EMU-25 EMU-100 EMU-300 DESCRIPTION The EMU is a completely electronic unit. The following gives more details of this testing unit: • Complete computer control with its corresponding software and comunication 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). Please note: Due to the continuous research and development by EuroSMC, specifications in this catalog may be changed without previous notice. EMUCCEN - Version 2 • 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. FEATURES The EMU-100 can function as a single instrument or can be connected in parallel with others of its kind. When these units are connected in parallel, the current permitted is multiplied by the number of units connected. • All tests are made automatically, by software, with serial port RS-485.
