EA-PS 9000 2U Series
Power (P) Watt: 3000.00
Output voltages: 0…360 V
Output currents: 0…30 A
Flexible, power regulated output stage
Various protection circuits (OVP, OCP, OPP, OTP)
The Elektro EA-PS 9360-30 2U Programmable Laboratory DC Power Supply provides an output power rating of 0..3000 W with an output voltage of 0…360 V and an output current of 0…30A. It offers a wide AC supply voltage range: 90…264 V, with active PFC.
This microprocessor-controlled laboratory power supply comes with a clearly arranged control panel that features two rotary knobs, six pushbuttons, and two LEDs. Together with a color TFT display for all values and status, it simplifies the use of the device.
AC supply
This unit is provided with an active Power Factor Correction circuit and models up to 1.5 kW are even suitable for a worldwide operation on a supply from 90 V AC up to 264 V AC. With the 1.5 kW models, the output power is automatically reduced to 1 kW if the supply voltage is <150 V AC and with the 3 kW models is reduced to 2.5 kW at <205 V AC.
Power
This unit is equipped with a flexible auto-ranging 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 adjustable power set value or the rated power. Therefore, a wide range of applications can already be covered by the use of just one unit.
DC output
This model offers a DC output voltage of 0...360 V, an output current of 0...30 A, and an output power rating of 0...3000 W.
Current, voltage and power can be adjusted continuously between 0% and 100%, no matter if manually or remotely controlled (analog or digital). The DC output is located on the rear panel of the devices.
Discharge circuit
Models with a nominal output voltage of 200 V or higher include a discharge circuit for the output capacities. For no load or low load situations, it ensures that the dangerous output voltage can sink to under 60 V DC after the DC output has been switched off. This value is considered as limit for voltages dangerous to human safety.
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.
Display and controls
All important information is clearly visualized on a color TFT display. With this, information about the actual output values and set values of voltage and current, the actual control state (CV, CC, CP) and other statuses, as well as alarms and settings of the setup menu are clearly displayed.
In order to ease adjusting of values by the rotary knobs, pushing them can switch between decimal positions of a value. All these features contribute to an operator friendliness.
With a panel lock feature, the whole panel can be locked in order to protect the equipment and the loads from unintentional misuse.
Analog interface
There is a galvanically isolated analog interface terminal, located on the rear of the device. It offers analog inputs to set voltage, current and power 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 voltage ranges of 0 V...10 V or 0 V...5 V. Also, several inputs and outputs are available for controlling and monitoring the device status.
Digital interfaces
All EA-PS 9000 2U models feature two galvanically isolated, digital interfaces by default (standard: 1x USB & 1x Ethernet, with option 3W: 1x USB & 1x GPIB), which are located on the rear side. USB and Ethernet can be used to control and monitor the devices either with SCPI language commands or ModBus RTU protocol, while with GPIB only SCPI is supported.
Software and programming
For remote control from a Windows PC, there is a software EA Power Control included with the device. It can be used with multiple different or identical models of series EA-PS 9000 2U to monitor and control the units. The software furthermore includes a firmware update tool, as well as a feature to record data and to control the units by a semi-automatic table processing.
For even more sophisticated, customer-specific applications there is complete programming documentation and also LabView VIs for direct implementation available.
All models of series EA-PS 9000 2U support the common command language SCPI and the ModBus RTU protocol via Ethernet and USB. Models with option 3W can only use SCPI via the GPIB port.
Remote sensing
Remote sensing can be done via a dedicated input which is directly connected to the load equipment, in order to compensate voltage drops along with the load cables. The power supply detects automatically whether the sensing input is connected and will stabilize the voltage directly at the load. The connection for the remote sensing is located on the rear of the device.
Options
Three-way interface (3W) with a rigid GPIB port installed instead of the default Ethernet port.
