Lenze E82MV752-4B001 Frequency Inverter: Complete Technical Guide and Applications

14. januar 2026

Pre-shipment Inspection Record: This document details the visual and technical inspection of the Lenze E82MV752-4B001 Frequency Inverter: Complete Technical Guide and Applications. All product photos and testing videos below are original materials captured first-hand by the Koeed technical team in our warehouse prior to dispatch.

What is the Lenze E82MV752-4B board?

The E82MV752-4B is the main power board from a Lenze 8200 vector frequency inverter — the 5.5 kW, 400 V class drive, as the factory label states in shorthand: 02531788 0028, 82B 5.5KW400V MP3A37, serial 13167491. One correction to this listing's original title: what is photographed is the drive's internal board, not the complete inverter cabinet unit — it is the part you order when an 8200 vector of this size fails on its power stage or control electronics. The board carries twelve EPCOS 400 V DC-link capacitors, the gate-drive and control sections with two QFP processors, the switching power supply with its yellow Lenze transformer, and an on-board cooling fan. Second-hand removal, 2-month warranty as recorded at intake on 14 January 2026. All eleven photos and the inspection video show this exact board.

What this board does inside the drive

The 8200 vector's power stage and its brain share this one board. The twelve EPCOS snap-in capacitors are the DC link — the bank that smooths the rectified 400 V mains into the stiff bus the IGBT section chops into three-phase output, and on a 5.5 kW drive that bus holds enough stored energy to demand respect during any repair. The control half carries the processors that run the modulation and the drive's parameter set, the optocoupler-isolated gate drivers that bridge the control-to-power gap, and the switching supply — its yellow Lenze-marked transformer is visible mid-board — that powers everything from the bus. The X-series connectors around the edge are how the board mates to the rest of the chassis: control terminals, the display/keyboard, and the power terminals behind their clear protective shroud.

As a pull, the board photographs exactly as a service part should: the factory label with its barcode intact (02531788 0028, 82B 5.5KW400V MP3A37, 13167491), the E82MV752-4B revision-G silk legible, the fan and its bracket in place, and the reverse side showing the reinforced current rails and the N1200852 artwork marking. For a Lenze 8200 vector 5.5 kW/400 V drive that has lost its power stage, this is the board-level fix — the alternative being a complete drive replacement at several times the cost. The 2-month intake warranty covers a bench test window; verify the drive model matches before ordering, since the board is specific to this frame and rating.

Board with capacitor bank — The board in full: twelve EPCOS 400 V DC-link capacitors in three rows, the fan on its bracket, the yellow supply transformer, and the factory label with E82MV752-4B on the silk.

Factory label — The factory label close-up: 02531788 0028 / 82B 5.5KW400V MP3A37 / 13167491 — the rating shorthand that matches the 8200 vector 5.5 kW 400 V class.

Capacitor and fan detail — The DC link up close: the 400 V capacitor print, the fan in its metal bracket, and the yellow-wound supply transformer behind.

Power connector — The power connector behind its clear shroud, with the PE ground posts and the workshop inspection mark beside it.

Board silk and label — The board edge: E82MV752-4B and revision G on the silk, the X12B/X23B connectors and the PE6 post — the identity corner of the board.

Full board angled — Angled overview: the capacitor bank, the control section with its processors, the clear-shrouded power connector and the DIP switch block.

Label corner — The identity corner again: label, X10B/X23B connectors and the silk — shot for matching before ordering.

Rear component side — The opposite corner: D-SUB connector, fan, transformer and capacitor bank from the second angle.

Portrait overview: the whole board — control half up top with both QFP processors, power half below with the full capacitor bank, E82MV752-4B G along the edge.

Fan close-up — The fan close-up: the 4414-frame 12 V 0.30 A blower on its bracket — the board-level cooling the drive relies on.

Reverse side — The reverse side: the reinforced current rails, the N1200852 artwork marking and the three blue jumpers at the edge.
