Advanced Built-in Protection Systems

This custom current voltage rectifier includes comprehensive safeguards to protect both the power supply and your valuable workpiece. Overcurrent protection (OCP) instantly limits output if a short occurs in the electropolishing tank. Overtemperature protection (OTP) engages a fan speed increase and automatic shutdown if internal heat exceeds safe limits. Overvoltage protection (OVP) prevents voltage spikes that could damage sensitive electronics. Phase loss protection ensures the unit does not operate with missing input phases. Reverse polarity protection prevents damage from incorrect tank connections. Soft-start ramp-up functionality gradually increases output over a user-defined period, preventing current surges that can cause uneven polishing or part damage.
