What size phase converter do I need for my equipment?

Match the converter HP rating to the largest single motor you need to run. If running multiple machines simultaneously, size for the largest motor plus 50% of the additional motors' combined HP. For CNC machines with high inrush currents, we recommend sizing the converter at 2x the spindle motor HP. Call (800) 417-6568 for free sizing help from our engineers.

Can I run multiple three-phase machines from one phase converter?

Yes. One of the biggest advantages of a rotary phase converter is the ability to run multiple three-phase machines simultaneously. Connect the converter output to a three-phase sub-panel and run individual circuits to each machine. Size the converter for the largest motor plus 50% of all other motors running at the same time.

What is the warranty on Phoenix Phase Converters?

Every Phoenix Phase Converter comes with a lifetime warranty covering the control panel and all panel-mounted components for the life of the original owner. The generator motor carries comprehensive warranty coverage as well. We also provide free lifetime technical support — call (800) 417-6568 anytime.

Can this phase converter be installed outdoors?

Yes. All Phoenix Phase Converters use sealed NEMA-rated enclosures suitable for indoor or outdoor installation. The NL series uses NEMA 3R enclosures and the PL series uses NEMA 4 enclosures rated for harsh outdoor environments including dust, water jets, and extreme temperatures. Many customers install them in barns, outdoor shops, and agricultural settings.

How do I install a rotary phase converter?

Installation is straightforward for a licensed electrician: (1) Mount the converter near your panel, (2) Install the specified breaker size, (3) Run appropriately sized wire to the T1 and T2 input terminals, (4) Connect three-phase output to your equipment or sub-panel, (5) Power on and verify balanced voltage. Each converter includes a detailed installation manual with wiring diagrams. Call (800) 417-6568 for free installation support.

What is the difference between NL and PL series phase converters?

The NL series features digital smart controls with automatic voltage regulation and NEMA 3R enclosures for standard indoor/outdoor use. The PL series adds a built-in LED power monitoring panel with real-time status indicators for power, phase balance, and fault conditions, plus a heavier-duty NEMA 4 enclosure rated for harsh environments. Both series offer the same power quality and lifetime warranty.
