BPJ series mine explosion-proof and intrinsically safe AC frequency conversion speed regulation device (hereinafter referred to as inverter) is suitable for starting, stopping and speed regulation of motors in dangerous environments containing gas (methane) and dust explosions. It has the advantages of large starting torque, stable starting, adjustable starting acceleration time, small starting current, small impact on the grid, and obvious energy saving in operation. With the continuous progress of industrial automation, energy-saving requirements continue to increase, especially in the fields of belt conveyors, winches, fans, water pumps, etc., frequency inverters have also been widely used.

Features:

● Adopt advanced direct torque control (DTC)

Large output torque, 150% rated torque can be reached at 0.5Hz

Maximum output torque can reach 200%

● Allow a wide range of rated voltage fluctuations

-15%～+10%, used in power supply system underground in coal mine

● Have a perfect braking method

DC braking, dynamic braking, feedback braking (optional)

● Advanced heat dissipation method
