Overview

Kewell Programmable Bidirectional DC Power Supply, S7000H Programmable Bidirectional DC Power Supply is a high-precision programmable bidirectional DC power supply with feedback function, which can be used as a DC source to support energy flow in two quadrants and as an electronic load to support energy feedback to the grid. This model has the characteristics of high conversion efficiency and high power density. The 3U size can support a power of 30KW and an output voltage of up to 2000V. In addition, the model also supports multi machine parallel connection function. The human-machine interface supports both color touch screen and button knob operation modes, meeting customers' different usage habits. Can be applied to testing new energy batteries and energy storage inverters.
