Buy Phase Converters for Industrial and Shop Equipment
Find phase converters, rotary phase converters, static phase converters, CNC phase converters and related signal conversion products at Selectum LLC. A phase converter is commonly used as a single phase to 3 phase converter when equipment requires three-phase power but only single-phase power is available. This category includes Phase-A-Matic static phase converters, rotary phase converters, CNC PAC phase converters, WeatherPhase models and selected high-voltage or 400V options, in ratings from 1/3 HP up to 100 HP. It also includes PCE Instruments signal converters and measuring transducers for compatible process control and automation applications. Explore the catalog to find a phase converter or signal conversion product that matches your voltage, horsepower, load type and installation requirements.
Applications and Uses for Phase Converters
Phase converters are used in machine shops, manufacturing facilities, farms, workshops, maintenance departments and other environments where three-phase equipment needs to operate from available single-phase power. They may support motors used with machine tools, pumps, compressors, woodworking equipment, metalworking machines, CNC equipment or other compatible industrial loads. PCE signal converters in this category serve a different purpose and are used for converting or transmitting electrical measurement signals in automation and control systems. Each product should be selected according to the equipment type, motor load, voltage, horsepower or kilowatt rating and installation conditions.
Products in this category
This category offers several types of phase conversion and signal conversion products for different applications:
- Static phase converters for selected three-phase motor starting and light-to-moderate duty applications, in heavy-duty UL and PAM series ratings
- Rotary phase converters for compatible equipment that requires more balanced three-phase power
- CNC PAC phase converters for selected CNC and electronically controlled equipment applications
- RWP Series WeatherPhase rotary phase converters for compatible outdoor-oriented installations
- Phase converter models in different horsepower, kilowatt and voltage configurations, including 230V, 460V and selected 400V options
- UL Certified models available on selected Phase-A-Matic static and rotary phase converters
- PCE Instruments universal signal converters and measuring transducers, including DIN rail mountable models, for compatible process control and automation systems
- Products from Phase-A-Matic and PCE Instruments
Converter types and performance
Phase converter performance depends on the converter type, motor horsepower, load characteristics, voltage, starting requirements and installation environment. Static converters are often selected for simpler motor-starting applications, while rotary converters are commonly used where equipment benefits from steadier three-phase power. CNC PAC models are designed for selected CNC and electronically controlled equipment applications, while WeatherPhase models are listed for compatible outdoor-oriented installations. For PCE signal converters, performance depends on the supported input signal, output signal, measuring range and mounting requirements. Always review the product specifications before ordering to confirm compatibility with your equipment and electrical system.
Specifications and selection guide
Choosing the right phase converter starts with the machine or motor you need to operate. Confirm the motor horsepower or kilowatt rating, required voltage, load type, starting demand, duty cycle and whether the equipment includes sensitive electronics or CNC controls. Then decide whether a static, rotary, CNC PAC or WeatherPhase model is appropriate for the installation. For signal converters and measuring transducers, check the input range, output signal, mounting style and control system requirements. Since this category includes multiple product types across several pages, filtering by brand, converter type, voltage and horsepower or kilowatt rating can help narrow the selection.
Complete your setup
Plan the installation with compatible wiring, disconnects, motor protection, controls, mounting hardware and electrical enclosures, following the equipment manufacturer's requirements and applicable electrical codes. Qualified electrical support may be needed for sizing and installation. For measurement and control instrumentation rather than motor power conversion, Selectum also carries process control sensors.
Why shop Phase Converters at Selectum LLC
Selectum carries the Phase-A-Matic range of static, rotary, CNC PAC and RWP WeatherPhase converters covering 1/3 HP through 100 HP, with UL Certified options across the static and rotary lines, alongside PCE Instruments signal converters and measuring transducers. Product pages list brand, model, voltage and horsepower or kilowatt rating with pricing and shipping details, so you can match a converter to your machine before ordering.
Frequently Asked Questions
How do I choose the right size phase converter?
Start with the motor horsepower or kilowatt rating of the equipment you need to run, then check the starting load, duty cycle and voltage requirements. Some machines require a converter sized above the motor nameplate rating, especially when the equipment has heavy starting loads or multiple motors. Always compare the product specifications with the equipment manufacturer's requirements before ordering.
What is the difference between a static and rotary phase converter?
A static phase converter helps start and run selected three-phase motors from single-phase power, but it may not provide the same balance as a rotary phase converter. A rotary phase converter uses an idler motor to generate three-phase power and is often selected for equipment that needs steadier operation. The better choice depends on the machine, motor load, duty cycle and power quality requirements.
When should I choose a CNC PAC phase converter?
A CNC PAC phase converter should be considered when the equipment includes CNC controls or sensitive electronics and the product is specified for that type of use. CNC equipment may have different power quality and starting requirements than a basic motor load, so check the machine documentation and converter specifications carefully.
Does voltage matter when buying a phase converter?
Yes. Phase converters are voltage-specific, so you need to match the converter to the available input power and the equipment's required output voltage. This category includes models listed with voltage options such as 230V, 460V and selected 400V configurations, but compatibility depends on the exact product and installation.
Can I use a phase converter outdoors?
Some WeatherPhase or outdoor-oriented models may be suitable for compatible outdoor installations, but not every phase converter is designed for weather exposure. Check the product specifications, enclosure details and installation requirements before using a converter outdoors or in a harsh environment.
Are PCE Instruments signal converters the same as phase converters?
No. PCE Instruments signal converters and measuring transducers are used for electrical signal conversion or measurement transmission in automation and control systems. They are not the same as Phase-A-Matic phase converters used to run three-phase equipment from single-phase power. Choose the product type based on whether you need motor power conversion or signal conversion.
