Ming Flameproof and Intrinsic Safety AC Frequency Converter

Function:

This product is mainly used in underground coal mines, where there are mixed explosive gases, such as methane. It is used to control, protect and measure the power system, which is rated voltage ***0V or **0V, and rated power between *5kW and **0kW. By changing the frequency and voltage, it can control the speed of belt conveyors and other machines, and so it can do necessary adjustment and protection to the motors.

It can be used

To control the Emulsion Pump (energy saved *0%**0%)

To control multiple motors synchronously

To control the main steel dragged belt conveyor and the assistant conveyor in inclined coal mines

To control the main motors of all power and save energy

To control the air compressor and save energy

To control high-power scraper conveyor and save energy

Also, it can be used to control the soft start, soft stop and operation process in open coal mines, port terminals, coal separating plants, and power plants with harsh environment.

Features:

It starts with a stable and small current with a large torque, which diminish the damage to the power system.
Liner and curved starting modes can be adjusted according to on-site situation so as to diminish the damage to machines while starting up.
On line control adjusts the working voltage and frequency according to load changes so as to reach required torque.
Energy can be saved, cutting down *0%**0% electricity.
Synchronous control of single or multiple motors in series with constant power and voltage, can meet all kinds of demands, especially the control of high power crane.
Precise high-speed, mid-speed and low-speed adjustment, helps to hold constant torque, constant power and V/F.
RS**5 interface is compatible with remote communication control.
It can be used to balance multi-motors.
Emergency frequency bypass system is available for convenient frequency conversion while production.
Anti-condensation preheating system can prevent condensation and short-circuit by preheating before starting.
The operation panel offers excellent human-machine conversation, displaying running parameters and fault information.
All parameters can be modified externally, which is easier and safer.
Advanced sensorless vector control is adopted. When starting with a low frequency, it will be double torque output and function well when overloaded.
Low frequency rotation: Auto torque compensation and low speed full torque when overloaded
