380V Frequency Converter Small Size Mini VFD 0.75KW VSD For Welding
Machine
Products description of variable frequency drive
1. With TI's latest high-speed DSP chip and independent
intellectual property control software,
the motor can run stably in various application environments by
giving full play to the characteristics
of software and hardware.
2. New wave by wave current limiting control algorithm, stable
current, and voltage control, ensure the
inverter to run without fault under limit conditions
3. New current, voltage, control algorithm, plus a unique
excitation current control, to ensure that the motor
fault free fast start and stop.
4. New motor model, low-frequency motor running speed stability,
high torque, current control accuracy, no-fault shutdown,
high-frequency motor running speed stability, low current.
5. New software speed tracking algorithm, tracking current, voltage
impact is small, tracking speed is accurate
6. The carrier frequency can be automatically adjusted with the
frequency conversion temperature and operation
frequency to ensure reliable operation under the condition of a
small frequency conversion temperature rise.
7. The maximum frequency of a standard machine is 3000hz, one
machine is multi-purpose, which can meet the
multi-purpose processing needs. It can realize a variety of
frequency switching.
8. Super overload capacity, 150% 60s, 180% 10s, 200% 0.5s
9. Default one set of motor parameters, can customize multiple sets
of motor parameters, can drive different types of motor.
10. Four times of fault parameter record, detailed record of the
detailed state of the inverter when the fault occurs, and
record the maximum current, maximum voltage and maximum temperature
during the operation of the inverter, so as
to facilitate the analysis and treatment after the fault occurs
Quality assurance of variable frequency drive
1. All products have passed CE, ROHS, ISO9001, FCC Certifications
2. Every production link of the product is tested by professional
personnel
3. Professional product engineer is responsible for after-sales
service
