1: High-speed MCU is the main control chip
?2: Adopt RS485 international standard communication protocol
?3: constant current (CC) constant voltage (CV) double load mode
?4: Set the load value independently for each channel
?5: DC power supply isolation
?6: Optically isolated communication
?7: Multi-channel parallel use
?8: Automatic over-temperature protection
?9: Quickly set the read parameters
?10: High reliability MTBF 80000 hours or more
