OLI CM Frequency & Voltage Converters in UAE
OLI CM Frequency & Voltage Converters
In professional concrete construction, consistent vibration performance is just as important as the vibrator itself. High-frequency internal and external concrete vibrators require a dedicated power supply capable of delivering stable voltage and frequency throughout the concrete placement process. Without the correct converter, even the highest-quality vibrator cannot operate at its intended performance.
The OLI CM Frequency & Voltage Converter Series has been engineered specifically to power OLI high-frequency concrete vibrators, providing a continuous 42 V, 200 Hz three-phase output from standard single-phase or three-phase electrical supplies. These electromechanical converters use a motor coupled with a permanent magnet generator to deliver stable power while maintaining operator safety through low-voltage operation.
At Liberty Enterprises, we supply genuine OLI CM Frequency & Voltage Converters in the UAE, helping contractors, precast manufacturers, ready-mix concrete plants, and infrastructure companies operate their high-frequency vibration systems with maximum reliability and efficiency.

What is a Frequency & Voltage Converter?
A frequency and voltage converter is an electromechanical device that transforms a standard electrical supply into the precise voltage and frequency required for high-frequency concrete vibrators.
Most high-frequency internal and external concrete vibrators are designed to operate at 42 V and 200 Hz, rather than directly from standard mains electricity. The CM Series converts either 230 V single-phase or 400 V three-phase input into the correct output needed for professional concrete vibration equipment.
This controlled power supply allows immersion vibrators and external vibrating motors to maintain a constant operating speed, ensuring consistent concrete consolidation throughout the entire pour.
Why Are Frequency & Voltage Converters Important?
Concrete consolidation depends on consistent vibration. Fluctuations in voltage or frequency can reduce vibrator performance, leading to incomplete compaction, trapped air, and inconsistent concrete quality.
The CM Series is designed to eliminate these issues by delivering a stable electrical output for continuous-duty operation. OLI’s design includes permanent magnet technology and an optimized cooling system that helps prevent overheating while supporting long operating cycles.
For contractors and precast manufacturers, this means:
- Stable vibration performance
- Consistent concrete density
- Reduced risk of honeycombing
- Reliable operation during long pours
- Improved productivity on site
Key Features of OLI CM Frequency & Voltage Converters
Stable 42V / 200Hz Output
The CM Series delivers the dedicated voltage and frequency required for professional concrete vibrators, ensuring consistent operating performance throughout the concrete placement process.
Continuous Duty Operation (S1)
Construction and precast applications often require equipment to operate for extended periods. The CM Series is designed for continuous S1 duty, providing dependable power throughout long working cycles without compromising performance.
Maintenance-Free Design
Permanent magnet technology eliminates many wear components found in conventional systems, resulting in a highly reliable converter that requires minimal routine maintenance.
Optimized Cooling System
A smooth cast aluminium body provides durability while making the unit easier to clean after use in demanding construction environments.

How to Select the Right CM Converter
Choosing the correct converter depends on:
Number of Vibrators
Different CM models can power one to four compatible high-frequency vibrators simultaneously.
Electrical Supply
Select a converter that matches your available site power supply, whether single-phase or three-phase.
Project Scale
Small building projects may require compact handle-type units, while large infrastructure and precast facilities benefit from higher-capacity frame or wheeled models.
Future Expansion
If additional vibrators may be required later, choosing a higher-capacity converter can provide greater operational flexibility.
Why Choose OLI?
OLI has established itself as a global leader in industrial vibration technology by developing complete concrete consolidation systems rather than standalone products.
