Product Description
Frequency Inverter 220V/380V 50-60Hz Single/Three Phase Frequency System For Food processing MachineB300 frequency inverter features:
A. Excellent open-loop vector control performance, eliminating the need for PG (speed sensor), saving costs and increasing system reliability:B,Excellent dynamic response capability: advanced motor model control is adopted, and open-loop vector control can also respond to sudden changes in load quickly;
C, wide range of weak magnetic control: under certain conditions, the frequency adjustment range can be increased to meet the short time overload operation requirements;
D. High efficiency MTPA algorithm: The unique low-loss modulation algorithm can reduce the loss of the inverter by 30%, combined with the The energy-saving operation curve of the motor can greatly improve the energy-saving rate of the system;
E. Multi-modal protection and inverter protection: motor protection includes motor overheat protection, motor overload protection, motor phase loss protection, speed limit protection, and motor overload protection.
Motor protection includes motor overheating protection, motor overload protection, motor phase failure protection, speed limit protection and torque limit protection; inverter protection includes output current limit, inverter protection, heat sink overheating protection, power supply failure, IGBT overheating protection, loss of analogue input signal (speed The protection of the inverter includes output current limit, inverter overload protection, heat sink thermal protection, power supply failure, IGBT overheating protection, analog input signal loss (speed loss), communication abnormality protection etc.
F. Good adaptability to the environment: PCB thickened coating treatment, can be customized with special thermal design, reduce the size of the inverter:
G. Modular platform of inverter hardware, control layer, power layer and display interaction layer in a layered design;
H. Built-in RS485 communication interface, support MODBUS-RTU communication protocol:
1,Independent air duct design, effectively prevent dust from entering, fan can be freely removed, good heat dissipation and high reliability.
J,Using high performance closed loop vector control, it can meet most of the closed loop control applications. PG card, PG card with differential encoder and rotary change.
