Automotive & Railway

Power amplifier especially for automotive applications

 

1. The flexible system LV124/148 in relation to:

— Switchable voltage ranges: 35V / 75V; Modulation either: unipolar / bipolar asymmetrical / bipolar symmetrical

— Power: 2kW … 24kW configurable in 2kW stages

— Also, several systems (typically 2) for the purpose of voltage increase or increase in current can be interconnected.

 

LV124, LV148 and related factory standards. Details under the heading "Newly launched".

 

2. The customized systems,

e.g. PA2014A for battery testing; PA3150A for the calibration of Hall sensors; PA2076 for on-board network simulation; PA2021F-FC for resonance determination of ICE railcars etc.
