General The microprocessor controlled laboratory power supplies of series EA-PS

8000 T cover state-of-the-art technology. They already offer many functions and features in their standard version, making the use of this equipment remarkably easy and most effective. The units are provided with a memory function for five diffe- rent preset values, with the ability to save and recall these just by the push of a button. Thus frequently used settings are at immediate reach to the user. Input The equipment uses an active Power Factor Correction circuit to enable using it worldwide on a mains input from 90V up to 264V AC. * Models from 1kW * 针对1kW以上型号 日期 / Date: 05.01.12 本公司保留对本目录书出现的错误进行修改或删除的权利,且不另行通知 / Subject to modification without notice, errors and omissions excepted 所有参数为典型值 / All values are typical values Power Models from 1kW output power are equipped with a flexi- ble, auto-ranging output stage. It provides a higher output voltage at lower output current or a higher output current at lower output voltage, always limited the max. nominal output power. Therefore, a wide range of applications can already be covered by the use of just one single unit. Units with 1.5kW are derated, i.e. reduced to 1kW max. power at input voltages below 150VAC. DC output Output voltages between 0...16V and 0...360V, output cur- rents between 0...4A and 0...60A and output power ratings between 320W and 1500W are available. The output terminals are located in the front panel. Overvoltage protection (OVP) In order to protect the connected loads it is possible to adjust an overvoltage protection threshold (OVP). If the output voltage exceeds the adjusted limit, the output is shut down and status signals via a LED and via the analogue interface will be generated. Remote sense Remote sensing can be done via a dedicated input which is directly connected to the load equipment, in order to com- pensate voltage drops on the load cables. The power supply detects automatically whether the sense input is connected and will stabilise the voltage directly at the load. The remote sensing input terminal is located on the front panel. Displays and controls Output voltage and current are clearly visualised on two 4-digit displays. The functional status of the unit and its buttons are indicated via LEDs, providing easier and most comfortable handling to the user. Output voltage, current and OVP values can be set by two rotary knobs. A fine setting mode for high resolution adjust- ment is provided as well. With the LOCK mode, buttons and knobs can be locked to prevent unintentional change of settings. The main power switch is located on the back panel, an output shutdown button is on the front panel. Presetting of output values To set output values without affecting the output condition, a preset function is implemented. With this function the user can preset values for the output voltage, output current and overvoltage protection (OVP). Analogue interface The connection for the analogue interface is located on the front of the device. It offers analogue inputs to set voltage and current from 0...100% in the voltage range of either 0V...10V or 0V...5V. This is selectable in the device setup. To monitor output voltage and current, analogue outputs with voltage ranges from 0V...10V or 0V...5V can be read out. Furthermore, several inputs and outputs are available for controlling and monitoring the device status. There is no galvanic isolation with this interface. EA-PS
