RARE Elgar 751SL 751 SL AC Power Source / Supply Model#- 751SL-11 Signal Routing Plug-In Series 400 This is a decent unit here. This came from a working environment. (have not tested this, as I don't have the right connection). Unit is solid and will work, but certainly may need calibrations/fine tuning. terminal blocks appear to be damaged and may need repaired. From manufacture: AC Power Source AC Output Power 750 VA Voltage Range 0 Vrms 260 Vrms Voltage Regulation 1% Frequency Range 45 Hz 5 kHz Frequency Regulation N/A Controler Not included Input Power 120 1 PH UPDATE on listing - It has been brought to my attention that the unit I am selling here is one part of a 3 phase system that is needed to generate power. AGAIN - this unit is the Signal Routing unit. You will at least need an oscillation module with this. Thanks We will ship this for free. Yes FREE!!! Will ship international. Please ask Questions
