Product Details

1336‑B003‑EAD is a full enclosed 3‑HP 460V‑class 1336‑PLUS constant‑torque AC drive, not a standalone PCB board. The EAD suffix stands for NEMA‑1 IP20 enclosed construction with factory‑fitted metal housing, no need for user‑provided outer cabinet for basic dust‑proof and touch‑safe protection.

Internally integrates rectifier power stack, inverter power section, main control CPU board, auxiliary power supply, analog/digital I/O interface and signal sampling circuits. Supports standard three‑phase induction motor control with both sensorless vector and V/F modes. It accepts analog speed reference, discrete start‑stop and interlock signals, and supports SCANport serial communication expansion.

Built‑in comprehensive protection functions: over‑current, over‑voltage, under‑voltage, over‑temperature, input phase‑loss, motor thermal overload and ground‑fault protection. Suitable for whole‑unit replacement when multiple internal assemblies suffer compound damage. When performing full‑unit swap, backup original parameters, verify firmware compatibility and complete motor auto‑tuning. Strict ESD protection required during installation and commissioning.

Commonly used for overhaul of legacy fans, pumps, conveyors and general‑purpose processing equipment.

Remark:Legacy EOL complete drive unit;original production discontinued;please confirm motor rating, input voltage and installation dimension before purchase.
