The bidirectional DC laboratory power supplies of the EA Elektro-Automatik PSB 10000 series are two-quadrant power supply units that can take on the function of both a power supply and an electronic load. In load operation, the DC power supplies work regeneratively and feed the energy back into the local power grid with an efficiency of over 96%. This efficient energy recovery reduces your costs.
The EA PSB 10000 series includes single-phase and three-phase devices that can serve almost all mains voltages worldwide thanks to their wide input range. The DC voltages and currents are geared towards applications, the spectrum ranges from 0 - 10 V to 0 - 2000 V and from 0 - 6 A to 0 - 1000 A in one device. The DC power supplies function as a flexible output stage with a constant power characteristic, so-called autoranging, as well as a wide voltage, current and power range. All devices have a master-slave bus to realize higher power and currents. With 64 devices connected in parallel, this enables a system to be set up that provides up to 1920 kW and 64,000 A.
All models in the PSB 10000 series have an integrated function generator. This can be used to easily call up curves such as sine, triangle, rectangle and trapezoid. Voltage and current curves can be freely programmed using a ramp function and an arbitrary waveform generator. Test sequences can be saved for recurring tests and reloaded as required, saving valuable time.
Typical applications for bidirectional power supply units include testing the electrical properties of a battery. The wide range of applications includes cell, module or pack tests, determining the SOH (State-Of-Health) for a second-life classification and the end-of-line test (EOL). Other applications include the simulation of batteries as individual cells, modules or in packs. With the help of these simulations, both the energy storage system and the components that are supplied by it can be optimally designed. The DC power supply units in the PSB 10000 series can also be used to test the electrical properties of fuel cells, fuel cell stacks and fuel cell systems. They generate highly accurate and reproducible results in all electrical modes. To test the resistance, performance and service life of a fuel cell quickly and cost-effectively, users can easily integrate the devices into an automated test system. The PSB 10000 series is also ideal as a test system for PV inverters, as it has the necessary simulation unit for solar cells.
