receptacle for added convenience. With its ability to heat metal objects quickly and efficiently, the IHPS5 10-50 is ideal for a variety of applications, including hardening, annealing, brazing, and soldering.
