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 •Analysis of motor and coil operation •Determination of the coil resistance •Determination of the minimum operating voltage •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. EPOS MC4 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.
