Components Brand:
ABB inverter is a famous brand which researched & produced from ABB group. That used in control & regulate three-phase AC asynchronous motor. It has played important role in the marketing for its stable performance, rich combination , good vector control technology,Low-speed, high torque output, dynamic characteristic and super overload capacity.
Operation principle:
Rectified and filtered AC 380V to DC510V with inverter, and change DC510 to AC with voltage and frequency adjustable use converter. Voltage: 0~380V, frequency: 0~600HZ. So that can control motor speed stepless.
Products Features:
1、According customer requirements, ABB inverter is the core of our products. The design & manufacture has distinctive characteristics.
2、Each procedure for control box is strictly controlled, such as purchase, producing, inspection, shipping. Every step conform to 3C certificate.
Before production, we will prepare Electrical principle diagram and choose the suitable components brand for assembly according customer’s requirements, such as working conditional (temperature, humidity, radiation, proof degree of explosion), motor parameter (original, rated current, rated voltage, phases, loadtype, starting system), control method (manual function or automatic function), local control or remote control.
We also prepared some precaution for some potentially interference, such as, reactor, isolation transformer, shielded cable, install lighting protection.
Finished electrical principle diagram, we must consider cabinet design, cabinet material, protection degree, fix cooling fan, electric wiring, components installtion, ambient temperature, ambient humidity.
Other components:
For our control cabinet, cooperated with many good reputation and best quality supplier. Contractor produced from Schneider & CHINT, breaker from Schneider, CHINT, MITSUBISHI, indicator light from Schneider & CHINT, intermediate relay from Schneider & CHINT & Omron, PLC from Siemens. Our quality is garanteed because of good design and reliable components.
Applications:
Products widely used in cooling fan load, pump load with PLC technology, PID algorithm, frequency.
