As standard EA devices are fitted with the most important digital and analog interfaces and ports, which are galvanically isolated. These include an analog interface which can be parameterized for input and output, control and monitoring, of 0 - 5 V or 0 - 10 V for voltage, current, power and resistance, assorted inputs and outputs, as well as USB and ethernet ports.
High-performance systems
High-power applications can be covered with high-power systems of up to 1920 kW. These are achieved by using the outputs of many PS 10000 devices, changing the copper rails to vertical, and connecting in parallel. Thus, a 19” cabinet with 42 U can provide a system with 240 kW occupying a 0.6 m² floorspace. The master/slave bus enables up to 8 cabinets with a maximum of 64 units of 30 kW each to behave as one unit.
Master-Slave-Bus and Share-Bus
If the integral master-slave bus and share bus are used, a multi-device system behaves as a single device. The master-slave bus and the shared bus are simply connected to each device. With the master-slave bus, the system data, such as total power and total current, are collected and shown in the master device. Warnings and alarms of the slave devices are shown clearly on display. The shared bus provides an equal load distribution to the individual devices.
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 the devices of the PS 10000 series with their 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.
On-board charger test
In an onboard charger test (OBC), the electrical features must be tested under various conditions. This requires a flexible test system that also provides test data. With the sequencing and logging functions of the PS 10000 devices, test procedures allow data to be exported and saved. In this way, applications can promptly 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 the test device, the control frequency of the power supply is adjustable. The modes Normal, Fast and Slow allow the PS 10000 devices to match the control characteristics of the onboard charger.
