DCS Series power supplies are 1000W and 1200W supplies designed to provide highly stable, continuously variable output voltage and current for a broad range of development, system, and burn-in applications. The DCS Series employs high frequency switching regulator technology to achieve high power density and small package size. The series consists of twelve 1000W models and twelve 1200W models. The model numbers are designated by the DCS prefix, followed by the output voltage and current ratings. For example, the model number DCS 60-18E indicates that the unit is rated at 0-60 Vdc and 0-18 Amps while a model DCS 20-50E is rated at 0-20 Vdc and 0-50 Amps. 1.2 Operating Modes The DCS Series supply has two basic operating modes: Constant Voltage and Constant Current. In constant voltage mode the output voltage is regulated at the selected value while the output current varies with the load requirements. In constant current mode the output current is regulated at the selected value while output the voltage varies with the load requirements. An automatic crossover system enables the unit to switch operating modes in response to varying load requirements. If, for example, the unit is operating in voltage mode and the load current attempts to increase above the setting of the current control, the unit will switch automatically from voltage mode to current mode. If the load current is subsequently reduced below the setting of the current control the unit will return to voltage mode automatically. 1.3 Power Supply Features • Twelve 1kW models with voltage ranges from 0-8 Vdc to 0-600 Vdc and current outputs from 1.7A to 125A. • Twelve 1.2kW models with voltage ranges from 0-8 Vdc to 0-600 Vdc and current outputs from 2A to 140A. • 115/230 Vac selectable input voltage, 50-60 Hz single phase, Installation Category II.
