Elektro-Automatik EA-PS 10200-210 3U US208V DC Power Supply NEW

The Elektro-Automatik PS102002103UUS208V Single Output Programmable DC Laboratory Power Supply converts the energy from the grid into a regulated DC voltage with an efficiency approaching 100%. The PS 10200-210 3U US208V is able to be used with practically all global mains voltages. The DC voltage and current ratings are determined by typical applications. The DC supply operates as a flexible output stage with a constant power characteristic (auto ranging) and a wide voltage and current range.

To achieve higher power and current the PS 10200-210 3U US208V is equipped with a master-slave bus. This enables up to 64 parallel connected devices to be combined into one system. Such a system works as a single unit and can use different power classes, only the voltage class must remain constant. Furthermore, typical laboratory functionality is provided. This includes an extensive function generator, alarm and warning management, various optional industrial interfaces, software solutions, and many more functions.

The PS 10200-210 3U US208V is equipped with an active PFC which provides a high efficiency at a low energy consumption and can operate in a majority of global grids. It adjusts automatically, without additional configuration, to the available grid voltage.

The PS 10200-210 3U US208V features flexible output stages (auto ranging) and provides users with a wide voltage, current and power range, and hence a wider field of working than traditional power supplies.

Users can connect the PS 10200-210 3U US208V DC output via copper blades on the back side of the device. If a system with higher performance is required, the device is simply connected in parallel. With minimal effort, this unit can be linked with vertical copper rails.

"Auto ranging" is a term used when a programmable DC power supply automatically offers a wider output and input range of both voltage and current, in order to maintain full power across a wide operation range. This type of solution allows the use of a single unit to address multiple voltage and current combinations.

The PS 10200-210 3U US208V comes equipped with a function generator. This allows waveforms such as sine, triangle, square or trapezoid to be simply called up and applied to either the voltage or the current. A ramp function and a arbitrary generator allow voltage and current progression to be freely programmable. Test sequences for repeated tests can be saved and reloaded when needed, which saves time. For simulation of a photovoltaics system or fuel cells, adaptable tables are provided. With the integrated and adjustable PV characteristics curve DIN EN 50530 various solar modules can be defined, while entire day trend progressions can be simulated.

Conclusion: the user is supported by a multitude of useful functions features in the PS 10200-210 3U US208V.

As standard, PS 10200-210 3U US208V is fitted with the most important interfaces and ports - which are all galvanically isolated from the DC input. There is an analog interface which can be parameterized for input and output, control and monitoring - and for voltage, current, power and resistance, assorted inputs and outputs, and USB and Ethernet ports.

A 19 in. cabinet with a height of 42U can hold up to 12 units of 3U and thus form a system of up to 180 kW occupying only 0.6 m² (6.5 sq/ft) of floor space. The master/slave bus allows for up to 6 cabinets with a maximum of 64 units and up to 15 kW each to behave as one unit.

When the integrated master-slave bus and Share-Bus are used, a multi device system behaves as a single device - the buses are simply connected between each device. With the master-slave bus the system data, such as total power and total current, are collected and displayed on the master unit. Warnings and alarms of the slave devices are also clearly displayed. The Share-Bus works for a balanced load distribution between the individual units.

Applications

Relay test in the production: Relay manufacturers must carry out assorted tests on their products during production. For these the coils and contacts are provided with exactly defined voltage and current. For the coil tests, important parameters such as operating, holding and decay current, together with the associated voltages must be checked and documented. For the contacts, not only are the current carrying capability and contact resistance important parameters, but also voltage consistency and disconnect threshold indicate much about the product quality. Testing all these is best supported by an automatic test system. A part of such a system can be PS 10200-210 3U US208V with its exact, dynamic controls of voltage, current, power, and resistance, providing optimal values for the best test results. With their diverse interface connections, they can be integrated into any test system and deliver the necessary data without the need for additional measuring equipment.

Fuel cell simulation: The simulation of fuel cells allows for the optimal definition of energy storages, as well of the components powered by these fuel cells. In every application where reproducible data is required, the use of a simulator is typically a first choice. This is mainly due to the various built-in mechanisms for the protection of connected consumers. The overcurrent protection (OCP) can, like a safety fuse, switch off the output and generate an alarm. The voltage can be monitored and can, if over or under set limits, trigger various functions, as well as generate warnings and alarms. Thus, many integrated functions can be safely performed.

On-board charger test: In an on-board charger test (OBC) the electrical features of the charger must be tested under various conditions. This requires a flexible test system which also provides test data. The sequencing and logging functions of EA-Power Control software allows data to be exported and saved. In this way, applications can instantly generate reproducible test results based on dynamic and highly accurate set points and measurement data. To avoid competition between two separate control loops of the device under test (DUT) and the testing device, the voltage regulation speed of the power supply is adjustable. The modes Normal, Fast and Slow allow the PS 10200-210 3U US208V to be adapted to the control characteristics of the on-board charger.

Solar array simulation: The PS 10200-210 3U US208V programmable power supply is highly suited for use as test systems for PV inverters, because they can provide the necessary simulation for solar panels. Users can quickly access simulation models according to EN 50530 or Sandia to support diverse solar panel types. Parameters can include irradiation (varying with shadows), panel technology and temperature. Thus, the devices can test all the relevant electrical features of a PV inverter, including the important efficiency value. The high resolution of 16-bit technology and a high sampling rate enable this device to deliver accurate results, which can be documented and saved to an Excel file.
