Phase Converters

How Rotary Phase Converters Work?

Rotary Phase Converters are devices used to generate three-phase power from a single-phase power source. They operate by using a single-phase input voltage and converting it into three-phase output voltage through the use of a rotating converter. The converter consists of capacitors and a specially designed generator that mimics the third phase.

Types of Rotary Phase Converter Offered By Bruce Electric

Bruce Electric Equipment Corp. offers one of the comprehensive collections of industrial rotary phase converter for sale.

• MA (Manual Activation): Type MA rotary phase converters are manually activated devices that use a single-phase motor coupled with capacitors to produce the third phase. They require manual activation, typically through a switch or control panel, to start generating three-phase power.
• MA-A (Manual Activation with Automatic Restart): Type MA-A rotary phase converters combine manual activation with automatic restart functionality. This means that in the event of a power outage or interruption, the converter can automatically restart once power is restored, without requiring manual intervention
• DP-A (Digital Phase Converter with Automatic Restart): Type DP-A rotary phase converters utilize digital control systems for precise generation of three-phase power. They often include features like automatic restart, soft-start capabilities, and advanced monitoring functions. The digital control allows for more accurate output and better efficiency compared to manual systems.
• DP (Digital Phase Converter): Type DP rotary phase converters are similar to DP-A converters but may lack the automatic restart feature. They still utilize digital control systems for precise generation of three-phase power and may offer features like soft-start and advanced monitoring.
• PI (Power Integrator): Type PI rotary phase converters are designed to integrate seamlessly with existing power systems. They often incorporate features like power factor correction and harmonic filtering to improve efficiency and reduce electrical noise.

Technical Specifications

• Horsepower (HP): The Rotary Phase Converter is available in a variety of horsepower ratings to meet the requirements of different equipment. This includes 5HP, 7.5HP, 10HP, 20HP, 25HP, 30HP, 40HP, up to 100HP.
• Single Phase Input Voltage: Typically operates with standard single-phase input voltages, such as 120V or 240V AC.
• Output Voltage: Generates three-phase output voltages suitable for powering three-phase equipment.
