▇ The power supply features overcurrent protection, shutting off the output within half a cycle when the output exceeds twice the rated current;
▇ Output is shut off when the temperature of the controller heat sink or main transformer exceeds the set threshold;
▇ The power supply supports MODBUS and PROFIBUS module expansion for convenient factory-wide control;
▇ It offers multi-unit power supply parallel operation with power distribution capability, effectively reducing system impact on the grid, improving distribution transformer utilization, and lowering overall system investment;
▇ The power supply provides an excellent human-machine interface for easy on-site operation;
▇ The factory can customize equipment dimensions according to specific site space requirements, offering either integrated or split configurations.
