High Frequency Converter
What Is a High-Frequency Voltage Converter and What Are the Advantages of the OLI Brand?
In the world of modern construction, this concrete casting tool plays a key role in achieving efficiency and optimal results. One of the vital components in operating an internal vibrator (concrete vibrator) is a frequency and voltage converter. This device is essential to ensure the vibrator operates optimally, stably, and continuously—without being affected by electrical fluctuations.
What Is a High-Frequency Voltage Converter?
A high-frequency converter is a device that transforms high-voltage, low-frequency power from a power source such as the grid or generator (e.g., 230V, 50Hz) into low-voltage, high-frequency power required by other tools like internal vibrators. Its main functions are to:
- Stabilize electric current and frequency
- Prevent equipment damage due to unstable voltage
- Deliver maximum and efficient power to high-frequency vibrators
Applications in Construction

This tool is commonly used in:
- Concrete casting work, to power high-frequency internal vibrators
- High-rise building and bridge construction, where concrete vibration quality is critical
- Precast concrete plants that require continuous vibrator operation
