14-Piece Wholesale Lot AC & Servo Drives

14-Piece Wholesale Lot: Industrial & Marine AC Variable Frequency & Servo Drives

This wholesale package consists of 14 high-reliability, multi-brand AC Variable Frequency Drives (VFDs) and AC Servo Amplifiers, selected for critical marine, offshore, and heavy industrial automation systems. Sourced from decommissioned vessel refits, industrial plant upgrades, and verified surplus reserve stocks, these units deliver precise velocity, torque, and position control for harsh operating environments.

Every unit in this lot features coated PCBs (conformal coating rated to standard IEC 60721-3-3 Class 3C2/3C3) for resistance against salt spray, airborne moisture, and cyclic thermal expansion typical in shipboard engine rooms and motor control centers (MCC).

Key Features

1. High-Torque Dynamic Vector Control: Closed-loop field-oriented control (FOC) and dynamic flux vector control for extreme load stability at near-zero shaft speeds.
2. Integrated Safety Functionality: Hardware-level Safe Torque Off (STO SIL 3 / PLe certified) on ABB, Schneider, Siemens, and Mitsubishi units for immediate torque disabling without disconnecting mains.
3. Industrial & Marine Fieldbus Protocols: Supports PROFIBUS DP, PROFINET, Modbus TCP/RTU, CANopen, and high-speed optical SSCNET III/H for multi-axis synchronization.
4. Conformal Coated Circuitry: Marine-treated electronic assemblies designed to withstand vibration (up to 1.0g per DNV rules), corrosive marine atmosphere, and 95% non-condensing relative humidity.
5. Universal Feedback Architecture: Interfaces natively with resolver, incremental ABZ encoder, absolute multi-turn encoders (EnDat 2.2, Hiperface, and 24-bit Mitsubishi high-resolution lines).
