How Does A Magnetic Separator Work?
EM500 series Universal frequency inverter.
Open loop vector control inverter EM500 series: support He Yongci AC three-phase asynchronous motor synchronous motor drive control; to support a variety of international leading technology: VF vector control technology improvement (VVF), the speed sensorless vector control technology (SVC); support two forms of output speed and torque; support: I/O extension card, communication bus expansion card. EM500 series frequency converter is suitable for speed regulation of industrial machinery with speed open loop control and energy saving of fan and pump
Specification
Feature
● High precision of torque control: SVC/±5% Rated torque
● The speed range is wide and the control precision is high: VVF/1:50; SVC/1:200, stability speed, ±3rpm/0.2%
● Low frequency load: VVF/1Hz/150%、SVC/0.25Hz/150%
● The output of the three phase current sampling, the output to the ground short circuit can also be fully protected, as well as overvoltage and stall, fast current limiting, overload, overheating, load off and so on.
● Supporting the extension of the mainstream field bus and supporting I/O extensions
● 11kW begins with a built-in DC reactor to enhance the adaptability of the power grid
● Wave by wave current limiting capability to reduce the number of times of skip flow protection
● 1 way high frequency pulse input, output, 2 circuit relay output
● The volume of partial power is obviously reduced to meet the requirements of miniaturization
● Support asynchronous motor and synchronous motor at the same time
● The maximum power is up to 630kW
