Resistors

The category resistors includes key electrical components responsible for regulating current in various bus systems. In 24V vehicles, resistors are essential for the proper operation of ventilation systems, LED lighting and engine accessory controls.

Bus resistors – Stabilisation and regulation of 24V systems

In a bus’s complex electrical system, resistors act as current regulators. They are used wherever it is necessary to reduce voltage or limit current in order to protect sensitive components or regulate their performance. At Peterbus.pl, we offer a wide range of resistors for buses from Solaris, MAN, Mercedes-Benz, Volvo and Scania.

Key applications of resistors in buses:

We supply components designed for specific vehicle functions:

• Blower and heater resistors: They provide multi-stage speed control for fans in the passenger compartment and driver’s cab. Their failure usually causes the blower to operate only at the highest speed.

• LED lighting resistors (CAN bus): They allow modern LED lighting to be installed in older vehicles, eliminating “burnt-out bulb” warnings on the dashboard by simulating the appropriate load.

• Radiator fan resistors: They enable the lower fan speeds to be switched on, helping to optimise engine temperature and reduce noise.

• CAN bus termination resistors: These are essential end-of-line components that prevent signal reflections and ensure reliable communication between control units.

• High-power wirewound resistors: Used in regenerative braking systems or as discharge resistors in hybrid buses.

Why choose Peterbus.pl resistors?

Resistors typically operate under a high thermal load, which in bus operating conditions (vibration and moisture) can cause them to crack or burn out. By choosing our products, you gain:

1. Thermal resistance: We offer resistors in ceramic or aluminium housings that dissipate heat effectively, ensuring a long service life.

2. Full compatibility with 24V systems: Our resistors are selected for the specific current parameters used in heavy-duty transport.

3. Selection by VIN: Blower resistors differ in resistance (Ω) and connector type. Our experts will precisely match the component to your model (e.g. Solaris Urbino, Mercedes Citaro).

4. New parts and tested replacements: We stock original resistors from brands such as Behr, Valeo and Hella, as well as high-quality replacement parts at attractive prices.
