Single and Three Phase AC Power Supplies up to 1MW: The DF-C Series

The ARM microcontroller controlled single-phase and three-phase alternating current power supplies of the DF-C series ranging from 500 Watts to 1 Megawatt offer a variable true-sine output with precisely adjustable phase voltage and frequency. These powerful AC laboratory power supplies have been developed for laboratory and industrial use and can be operated continuously without maintenance even under maximum load. Optionally, DF-C series AC power supplies can be equipped with digital and analogue inputs and outputs, the advanced ARM control provides very stable output values ​​and fast response times. In the basic version, these AC laboratory power supplies offer the operating mode CV (constant voltage) and easy-to-read high-resolution voltage and current displays. Also versions with CC (constant current) mode can be made on request. All parameters can be easily set via the front panel or via the optional analog or digital connections. Automatic protection functions integrated in the AC laboratory power supply allow safe operation in all conditions, the output is short-circuit proof and earth-free. Special designs with frequencies up to 400Hz and phase voltages up to 1,100V sine peak-to-peak are possible.
