SECTION 1. FEATURES AND SPECIFICATIONS
1.1 Description
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.
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
• 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.
