PLT Series Phase Converters

Best For

Who uses the PLT Series?

The PLT Series targets shops and facilities that have 230V single-phase service and need to run 460V CNC machines or other voltage-sensitive three-phase equipment.

• 460V CNC machining centers — Haas, Mazak, Okuma, Doosan with 460V input
• 460V CNC lathes and turning centers
• Industrial servo presses — voltage-sensitive servo drives at 460V
• European industrial machinery — typically 400V, compatible with 460V output
• Large injection molding equipment with servo hydraulics

PLT vs NLT: What's Different?

Both convert 230V single-phase to 460V three-phase with a built-in transformer. The PLT adds enhanced output filtering:

• Tighter voltage balance — <2% imbalance for CNC requirements
• Reduced harmonic content on the generated third leg
• Better performance at variable loads — CNC machines constantly cycle

If your 460V equipment is standard industrial machinery (pumps, conveyors, non-CNC), the NLT Series is more economical. Use PLT for CNC and servo equipment.
