Kewell D2000-IV: DC Power for Battery and Converter Testing
How do batteries, DC/DC converters, and power converters behave under changing voltage and load conditions? The Kewell D2000-IV Series provides programmable DC voltage and current and can feed energy back into the utility grid during bidirectional operation. This enables reproducible simulation of operating conditions and testing of device responses. Depending on the model, output ratings of up to 2,000 V and 600 kW are available. Parallel operation allows the total power to be increased.
Beyond conventional DC power supply operation, the D2000-IV simulates the behavior of different battery types using predefined battery chemistries or custom battery models with adjustable state of charge.
For PV inverter testing, it operates as a PV Simulator: Changes in irradiance or temperature affect the simulated I-V curves, allowing targeted testing of maximum power point tracking (MPPT), including under simulated shading conditions. SiC power semiconductors and an interleaved buck topology support fast dynamic DC regulation, with efficiency reaching up to 95.5%.
The modular design simplifies maintenance by allowing individual modules to be replaced. The Normal, Pro, and Ultra versions differ in accuracy and dynamic performance; only Pro and Ultra feature a dedicated electronic DC load function.
Alternative Products
If your application requires higher output currents, the Kewell D2000-EV Series is an alternative, offering up to 1,200 A. For DC testing applications with lower power requirements of up to 30 kW, the Kewell S7000-H Series is a suitable option.
