Inverter Accessories, Modules & Spares

ACDC Drives stock a large range of spare parts, add on modules and accessories for the Inverters we supply. A lot of the modern drives are built in a modular format, thus allowing the user to add on modules to increase the functionality of the base drive at a later date, or to build exactly the right drive for the required application. We also keep a large range of accessories for the systems we design and install, so can provide more obscure parts to you on very short lead times.

Inverter Spares

We stock a wide range of spares for Inverter Drives and Motors. Often, the part required is a simple and cost effective way to keep you up and running, but isn't listed on the site, if this is the case, please call us, as we can often source these parts for you.  


SparesSpare parts on the shelf in our warehouse include, specialist fuses, replacement boards for the Inverters we sell, Line reactors, keypads, thyristors and many more useful spares.   

 Comms Modules

Many of the Inverters we sell are modular in design, meaning their functionality can be upgraded easily by just adding a simple card such as an Encoder feedback card or a MODBus Card.


Encoder card1

We stock the vast majority of these cards, enabling you to add to your drive quickly and easily. We can also advise on communications options, and on system design when contemplating these upgrades. 

 Inverter Accessories

Inverters and Motors are usually part of a larger system, this means you will need ancillary parts to get you up and running. We can provide all of these parts.

Encoder card1


At ACDC we stock a huge range of ancillary parts such as chokes, fuses, fuse holders, pot kits and many other useful parts. We aim to be the one stop shop for all things Motor and Drive related, so if you require extra parts but cant see them listed, call us and we will be more than happy to help and put together a quote for you.
