Leviton 30 Amp 480V Locking Plug
The Leviton locking plug is designed for 480V three-phase applications, featuring a NEMA L16-30P configuration with 3P and 4W connections. Its black-white cord set and industrial grade build prioritize durable operation in demanding environments. One-piece contacts reduce friction and overheating, and the cord clamp accommodates a wide range of cord sizes for versatile installations. This option is suitable for temporary or permanent power hookups where a secure, weather-resistant connection is essential.
ATO 3HP 480V VFD Inverter
This 3HP 480V VFD from ATO provides three-phase input and a 2.2 kW output, delivering adjustable speed control for motors operating at 0–400 Hz. It supports 50/60 Hz inputs and operates with ±15% voltage tolerance, making it adaptable to fluctuating power conditions. Additional benefits include automatic energy-saving modes and automatic voltage regulation, designed to prevent nuisance trips by limiting running current and smoothing transitions during load changes. This drive is well-suited for spindle motors and general-purpose three-phase equipment requiring reliable speed control.
ATO 2HP 480V VFD Inverter
This 2HP VFD covers a broad input range up to 460V with 3-phase input and a 1.5 kW output. It offers an expansive output frequency range (0–1000 Hz) and adjustable frequency control, making it suitable for precise speed management of smaller three-phase motors in 480V systems. Automatic energy-saving features and automatic voltage regulation provide resilience against voltage fluctuations, reducing the risk of trips in marginal electrical environments. It is a practical choice for smaller equipment banks that still require robust VFD performance.
ATO 5HP 480V VFD Drive
The 5HP ATO VFD is designed for heavier loads, offering 3-phase input at 480V and an adjustable 0–400 Hz output. It includes protective features such as fault isolation and over-current/voltage protection, helping prevent nuisance trips during demanding operation. The IP20 enclosure enhances safety in indoor installations, and RS485 connectivity enables integration with automated control systems for centralized monitoring and control of motor speed and torque in industrial settings.
IBXDTUVJ 10 kW 480V→380V Transformer
This dry-type transformer converts 480V three-phase power to 380V with a 10 kW rating, suitable for facilities needing a stepping-down solution within a 3-phase network. Such transformers are robust, require minimal maintenance, and support steady-state applications like large drive systems or equipment that operates at 380V within a 480V supply environment. Proper integration involves ensuring correct grounding and compliance with enclosure ratings for your installation site.
Buying Guide for 480V 3-Phase Power Solutions
Key considerations when selecting a 480V 3-phase option include intended load, control strategy, and protection requirements. For motor drives, evaluate voltage tolerance, input frequency compatibility, and the ability to limit current to prevent nuisance trips. If your application demands secure outdoor or damp environments, prioritize IP ratings, rugged enclosures, and locking connectors to maintain safe operation. For transformers, verify the phase configuration and insulation class, along with cooling mechanisms for continuous operation in warm climates. When choosing a locking plug or connector, ensure the pin layout matches your equipment and that the device supports continuous duty in your facility. Finally, consider future scalability; some VFDs offer additional communications options for industrial networks, which can simplify integration with a centralized control system. Compare overall efficiency, control features, and maintenance requirements to identify the best fit for your 480V 3-phase needs.
