AC current source 1 - 120 mA, 3000 VA | CIS-3000

AC power supply

- Broad range of output currents - Broad range of allowable loads - High accuracy and stability - Low harmonic distortion - Multilevel protection system - Integrated Digital Signal Generator - Generation of harmonics The CIS-3000 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.
