Informações:

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. • 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. For Indoor Use. • Simultaneous digital display of both voltage and current. • Automatic mode crossover into current or voltage mode. • Ten turn potentiometer voltage and current controls permit high resolution setting of the output voltage and current from zero to the rated output. • Flexible output configuration: multiple units can be connected in parallel or series to provide increased current or voltage. • High frequency switching technology allows high power density, providing increased power output in a small, light package. • Remote sensing to compensate for losses in power leads. • Adjustable Over-Voltage Protection (OVP) • External TTL, AC or DC shutdown • Remote voltage, resistive, current limit and OVP programming with selectable programming constants. • External indicator signals for remote monitoring of OVP status, local/remote programming status, thermal shutdown, and output voltage and current. • Optional IEEE-488 Interface for complete remote programming and readback capability.
