DC Power Supply
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.
