1、 DCS-E 1kW Series all circuits and/or terminals to be touched must be safety grounded to the chassis. After the unit has been operating for some time, the metal near the rear of the unit may be hot enough to cause injury. Let the unit cool before handling. Qualified service personnel need to be awar

2、e that some heat sinks are not at ground, but at high potential. These operating instructions form an integral part of the equipment and must be available to the operating personnel at all times. All the safety instructions and advice notes are to be followed. Neither Sorensen, San Diego, California

3、, USA, nor any of the subsidiary sales organizations can accept any responsibility for personal, material or consequential injury, loss or damage that results from improper use of the equipment and accessories. i RadioFans.CN 收音机爱 好者资料库 SAFETY SYMBOLS ii SORENSEN FIVEYEAR WARRANTY Sorensen, a divisi

25、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 de

26、nsity 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 Amp

27、s while a model DCS 20-50E is rated at 0-20 Vdc and 0-50 Amps. 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 requ

28、irements. 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 operati

29、ng 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 autom

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, I
