PH Series Phase Converters

Important

Do you have 460V single-phase service?

The PH Series requires 460V single-phase input — less common than 230V service. This is typically found at rural industrial properties, large farms, or facilities served by high-voltage utility drops. Most shops and residential locations have 230V service. If you have 230V service and need 460V output, use the PLT Series instead.

PH vs NH: What's Different?

Both series convert 460V single-phase to 460V three-phase. The PH adds enhanced output filtering:

• Enhanced capacitor bank — maintains <2% voltage imbalance for sensitive loads
• Reduced harmonic content on the generated leg
• Better performance under variable CNC loads

For standard industrial motors (pumps, compressors, conveyors) on 460V service, the NH Series is sufficient. Use PH for CNC and servo equipment.
