Product Details

1336‑B003‑EJD is NEMA‑12 IP54 enclosed base‑model 3‑HP 460V 1336‑PLUS AC drive, not separate PCB boards. Suffix EJD stands for NEMA‑12 IP54 dust‑proof and oil‑tight cabinet. This is a bare base unit, without factory‑fitted HIM keypad and without any pre‑installed expansion option boards.

NEMA‑12 (IP54) housing provides protection against dust accumulation, dripping water and light oil mist; better environmental adaptability than NEMA‑1 (IP20), lower wash‑down capability compared with NEMA‑4 (IP56). It is widely deployed inside ordinary production workshops.

No local operator panel is fitted from factory. Users need to add external HIM unit (FA2 / FC3 etc.) for local parameter editing and manual operation. L‑series I/O, encoder feedback and S‑series communication option boards are all user‑installable accessories to be fitted into internal expansion slots on‑site.

Internal hardware integrates rectifier power stack, inverter IGBT power section, main control CPU board, auxiliary power supply, sampling and signal‑conditioning circuits. Supports sensorless vector and V/F control for standard three‑phase induction motors. Retains standard onboard analog/digital hard‑wired base I/O terminals for local hard‑wired start‑stop and speed reference.

Full protection suite: over‑current, over‑voltage, under‑voltage, over‑temperature, input phase‑loss, motor thermal overload, ground‑fault protection. Used for full‑unit replacement when multiple internal assemblies suffer compound damage. When swapping complete drive, back‑up original parameters, verify firmware compatibility and complete motor auto‑tuning. Strict ESD protection required during installation, commissioning and option‑board retrofitting. Signal cables should be shielded and routed separately from high‑power cables.

Typically applied for overhaul of legacy fans, pumps, general conveyors and workshop processing machinery; users select and add HIM and expansion options according to site actual control requirements.

Remark:Legacy EOL complete drive unit;original production discontinued;please confirm motor rating, site enclosure environmental requirement, input voltage, installation dimension, and list of required add‑on options before purchase.
