1. The "Iron Tower Brand" series of AC parameter voltage regulators integrates ultra wide voltage regulation, high precision, high reliability, fast response, and bidirectional anti-interference. There is no need for standby, and the load can be connected and used immediately upon startup.

2. Strong bidirectional anti-interference ability! It can effectively filter out various frequencies of positive and negative pulses and surge voltages generated by the power grid and loads, and has strong lightning resistance, high safety, reliability, and stability.

3. The voltage stabilization range is particularly wide, especially suitable for situations with large voltage fluctuations.

4. Has strong overload capacity.

5. It has automatic protection features. When the load is short circuited or internal components are damaged, the output voltage automatically drops to 0 volts. Never experience overvoltage output, ensuring the safe operation of user devices.

6. High quality raw materials and power components are selected, and there are no active components inside the machine, resulting in a low failure rate, particularly long lifespan, and more reliable operation. It can be considered as a "semi permanent equipment".
