1. Introduction of SY7000 Frequency inverter

SY-7000G high torque 380V three-phase Frequency inverter (VFD), frequency converter, ac inverter, variable speed drive, frequency inverter, ac drives---Digital control machine tool-purposed type.

2. Features of SY7000 Frequency inverter (VFD) frequency inverter.

Various control modes and widely used.

0.3 Microseconds instant protection

Sanyu inverter is using independent intellectual property rights of software algorithm and circuit design, through the use of an advanced electric current sampling mechanism, using the hall switch to strengthen the protection of the inverter itself and peripheral equipment, to strengthen its security. The sampling parts are the international well-known Japanese Tamura Hall, LEM Hall, 0.3 microseconds response time can inhibit the effect of electromagnetic interference, can absorb a certain amount of vibration, can adapt to poor working conditions.

Automatically recognize the motor parameters of VFD.
