EuroSMC EMU-300 Current Power Supply In ACThe EMU-300 is a completely electronic unit. The following gives more 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 a oscillating quartz and adjust this wave in 1024 point/cycle which insures the exact frequency and very low distortion.- The reference amplitude in d.c. 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 insure 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 (ex. auxiliary contact).- Synchronizes the output wave in phase and/or frequency with respect to external signals (external frequency/phase reference).- The unit contains an output overload, thermal, and auxiliary power supply alarms as well as a connector for an d.c. measuring instrument, for easy verification.APPLICATIONS- To test small circuit breakers.- Calibration of shunts and measurement instruments.- To test thermic relays which require a long duration.- Overheating test.CHARACTERISTICS- Regulation 0 - 300A a.c.- Nominal power: 300VA.- Can be connected in parallel.- Input for external phase and/or frecuency reference.- Computer controlled by serial port RS-485 (adapted to RS-232).- Overload, overheating alarm leds.- Rack mounting 19" (482 mm).- Accuracy: ±1%.- Distortion: <1%.
