S7000H Series Regenerative DC Source-Load Power System

 
.Bidirectional DC source
.Regenerative electronic load
.PV Array IV Simulation
  • S7000H

Summary


S7000H is a high precision DC power system supporting dual mode-source & load-with energy regenerative feature. 

(1) As a DC source, it supports dual quadrant energy flow; 

(2) As an electronic load, it supports energy recovery to the grid. High conversion efficiency and high-power density. 

3U-sized enables it to power up to 30kW and output voltage up to 2000V. Support parallel operation of multiple machines. Human-computer interface: Colorful touchscreen and knob. Can be applied in battery testing, battery storage inverter testing, electronic testing of EV etc.
