Maximum flexibility is achieved through a new housing concept – specifically designed for rolling stock. With integrated broadrange power supply and a unique combination of safety functions. Electric as well as diesel-electric locomotives and multiple units (EMU/DEMU) require multifold monitoring and control of electric energy. Voltage and current sensors used for this purpose need to meet the special demands posed by railway operations. Of particular concern are fire and smoke protection, electrical safety, as well as robustness towards extreme environmental conditions, mechanical stress and EMI influences. The P50000 transducer series was specifically designed for applications on locomotives and multiple units for short circuit recognition, monitoring and control of traction motors and converters, auxiliary converters, accumulator batteries and others. A brand new feature is the flexibility provided by switchable measuring ranges and an integrated broad-range power supply. Comprehensive certifications and conformity with railway standards make the devices the ideal choice for railway applications.

The P45000-series transducers are designed for measuring high DC and AC voltages on heavy vehicles, especially rolling stock. Application examples include the monitoring and control of traction motors or the monitoring of DC link voltage in traction power converters or on-board power converters.

The voltage measurement input is highly isolated from output and auxiliary power. The current output is compatible with commercially available control inputs.

The housing offers flexible mounting options: upright or horizontal, screwed or snapped onto 35 mm DIN rails. The devices can even be mounted in a stack, allowing for very tight space requirements.

For the first time, applications with functional safety requirements can be properly carried out. The high-voltage transmitter is certified for use in SIL2 systems and, redundantly, SIL3. Thus, for example, the presence of dangerously high voltages can be reliably detected.
