ATO 2hp 480V Three Phase VFD Inverter
Parameters indicate input 3 phase 240V/380V/460V options, but commonly used as a 480V system. Output is 1.5 kW with 0–input voltage range and a wide frequency range up to 1000 Hz. Best for light-duty spindle or tool tasks where space is at a premium.
Best for: small machines or accessory drives where compact size matters and torque demands are moderate. Caution: verify voltage compatibility with your mains before installation to avoid over-voltage trips.
ATO 10hp Three Phase VFD 480V
Provides 7.5 kW output with a 0–400 Hz range, suitable for larger spindle motors and machines requiring steadier speed control under load. Includes automatic energy-saving running and voltage regulation, with current limiting to avoid trips.
Best for: mid-to-large machines needing dependable speed control and protection features. Caution: ensure wiring and enclosure rating match your installation site for safe operation.
ATO 3 Phase 480V VFD 5.5 kW
Offers 5.5 kW output with 0–400 Hz range and automatic current control to reduce trip risk. Voltage regulation is included to handle fluctuations on 480V networks.
Better for: shop environments needing reliable performance at mid-range horsepower. Caution: check the motor nameplate HP and drive rating to ensure compatibility.
ATO 5hp 480V Three Phase VFD Enclosed
This 5 hp drive includes IP20 enclosure and RS485 connectivity, focusing on steady performance with protective features like current limiting and automatic voltage regulation. Output remains 0–input voltage with up to 400 Hz.
Best for: workshops needing an enclosed, ready-to-install option with communication capability. Caution: enclosure and installation must meet local electrical codes.
Buying Guide
What to consider when choosing a 480V three-phase VFD
- Horsepower and motor compatibility: match the VFD’s horsepower and current rating with your motor nameplate to avoid under- or over-sizing.
- Voltage range and supply: confirm your facility provides a stable 480V three-phase supply, and note optional input voltages listed in each model.
- Output frequency range: higher Hz ranges allow faster response but may impact motor cooling; ensure it meets your process needs.
- Protection features: look for automatic current limit, voltage regulation, fault protection, and anti-trip mechanisms to minimize downtime.
- Enclosure and environmental ratings: choose IP ratings and enclosure type matching your shop or manufacturing floor environment.
- Communication and integration: RS485 or other interfaces enable remote control and monitoring in automation systems.
- Physical footprint and cooling: larger HP drives may require dedicated cooling or space planning in cabinets or on benches.
