Description
The microprocessor-controlled laboratory power supplies of series EA-PS 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 set-tings 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, three LEDs and the touch panel with color display for all important values and status enable the user to handle the device easily with a few touches of a finger tip.
Features
- Wide AC supply voltage range: 90...264 V, with active PFC
- High efficiency: up to 92%
- Output power ratings: 0...320 W up to 0...1500 W
- Output voltages: 0...40 V up to 0...500 V
- Output currents: 0...4 A up to 0...60 A
- Flexible, power regulated output stage
- Supervisions and protections (OVP, OCP, OPP, OT)
- Intuitive touch panel with display for values, status and notifications
- USB port as standard, Ethernet & analog ports optional (all interfaces galvanically isolated)
- 40 V models compliant to SELV (EN 60950)
- SCPI command set and ModBus RTU support
- LabView VIs and control software for Windows
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.
Auto-ranging power stage
All models are equipped with a flexible auto-ranging output stage which provides a higher output voltage at low-er 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
DC output voltages between 0...40 V and 0...500 V, output currents between 0...4 A and 0...60 A and output power ratings between 0...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). The output terminals are located on the front side of the devices.
Discharge circuit
Models with a rated 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 sinks 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 on case the device overheats.
Remote sensing
The standard sensing input can be connected directly to the load in order to compensate voltage drops along 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.
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 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 0 V...10 V or 0 V...5 V. 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 represent-ed 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 or power 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.
Presetting of output values
To set output values without a direct impact on the output condition, the set values are also shown on the display, positioned below the actual values. With this, the user can preset required values for volt-age, current and power. It is either done by using the rotary knobs or by direct input on the touch panel. The five user profiles furthermore enable the user to switch easily between often used set values, just by activating a different user profile.
Control software
Included with the device is a control software for Windows PC, which allows for the remote control of multiple identical or even different types of devices. It has a clear interface for all set and actual values, a direct input mode for SCPI and ModBus RTU commands, a firmware update feature and the semi-automatic table control named “Sequencing”.
Optionally unlocked with a license code, the app “Multi Control” can monitor and control up to 20 units at once and in one windows. The sequencing feature and data logging are here available as well.
