Fixed voltage CV / fixed current CC / fixed resistance CR/fixed power CP four working modes. The series scales massively across models ranging from 150V environments up to an industrial 1200V scale, matching heavy duty capacities over 30KW and upwards of 1200A. Fits cleanly into standard 19-inch racks with varying chassis units.
