Kewell S7000 Series Bidirectional Programmable DC Power Supply

The Kewell S7000 Series devices are high precision bidirectional DC power sources with energy regenerative feature. As a DC source, they support dual quadrant energy flow. They offer high conversion efficiency and high-power density. The S7000 series 3U-size enables it to power up to 30 kW and output voltage up to 2000 V. For even higher output they support parallel operation of multiple devices. Operation is intuitive via a color touchscreen and front panel or remote-controlled via a variety of interface options. The S7000 series devices can be applied in battery testing, battery storage inverter testing, electronic testing of EV etc.
