System description

Circuit breaker analysis

EPOS MC3 also provides a number of further functions for circuit breaker analysis:

  1. Analysis of motor and coil operation
  2. Determination of the coil resistance
  3. Determination of the minimum operating voltage
  4. Tests for undervoltage releases

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.

New, 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.

  1. Variable test voltages with high voltage stability up to 270 VAC / 300 VDC
  2. Maximum currents up to 40 amperes
  3. Two outputs for opening/closing coils, one output for the motor
  4. Outputs are independently configurable with regard to voltage and frequency
  5. Short-circuit proof and overload-protected

Unlimited output duration without cooling phases

The electronically regulated source of the EPOS MC3 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.

Simple and intuitive operation

EPOS MC3 features an integrated control panel with a 3½“ touch screen and 7 function keys for operating and controlling the device:

  1. All settings are clearly displayed
  2. Test parameters can be edited directly
  3. Display of output values
  4. Additional display of operational status via LEDs

A remote control unit is available as an optional extra for controlling the motor and coil outputs.

System versatility

The built-in control panel, light weight and low noise level make this robust test system equally suitable for use on site, on the shop floor, or in the lab. All the connections are located on the front panel so the test system can also be operated in an upright position.

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 MC3 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 comparison when future maintenance and servicing is required.
