Function:

● Short-circuit protection: long-term short-circuit or short-circuit startup is allowed under different working conditions;

● Constant voltage and constant current: The voltage and current values are continuously adjustable from zero to the rated value, and the constant voltage and constant current are automatically converted;

● Intelligent: Optional analog control and PLC connection to form a remotely controlled intelligent stabilized current power supply;

● Strong adaptability: suitable for various loads, the performance is equally excellent under resistive load, capacitive load and inductive load;

● Overvoltage protection: The voltage protection value is continuously adjustable from 0 to 120% of the rated value, and the output voltage exceeds the voltage protection value for trip protection;

● Each power supply has enough power surplus space to ensure that the power supply can ensure good performance and longevity when it works at full power for a long time.
