SVF-MN

MiniSensorless Vector Frequency Inverter

Voltage and power range

3phase, 380v: 0.4~5.5kw

3/1 phase, 220v: 0.4~3.7kw

Output frequency range: 0.00Hz-400.00 Hz





TechnicalAdvantage

Control mode

(1) VF control: Multipoint VF curve. This apply to the situation that one frequencyinverter drives multiple motors, such as fan, water pump, engraving machine,injection molding machine etc.

(2) Open-loop vector control: Steady speed with highprecision, wide range of speed governing, as the speed ratio is 1:150 and frequencyis 0.5Hz, we could output 150% rated torque. Good dynamic performance.

SVF-MN series frequencyinverter could be widely used in the industry of food, packing, textile,engraving machines, washing machine, offset machine and rolling door etc.


Q: What is the difference between the electronic governor and the frequency converter on the motor speed regulation?
Electronic governor is for single-phase motor, by changing the access winding resistance and capacitance to adjust the motor speed, the speed of the power supply power for the output does not change, so this speed is not an energy Type of speed control methods, such as home for the use of fans and the like. Inverter speed is the original direct input three-phase asynchronous motor power first access to the inverter, in the inverter through the PWM and other electronic converter technology to rectify the frequency AC, inverter, become a frequency controllable AC In the input to the motor, in the motor running through the V / F control, output torque control, vector control and other control methods to adjust the frequency, change the loop current, to achieve energy-saving operation, especially in the light load energy efficiency is obvious, An energy-saving products that have been widely promoted and applied
Q: What is the common COM point of the PLC and the inverter? Is it positive?
Plc is divided into two kinds of transistor output and relay output, com side may be connected to the high level may also be connected to the low level, the general input com port then low, the output port com mouth high, specifically what to take See the data sheet. Inverter is the same, the inverter has 24v com side and 10v com side, can not be connected together, com side generally low.
Q: Laptop power adapter is broken, which brand is better domestic
This is usually very compatible with the power adapter brand, you can only buy the original, or to the local computer market with a similar output power adapter can be,
Q: The relationship between the power supply of the notebook and the battery
2, when the laptop turns on the power adapter, and the battery power is low, the charging circuit detects the battery power is lower than the set value, the power adapter will side of the host power supply, while the battery charge. After the charge is restored, it is restored to the power supply state directly from the adapter. Therefore, the relationship between the power supply of the notebook and the battery is that the battery is charged by the power adapter when the battery level is below the set value.
Q: What is the laptop adapter
2, the basic composition: input line + charger main body + output line + connector such as Acharger single-band notebook charger composition, which constitute the basic elements of the notebook charger, as inside the internal parts is very complicated.
Q: Servo control system can give the inverter signal,
Servo motor driver can give the inverter signal, with analog output to control,
Q: Inverter problem
(0 ~ 20mA), but the main input / output is completely isolated, than the output of the inverter simulation of the output of the analog output The amount of signal impact resistance, anti-interference ability.
Q: Computer frequency changer to do cd frequency changer how points positive and negative
Two identical capacitors in series, the capacity is half of the original, the two capacitors in parallel after the same capacity doubled.
Q: Why the notebook power adapter can not be universal
Third, the current is different Different brands of laptop power adapter current is not the same, for example: under normal circumstances IBM is 4.5A, Dell is 3.34A, Hp is 2.7A, Sony is 4.1A and so on. In fact, the same brand of laptop power adapter voltage and current are not the same. So, even if the same brand of notebook computers channeling with power adapter to confirm the voltage and current specifications.
Q: Three motors, if coupled with the governor speed, is it necessary to add the inverter?
?Fourth, the electromagnetic speed: electromagnetic speed motor by the cage motor, electromagnetic slip clutch and DC excitation power. DC excitation power is small, usually by single-phase half-wave or full-wave thyristor rectifier composition, change the thyristor conduction angle, you can change the size of the excitation current.
