Product Features:

1. Excellent dynamic response. Excellent torque and speed dynamic response, Sensorless vector control torque response time(time from 0 step to rated torque) is less than 20ms; Feedback vector control torque response time is less than 10ms; the dynamic response accuracy of the speed loop is 0.5%s.

2. Completely independent air duct structure. Electronic device and radiator duct isolation design, in which capacitance, MOS and relay to strengthen protection, machine a closed design is adopted on both sides of the device. Improve the tolerance of the machine in harsh environment.

3. EMC grounding design. Adopt innovative EMC grounding design, grounding canbe quickly selected through the terminal or intermittently.effectively solve EMC interference.

4. High starting torque. Low frequency high torque output. In feedback vector control mode, it can output 200% of rated torque at zero speed; in sensor-less vector control mode, it can output 150% of rated torque stably at 0.25Hz.

5. Super strong overcurrent suppression ability. The overcurrent suppression function can avoid the overcurrent fault caused by sudden load or interference in frequency converter. Reduce the loss caused by unexplained shutdown.

6. Super strong overvoltage suppression capability. The overvoltage suppression function can avoid the overvoltage fault caused by the bus voltage rise of the variable frequency drives.

7. Fast disassembly and assembly design of the fan. ZK300 adopts innovative fan structure design. On the premise of ensuring the stability and efficiency of the fan, it can be replaced and cleaned quickly without the help of external tools.

8. Overexcitation braking function. In the case of partial inertia shutdown, the braking resistor can be used without increasing the braking resistance, and the over-excitation braking function can be used realize fast braking and improve product ease of use.

9. Excellent speed tracking performance. In a very short time to achieve speed tracking start with identification direction, greatly reduce the impact of shutdown and restart.

10. Protective function. It has output short-circuit to ground protection, internal buffer relay protection, fan drive circuit protection, external 24VDC short circuit protection, motor overload protection and other hardware protection which can comprehensively protect the internal and peripheral equipment of the drive.
