The microprocessor-controlled laboratory power supplies of series EA-PSI 9000 T offer a user-friendly, interactive handling concept, along with a extensive set of standard features, which can facilitate operating them. Configuration of output parameters, supervision features and other settings is smart and comfortable. The implemented supervision features for all output parameters can help to reduce test equipment and make it almost unnecessary to install external supervision hardware and software.
The clear control panel with its two knobs, one pushbutton, two LEDs and the touch panel with color display for all important values and status enables the user to handle the device easily with a few touches of a finger.

Display and control panel
Set values and actual values of output voltage, output current and output power are clearly represented on the graphic display. The color TFT screen is touch-sensitive and can be intuitively used to control all functions of the device with just a finger. Set values of voltage, current, power or the simulated, internal resistance can be adjusted using the rotary knobs or entered directly via a numeric pad. To prevent unintentional operations, all operation controls can be locked.

Autoranging power stage
All models are equipped with a flexible autoranging output stage which provides a higher output voltage at lower output current, or a higher output current at lower output voltage, always limited to the max. nominal output power. The maximum power set value is adjustable with these models. Therefore, a wide range of applications can already be covered by the use of just one unit.

Therefore, a wide range of applications can already be covered by the use of just one unit.

AC supply
The equipment uses an active Power Factor Correction (short: PFC), enabling worldwide use on a mains input from 90 VAC up to 264 VAC . Models with 1.5 kW will reduce their output power to 1 kW below input voltages of 150 VAC .

DC output
DC output voltages between 0...40 V and 0...750 V, output currents between 0...4 A and 0...60 A and output power ratings between 320 W and 0...1500 W are available. Current, voltage and power can thus be adjusted continuously between 0% and 100%, no matter if manually or remotely controlled (analog or digital). There is furthermore the resistance mode wich offers simulation of an internal in-line resistor. The output terminals are located on the front side of the devices.

Protective features
For protection of the equipment connected, it is possible to set an overvoltage protection threshold (OVP), as well as one for overcurrent (OCP) and overpower (OPP). As soon as one of these thresholds is reached for any reason, the DC output will be immediately shut off and a status signal will be generated on the display and via the interfaces. There is furthermore an overtemperature protection, which will shut off the DC output if the device overheats.

Remote Sensing
The standard sensing input can be connected directly to the load in order to compensate for voltage drops along with the cables. If the sensing input is connected to the load, the power supply will detect this and adjust the output voltage automatically to ensure the accurate required voltage is available at the load. The remote sensing connector is located on the front of the device.

Optional analog interface
A galvanically isolated analog interface can be installed optionally and subsequently, located on the rear of the device. it offers analog inputs to set voltage, current, power and resistance from 0...100% through control voltages of 0 V...10 V or 0 V...5 V. To monitor the output voltage and current there are analog outputs with 0 V...10 V or 0 V... 5V. Also, several inputs and outputs are available for controlling and monitoring the device status.

Display and control panel
Set values and actual values of output voltage, output current and output power are clearly represented on the graphic display. The color TFT screen is touch sensitive and can be intuitively used to control all functions of the device with just a finger tip. Set values of voltage, current, power or simulated, internal resistance can be adjusted using the rotary knobs or entered directly via a numeric pad. To prevent unintentional operations, all operation controls can be locked. The screen language can furthermore be selected between English, Russian, Chinese and German.

Function generator
All models within this series include a true function generator which can generate typical functions, and apply them to either the output voltage or the output current. The generator can be completely configured and controlled by using the touch panel on the front of the device or by remote control via one of the digital interfaces.
The predefined functions offer all necessary parameters to the user, such as Y offset, time/frequency or amplitude, for full configuration ability.
Additionally to standard functions, which are all based upon a so-called arbitrary generator, this base generator is accessible for the creation and execution of complex sets of functions, separated into up to 99 sequences. These can be used for testing purposes in development and production. The sequences can be loaded from and saved to a standard USB stick via the USB port on the front panel, making it easy to change between different test sequences.

Control software
Included with the device is a control software for Windows PC, which allows for the remote contrll of multiple identical or even different types of devices. It has clear interface for all set and actual values, a direct input mode for SCPI and BodBus RTU commands, a firmware update feature and the semi-automatic table control named "Sequencing". Optionally unlocked with a licence code, the app "Multi Control" can monitor and contrll up to 20 units at onlve and in one windows. The sequencing feature and data logging are here avaiblable as well
