System concept

EPOS 340 features four voltage signal sources and three current signal sources. The signal characteristics are computed by a high-performance signal processor and output via high-accuracy D/A converters and electronic power amplifiers. The amplitude, phase and frequency can be varied widely during output.

Signal sources

  • 4 independent voltage channels up to 300 V
  • 3 independent current channels up to 16 A
  • Synthetic signal generation
  • Wide frequency range
  • Freely selectable signal shapes
  • Play-back of transient signal characteristics
  • Generation of any flicker signal
  • High accuracy
  • Very low THD
  • Separate auxiliary power supply

Output of COMTRADE records & generation of any signal characteristic

The TRANSIG-monitor included in the scope of delivery can be used for the full graphical display and output of recorded signal characteristics which are available in standard COMTRADE format. During tests these signal characteristics are then “played back“ as transient signal waveforms by EPOS.

The TRANSIG-monitor also includes a signal editor which can be used to configure and calculate any signal characteristic. The signal characteristics can be generated from a basic function, such as a sine wave, with one or more superimposed functions, such as a direct component, exponential functions, harmonics, etc.

Programming interface

EPOS 340 also features a simple programming interface for special requirements, e.g. for use with test stands. This programming interface can be used in environments which support COM/ActiveX or in .NET environments.

The new TJCP Operator Interface

A new operating concept and extra powerful hardware make the EPOS 340 speedier than ever before. The system responds directly to user actions and can switch swiftly from one menu to another, all processes run smoothly.

The clear, restructured user interface guides the user quickly and intuitively to complete the task in hand. The individual screens are self-explanatory and uncluttered.

  • High-resolution, resistive 3.5“ touch screen
  • Ergonomic jog wheel for fast, easy setting
  • An illuminated ring and acoustic signals  indicate system status during settings and output
  • USB and Ethernet interface for direct connection to PCs and networks
  • Smart touch technology for easy operation
  • User actions, such as amplitude, phase angle  or frequency adjustments, are processed in
    real time and executed without delay
  • Settings can be selected from templates
