AC SUPPLY
All models are provided with an active Power Factor Correction circuit and are designed for a usage on a three-phase supply with 340 V up to 460 V AC (models for the european market) or 188 V up to 229 V AC (US models).
POWER
The devices are 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 max. nominal output 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…1500 V, output currents between 0…20 A and 0…510 A and output power ratings of 0…3.3 kW, 0…5 kW, 0…6.6 kW, 0…10 kW or 0…15 kW are available. The output terminal is located in the rear panel.
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 visualised on a colour 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.
REMOTE SENSING
The standard sensing input can be connected directly to the load in order to compensate voltage drops along the power cables. If the sensing input is connected to the load, the power supply will adjust the output voltage automatically to ensure the required voltage is available at the load.
DIGITAL INTERFACES
All models features 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.
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…10 V or 0…5 V.
To monitor the output voltage and current, there are analog outputs with voltage ranges of 0…10 V or 0…5 V. Also, several status inputs and outputs are available.
OPTIONS
