ATV71HD18N4
Schneider Electric
Overview
The ATV71HD18N4 is a Variable speed drive in the Altivar 71 range from Schneider Electric. It controls AC motors from a 380...480 V - 15...10 % supply and is configured through the Altivar parameter set.
Application & Technical Notes
As a variable speed drive, the ATV71HD18N4 is intended for deployment in panel-based control cabinets and machine enclosures where Altivar variable speed drive equipment is installed. It regulates the speed, torque and position of an AC motor to match the process demand while protecting the mechanical train.
Key published characteristics include a 380...480 V - 15...10 % rating, an operating temperature range of 14…122 °F (-10…50 °C) (without derating). These values should be confirmed against the current manufacturer datasheet before final selection, as options and suffixes vary by configuration.
Maintenance & Diagnostics
Respect the published operating temperature window (14…122 °F (-10…50 °C) (without derating)); do not exceed it during commissioning or in enclosed panels without airflow. For storage and transit, keep the unit within -13…158 °F (-25…70 °C). Avoid condensation — the rated humidity is 5…95 % without condensation IEC 60068-2-3; store and operate the module in a dry, pollution-degree-appropriate enclosure. Maintain clearances for cooling, back up the motor parameter file, and verify the thermal setting matches the driven load. Always de-energise the circuit and follow lock-out/tag-out before handling; refer to the official instruction bulletin for service procedures.
Sourcing & Procurement
When sourcing the ATV71HD18N4, distinguish three supply tiers: (1) genuine Schneider Electric stock from an authorised distributor; (2) compatible equivalents or surplus/NOS (new-old-stock) from third parties; (3) alternative parts offering equivalent function. Genuine supply carries the full warranty and traceability; compatible or alternative items may be cheaper but should be validated for form, fit, firmware and certification before use in a live system. PLCXpert publishes this page as an independent reference and does not sell the part — verify every claim with the manufacturer or your distributor.
Match the drive rating, supply voltage and motor parameters, and confirm the option cards and communication profile required by the application. Lead times and pricing vary by region and lifecycle status; obtain a current quote from an authorised channel rather than relying on stale listings.
