SIEI Inverter Parts Catalog — 1. Brand & Product Overview

SIEI Inverter Parts Catalog — this page is the complete SIEI inverter parts catalog from One Elevator Co., Ltd., covering complete drives, control boards, power boards and encoder feedback cards with model numbers and compatibility notes. SIEI (Società Italiana Elettronica Industriale), known in the Chinese market as Xiwei (西威), is an Italian manufacturer of high-performance flux-vector frequency inverters (VFDs) widely used in elevator (lift) and escalator traction systems. The brand was later integrated into the Gefran drive portfolio. SIEI inverters are extensively applied in synchronous and asynchronous elevator drives — including Xizi Otis, Blink, Andis, and other major elevator OEMs — and are valued for their excellent price-to-performance ratio, built-in door-zone / early-open logic, brake feedback detection, and encoder auto-phasing.

This SIEI inverter parts catalog is supplied by One Elevator Co., Ltd. We stock genuine new SIEI inverter units and spare parts (control boards, drive boards, power boards, bases and PG / encoder feedback cards). The list below covers all SIEI inverter products currently offered on our website, organised by product family, with model numbers, functions and compatibility notes.

SIEI Inverter Parts Catalog — 2. Product Categories at a Glance

3. Category A — SIEI AVy-L Series Complete Inverters / Drives

Every AVy-L unit in this SIEI inverter parts catalog is a dedicated elevator flux-vector drive (Drive and Motion Control Unit). It controls both asynchronous (KBL) and synchronous (EBL) traction machines and is available from 5 kW to 30 kW. Suffix codes: EBL = synchronous motor version; KBL = asynchronous motor version; BR4 = built-in contactor / brake-relay option; AC4 = option code.

About the siei inverter parts catalog

Elevator and escalator control systems are built around a relatively small number of serviceable assemblies: the drive and motion controller, the main control or mother board, the power stage, the encoder feedback interface, and the door or brake control module. The siei inverter parts catalog is one of those assemblies, and like every board in the cabinet it is replaced on a different service interval. Each carries its own set of reference numbers depending on the original equipment manufacturer and the revision of the installation.

Every siei inverter parts catalog we supply is inspected before dispatch. Boards are checked for physical damage, capacitor condition and connector integrity, and are packed to survive international transit. Where a superseded revision is the only one available, we state that clearly and explain the substitution so that the installing engineer can make an informed decision.

Buying guidance and compatibility notes

Before ordering the siei inverter parts catalog, confirm three things. First, the exact part number and revision from the failed unit. Second, the equipment model and controller family it was installed in, since the same board can be used across several product lines. Third, whether the installation is a traction lift or an escalator, as the duty cycle and current rating differ between the two.

If you are unsure which revision of the siei inverter parts catalog you need, send a photograph of the nameplate and the existing board alongside the fault description. That is usually enough for our team to identify the correct replacement without a site visit, and it avoids the cost and delay of returning an incompatible part. We are also happy to advise on the other serviceable assemblies in the same controller, so that a planned shutdown can cover several wear items at once.
