The CA Instruments 6000LS AC Power Source, 6000 VA is an improved version of the CA Instrument 6000L AC power source. It provides many basic AC source capabilities at an economical cost. Additional capabilities such as arbitrary waveform generation and harmonic measurements can be added as options. The 6000LS can be ordered in either single phase (-1) or three phase (- 3) configurations. Multiple chassis can be combined for power levels up to 18 kVA. The 6000LS is completely microprocessor controlled and can be operated from a simple front panel keypad. A pair of analog controls located next to the backlit alphanumeric LCD display allows output voltage and frequency to be slewed up or down dynamically. For more advanced operations, a series of menus is provided using a dual line high contrast LCD display.
