The Elektro-Automatik PS 10500-60 3U Single Output Programmable DC Power Supply, 500V/60A, 10000W, 3U Rack converts the energy from the grid into a regulated DC voltage with an efficiency of up to 96%. The DC voltage and current are directed by the application and the spectrum ranges in this single device. The DC supply operates as a flexible output stage with a constant power characteristic (auto-ranging) and a wide voltage, current and power range. To achieve higher power and current this unit 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 industrial interfaces, software solutions, and more.

The EA-PS 10500-60 3U is equipped with an active PFC which provides a high efficiency at a low energy consumption, while providing a wide input voltage range. This devices can be operated in the majority of global grids. It adjust automatically, without additional configuration, to the available grid voltage.

The DC output of the PS 10500-60 3U has flexible output stages (auto-ranging) that provide users with a wide voltage, current and power range - a wider field of work is possible, than with traditional power supplies. "Auto-ranging" is a term used when a programmable DC power supply automatically offers a wider output range of both voltage and current, 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.

Connection of the DC output is done via copper blades on the back side of the PS 10500-60 3U. With minimal effort these devices can be linked with the vertical copper rails; a cover is included to protect the contact.

As standard, the PS 10500-60 3U 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, voltage, current, power and resistance, assorted inputs and outputs, as well as USB and Ethernet ports.

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 (PS 10500-60 3U). Warnings and alarms of the slave devices (not included) will also clearly display on the master unit (PS 10500-60 3U).

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 of these is best supported by an automatic test system. A PS 10500-60 3U can be a part of such a system with its exact, dynamic controls of voltage, current, power, and resistance, providing optimal values for the best test results. With its diverse interface connections, the PS 10500-60 3U can be integrated into any test system and deliver the necessary data without the need for additional measuring equipment.

During an on-board charger test (OBC), the electrical features must be tested under various conditions. This requires a flexible test system which also provides test data. With the sequencing and logging functions of the included EA Power Control software, data can be exported and saved. In this way, applications can instantly generate reproducible test results based on dynamic and highly accurate set point and measurement data. To avoid competition between two separate control loops of the device under test (DUT) and testing device, the voltage regulation speed of PS 10500-60 3U bidirectional power supply is adjustable. The modes Normal/Fast/Slow allow the power supply to adapt to the control characteristics of the on-board charger.
