EM330D Builder lift inverter

3-phase 380 V-20%~415V+20%, 3.0~400kW

EM330D is a specially designed inverter for hoisting in open loop control mode like builder lift etc.

1.Technical Features

① . Stable torque output, 150% rated torque at 0Hz, the hoist operates smoothly during starting, hoisting and fall.

② . Special brake control logic.

③. Optimum current limit, trip fault will not occur when the load varies frequently.

④. Wide range of input voltage by AVR technology, high torque output remains when under voltage.

⑤. Wide range of speed regulation meets the requirements for high speed under light load and low speed under heavy load, significantly increasing the operation efficiency of the hoist.
