improve the protection capability of the system. It is applicable to the applications
with dusty and corrosive environment, such as wire-drawing machine, printing and
dyeing and ceramics.
Wide voltage range design: the DC operating voltage range is DC 360
−720V, with
mains voltage fluctuation recording function.
Precise current detection and protection: The full series adopts precise Hall sensor
to detect the output current, meeting the quick real time control and protection
requirement of software and hardware, ensuring the performance and reliability of
the system.
Independent power supply for control: The system provides independent switching
power DC input port. External UPS power supply can be realized through option
card. It is applicable to the applications of oilfield, chemical industry and printing and
dyeing industry.
Power-up self-detection function: It realizes the power-up detection on the peripheral
circuit, such as motor grounding, disconnection, greatly improving the reliability of
the system.
Comprehensive system protection function: software/hardware current limiting
protection, overcurrent and overvoltage protection, grounding short circuit protection,
overload protection, IGBT short circuit protection, abnormal current detection
protection, abnormal relay contact protection.
Perfect terminal protection function: short circuit and overload protection for the
+24V and +10V power supply of the control terminal, operation panel cable reverse
connection protection, input signal cable disconnection and abnormal analog input
protection.
Over-temperature prealarm protection function: Automatic adjustment will be made
according to the temperature to ensure the reliable operation of the product, and
maximum operating temperature will be recorded.
Comprehensive switching power protection function: including switching power
output short circuit protection, overload protection, power-up walk-in function, open
loop self-locking and voltage limiting protection function, ensuring the reliability of the
system.
