ZSLV PMLI ZSAC Electronic AC Loads, ZSAC Series Interface overview RS-232 USB GPIB LAN System bus Analog Analog isolated X Standard As single phase version and for 3-phase Star and delta connection possible Input voltages up to 440 V Power 400 W ... 21,000 W Current and resistance mode Programmable waveform Operating Modes Application Notes The AC current loads of the ZSAC series feature constant current and resistance operating modes. In AC mode the current is set as sinusoidal. In resistance mode the height and waveform of the current depends on the input voltage. Voltage Types Phase...
