Information:

DCS Series power supplies are 1000W supplies designed to provide highly stable, continuously variable output voltage and current for a broad range of development, system and burn-in applications. The series consists of ten models 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. The DCS Series employs high frequency switching regulator technology to achieve high power density and small package size. · Ten models with voltage ranges from 0-8 Vdc to 0-600 Vdc and current outputs from 1.7A to 125A. · 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. · Ten turn potentiometer voltage and current controls permit high resolution setting of the output voltage and current from zero to the rated output. · Automatic mode crossover into current or voltage mode. · 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.
