EPS Electric Power System.

An individual solution for you.

The modular system comprised of a generator, converter, and electrical consumers is easily adapted to the needs of each customer and thus to each vehicle category.

The overall system including safety devices is designed according to current standards.

The system components such as generators and the con-verters adapted to this purpose were developed in close partnership with renowned specialists, only Rosenbauer has access to these components.

Rosenbauer – EPS Electric Power System

Unique. Flexible. Powerful.

The Rosenbauer Electric Power System is the modern answer to the problem of more electrical power on the fire fighting truck. Rosenbauer offers the new EPS XS for installation near the engine and belt drive with power of up to 11 kVA as well as the EPX XL with cardan shaft drive from the PTO of the chassis with power of up to 90 kVA. Both systems enable new applications for supplying electricity to devices in use.

Benefits of the EPS Electric Power System.

▪ Direct, lossless, and variable speed drive of the generator

▪ Largely maintenance-free system due to the direct drive of the generator

▪ Parallel operation of pump and generator with high load at EPS XL possible

▪ Versatile applications (all electrical devices) ▪ Freedom of positioning of the devices on the vehicle ▪ Simple retrofitting of devices ▪ Operation via LCS display ▪ Satisfies DIN 14686 (EPS XL) and DIN 14687, supplemented by 400V (EPS XS)

▪ High safety through permanent insulation monitoring and IT network configuration

The EPS XL system is a high-performance generator system as an alternative to conventional built-in generators and large mobile units. It serves for the electrical drive of all consumers in the fire fighting truck with the exception of the centrifugal pump.

Installation in the vehicle The power generator with integrated rectifier is built into the chassis frame and driven directly by a PTO of the chassis by way of a cardan shaft. The converter and control box are flexibly positioned in the body. Additional sockets are flexibly installed in the body depending on the requirements. Sizes from 16 to 63 A are possible.

EPS Electric Power System – Rosenbauer

With the EPS XS, it is possible for the first time to produce three-phase 400 V AC voltage in a fire fighting truck by way of a direct motor using the power generator installed in the engine compartment. In contrast to conventional single-phase 230V systems, all heavy devices, such as submersible pumps, contaminated water pumps, etc. can be driven directly.

Installation in the engine compartment The EPS XS generator is built directly into the engine com-partment of the vehicle and driven by a belt. The converter and control box are flexibly positioned in the body. The position of the sockets can be selected according to the vehicle load.
