The CIS-1600 Current Integrated Source was designed to be used as a reference alternating current source in the PS2 Power Sources of the electricity meter test equipment and in laboratories. The output current is isolated and independent of mains voltage.
The power stage of the source utilizes the Power Width Modulation (PWM) technology, which ensures high efficiency and thus contributes very small heat losses. The stage is driven by an onboard Digital Signal Generator. The control signal may be composed of harmonics of independently defined amplitudes and phases. The internal feedback loop utilizes the DSP technology. Advanced algorithms applied ensure high stability of amplitude and phase angle as well as low distortions of the output current over a full range of allowable loads of various characters.
A multilevel protection system implemented protects the source against overload, open circuit, overheat and makes operation of the device reliable and safe.
The CIS-1600 device is equipped with an isolated serial interface and can be operated by a PC or other controlling device (host). A number of sources can be synchronized and operated together to form a poly-phase system. The communication protocol is provided to control output settings as well as to access all internal registers.
The CIS-1600 Current Integrated Source is accommodated in a 19 inch plug-in case.
