DC Electronic Load Meter 500KHz 600W 900W 1200W Battery withstand voltage capacity tester 150V Multiple measurement modes

English Manual

The Model1/2/3 is a precise program-controlled DC electronic load for power electronics testing. It uses a high-performance ARM processor and 500kHz high-speed sampling AD, with a 4.3-inch TFT color screen (Chinese/English optional), 0.0001 display resolution, USB HOST for data/firmware management, and full protection (over-voltage/current/power/heat, reverse polarity). Standard RS232C/HANDLER interfaces enable easy integration, compatible with mainstream serial protocols.
