## Summary description

Three-phase bridge rectifier EB889531831 by Urmax with maximum reverse voltage 1.6 kV and forward current rating 50 A. Designed to convert three-phase AC to DC in industrial and power-electronics applications. Suitable for use in motor drives, power supplies and rectification stages where these voltage and current limits are required. Provides reliable rectification for integration into control panels and equipment.

## Long description

The Urmax three-phase bridge rectifier model EB889531831 converts three-phase alternating current to direct current with a maximum reverse voltage of 1.6 kV and a continuous forward current rating of 50 A. Engineered for industrial and power-electronics installations, this rectifier is intended for integration into motor drives, power supplies and rectification stages where robust, predictable DC output and the stated voltage/current capacity are required.
Advantages
This three-phase bridge rectifier delivers stable DC conversion under rated conditions and is built to meet the electrical stress typical of industrial rectification tasks. It offers a balanced design for three-phase inputs, enabling lower ripple and reduced thermal stress compared with single-phase equivalents when used in matching systems. The component’s voltage and current ratings make it suitable for integration into medium-power assemblies where controlled DC supply and long-term reliability are necessary.
Suitable for
 Motor drive rectification in industrial control panels
 DC bus supply in power electronic converters and inverters
 Rectification stages in welding equipment and battery chargers
 Replacement or design-in for medium-power three-phase systems
Key specifications
 Configuration: three-phase bridge rectifier
 Maximum reverse (blocking) voltage: 1.6 kV
 Continuous forward current rating: 50 A
 Intended use: AC to DC conversion for three-phase inputs
 Typical applications: motor drives, power supplies, rectification stages
How to use
Install the rectifier in accordance with the system’s electrical diagrams and applicable safety standards. Ensure correct connection of the three AC input terminals and the positive and negative DC output terminals, respecting polarity. Provide adequate heat sinking and ventilation consistent with the device’s current rating and the ambient temperature of the installation to maintain junction temperature within safe limits. Verify compatibility with upstream protection devices (fuses, circuit breakers) and downstream loads before energizing.
Usage recommendations
For reliable operation, use this rectifier within its specified voltage and current limits, apply proper thermal management (sized heat sink or forced cooling) and confirm that surge protection and system grounding are in place. When integrating into motor drives or converters, perform insulation coordination and check that the device’s ratings match the expected peak and repetitive inverse voltages in the application.
