This description should clarify the voltage and current ranges available within the power hyperbole.

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 HE 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

A multi-device system behaves as a single device if the integral master-slave bus and share bus is used. The master-slave bus and the shared bus are connected to each device. With the master-slave bus, the system data, such as total power and current, are collected and shown in the controller device. Warnings and alarms of the agent devices are shown clearly on display. The shared bus provides an equal load distribution to the individual instruments.

Relay Test in the Production

Relay manufacturers must carry out various tests on their products during production. The coils and contacts are provided with precisely defined voltage and current. For the coil tests, essential parameters such as operating, holding, and decay current and the associated voltages must be checked and documented. The current carrying capability and contact resistance are crucial parameters for the contacts, and 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 precise, dynamic voltage, current, and power controls, 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.

Onboard 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. The sequencing and logging functions of the PS 10000 devices test procedures allow data to be read out and saved. 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.
