Signal Generator EPOS 360
The multi-functional three-phase signal generator!
EPOS 360 is the multi-functional three-phase generator which comes into its own whenever maximum power and high signal accuracy are required. Intelligent amplifier technology and fully synthetic signal generation make it possible to issue any signal shape across a wide frequency range or even to play back complex transient signal characteristics.
EPOS 360 is designed for use as a stand-alone device or for operation with an external PC.
Electronic Power Sources
High-precision current and voltage sources are becoming more and more important in many areas of electrical engineering and especially in measuring and testing technology.
EPOS 360 is used wherever absolutely precise signals with a very low distortion factor, freely selectable signal forms and high power are required. EPOS 360 is therefore suitable for use in the testing, setting and calibration of power and power quality measuring instruments, disturbance recorders and electricity meters, among other things.
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.
EPOS 360 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 integrated operator interface
The internal operator interface is a special feature. Its highresolution 5“ touch screen with smart touch technology enables many signals can be output quickly and easily without having to connect an external PC.
The clear user interface guides the user intuitively to complete the task in hand. User actions carried out with the ergonomic jog wheel, such as amplitude, phase angle or frequency adjustments, are processed in real time and executed without delay.
An illuminated ring integrated in the jog wheel also provides information about current system status during settings and output. The states and operating modes of the inputs and outputs of the EPOS 360 are signaled via numerous LEDs in the control panel.
A quick glance is enough to see which outputs are active and which states are present at the binary inputs and outputs.
Precision measurement technology in different packaging
As standard, the EPOS 360 is built into a 19" rackmount housing. An optionally available portable housing makes the versatile signal generator suitable for stationary use in test benches, but also in the laboratory or for demanding outdoor applications.
EPOS 360 features four voltage signal sources and three current signal sources. The signal characteristics are computed by a highperformance signal processor and output via highaccuracy D/A converters and electronic power amplifiers.
The parameters amplitude, phase angle and frequency are separately and independently adjustable, as well as overload and short-circuit protected and can be varied over a wide range during output.
Voltage Sources EPOS CV
Single and three-phase voltage sources
Automatically regulated AC/DC voltage sources for single or three-phase voltages, with high power and fast settling time.
Automatically regulated voltage sources are used in many different test environments to supply power to components, motors and devices. The sources can be used to reproduce system conditions allowing the components to be tested to their limits under realistic conditions.
EPOS CV voltage sources are designed to output single or three-phase AC/DC voltages especially for high power values. The voltage sources provide excellent quality and sophisticated, practical functions and are ideal for use in laboratory or manufacturing environments.
Motor and Coil Test System EPOS MC4
EPOS MC4 - Motor and Coil Test System for Circuit Breaker Testing
EPOS MC4 is a compact, portable motor and coil test system with a particularly powerful AC/DC source.
EPOS MC4 is used to supply power to motors and trip coils and can be used as a battery substitute in switchgear and as a power supply during tests with ACTAS switchgear test systems.
The test system records the operating currents of spring winding and pump motors as well as trip coils and presents the numerical results of the motor and coil currents on the display.
Circuit breaker analysis
It is easy to analyse the results which can give a good indication of the state of coils, motors and mechanical parts or point to faults between windings.
Powerful voltage source
The newly developed voltage source uses state-of-the-art power electronics. Thanks to the synthetic generation of output quantities, the source is unaffected by disturbances in the power supply. This means that tests can always be carried out under identical conditions, allowing direct comparison of the results.
Unlimited output duration without cooling phases
The electronically regulated source of the EPOS MC4 is practically loss-less and generates very little heat, even at maximum output power. This means that high currents and voltages can be output for almost unlimited periods of time without cooling phases, resulting in significant savings in time and money in comparison with conventional systems.
For the motor current output, it is possible to limit high inrush currents, which can lead to the EPOS MC4 switching off, by means of a soft start.
A step-shaped ramp can be parameterized for the startup, which consists of a number of steps and a step time and increases from 0 to the nominal voltage value.
Simple and intuitive operation
For operation and control of the EPOS MC4, an operating unit with 5“ touch screen, jog wheel, function and trigger keys is integrated:
EPOS MC4 and ACTAS
EPOS MC4 is equipped with interfaces for connection to ACTAS test devices. Via the ACTAS test software, EPOS MC4 can be conveniently integrated as a source in switchgear tests. Automated test sequences and comprehensive analysis of test results are thus easily possible.
Measuring technology in robust packaging
EPOS MC4 is housed in a handy, extremely robust and resistant hard case. Waterproof and dustproof to IP67 when closed, the case absorbs even hard impacts without damage and reliably protects the test system‘s valuable electronics. And even the case lid has a special feature to offer. The cable compartment integrated into it offers sufficient space for the cable set supplied.
The robust test system is just as suitable for use on site as it is for use in production or in the laboratory.
Saving and evaluating test results
The test results are saved in the internal memory with a time and date stamp.
The data saved in the device can be downloaded and managed with the aid of a PC or laptop and the user-friendly EPOS MC4 software.
The measurement results can be presented in a report or exported to an Excel spreadsheet. It is also possible to save the test data in the software, ensuring that it can be made available for com-parison when future maintenance and servicing is required.
