EuroSMC EMU-100 MCB Testing Equipment

EUROSMC

The EMU-100 is a totally complete electronic unit. The following gives details of this testing unit.

  • Complete computer control with its corresponding software and communication board, RS-485. The program has the possibility to control up to 20 units at the same time.
  • The unit generates a digital wave form, from an oscillating quartz and adjusts this wave in 1024 point/cycle which insures the exact frequency and very low distortion.
  • The reference amplitude in DC and the selection by a DAC of 12 bits, allows a continued feedback, comparing the output level with the reference and activates a signal which controls the power amplifier, to ensure a perfect stabilized and accurate output, even though there are variations in the load, power supply etc.
  • The power module is compact, with forced ventilation and contains an auto power switch which gives the maximum power required in relation to the load. This achieves a very efficient output and low dissipation.
  • The transformer load coupled to the power amplifier, allows an galvanic insulation and perfect joining of this load.
  • Computer control of an external element up to 220V (external auxiliary contact).
  • Synchronizes the output wave in phase and/or frequency with respect to external signals (frequency/phase reference).
  • The unit contains an output overload, thermal, and auxiliary power supply alarms as well as a connector for a DC measuring instrument, for easy verification.
