TELMA Control Units

Here is a professional, SEO-optimised category description for TELMA retarder control units (electromagnetic brakes), with a particular focus on older vehicles meeting the Euro 3 standard.

TELMA Control Units – Reliable Control of the Electromagnetic Brake (Retarder)

An electric retarder, commonly known in the industry as a Telma, is a key component of the safety system in every touring, intercity and city bus. It provides effective, contactless vehicle deceleration, which not only reduces the load on the conventional braking system but, above all, prevents discs and drums from overheating on long descents. The heart of this system is the TELMA control unit (control module), which precisely regulates the current supplied to the coils based on the signal from the steering-column lever or brake pedal.

A retarder control unit failure prevents the electric brake from being used, significantly reducing driving safety and accelerating brake-pad wear. At Peterbus.pl, we understand that a fully operational retarder is essential for safe operation, which is why we offer a wide selection of new and used TELMA control modules.

How to Choose the Right TELMA Control Unit

Control modules vary depending on the retarder generation, including manual, automatic and relay-based control units, as well as newer electronic modules operating with ABS/EBS. To avoid a mistake, it is worth recording the serial numbers from the rating plate of the old TELMA control unit before purchasing, or consulting our technical department.
