Feedback DC Electronic Load Ainuo ANEL800-900C(F)

Description

ANEL（F） series feedback DC electronic load adopts high-frequency PWM rectification and bidirectional DCDC conversion, FPGA digital control, energy feedback to the grid at full power, more energy-saving, green and environmentally friendly compared with conventional DC load; advanced digital control, ultra-high control accuracy, fast response, wide output voltage range, it can achieve full range of load input from 0V to full scale.

The feedback DC electronic load realizes the DC load function of automatic energy feedback to the grid. Compared with the conventional load, it is more convenient and safe. The conventional load is energy-consuming, and energy is consumed by resistance heating; the feedback DC electronic load is energy-feeding, and the energy is fed back to the grid, green, environment friendly, reliable, safe, featuring outstanding advantages.
