Overview
Explosion-proof and intrinsically safe inverter for mining use, covering two voltage levels of 660V and 1140V,
with a power range of 75kW~400kW.
The products cover two voltage levels of 660V and 1140V, power range of 75kW~400kW, with various control
modes such as IFD control, VTC [non-inductive vector control],
FOC [field oriented vector control], SYN [permanent magnet synchronous], etc., and support RGN
[energy regeneration control],
SYN [permanent magnet synchronization] and other control modes, supports RGN [energy regeneration
control], low-speed starting torque up to 240% of rated torque.
It supports RGN [energy regeneration control], and the low-speed starting torque is up to 240% of the rated
torque, which can satisfy the needs of loaded starting, stepless speed regulation, energy-saving operation
and so on.
