Variabel frequency drive

ET1000 SERIES General-purpose frequency inverter 220V( single phase power) 0.4-2.2 kw 220V(three phase power)0.4-75kw 380V(three phase power)0.75-1000kw . V/F control mode brings the same feeling as vector inverter control 1, Low output harmonic prolongs lifetime of motor. 2, Auto-adjust carrier frequency according to module temperature to adapt the environment. 3, Super low carrier frequency technology effectively reduces inverter output current leak. 4, Flexible multi-steps V/F control mode. 5, Perfect auto-improve torque function. Auto- supply super startup torque function. The most strong environment adaptability. 1. Wide voltage range and voltage modulation technique ensure the carry capacity. Functions as anti-surge (thunder induction), anti-noise and static resistance have reached strict industrial standard. 2. All standard products are processed with three “proof” lacquer to stand in occasions with high humidity and where the rate of dust exceed standard. More strict treatment will be adopted for more strong protection function to work in worse environment. 3. All series products adopt independent cooling channel designing. Middle or high power inverters adopt hermetic style designing to work in worse environment. Instant break protection and no stop function It will use motor reborn energy while meeting instant power break. The inverter will continue to work while power on again. (Take air condition energy saver or fan as example as below) Perfect functions; wide using range Wobble: Used in occasions where needs wobble control mode, such as textile, fabric. According to the parameters, freely set the range, speed, frequency. Wobble output frequency Strong communication function Master-slave communication is based on international standard ModBus communication protocol. Centralized control is carried out via PC/PLC, upper machine and master inverter (By set control order, running frequency, corresponding parameters modification, monitoring of the running state and malfunction information) to satisfy the specific requirement. Simple PLC. Up to 15 steps speed control Above 160kw standard DC reactor adaptor Above 160kw standards DC reactor brings super low input harmonic and supper high input power factor to protect the power grid very carefully. Universal DC master line technology More energy saved; Better environment protect function; More economical. Rich of terminal function Outside terminalVS1: 0-10v, outside terminal VS2:-10V—10V. Outside terminal AS:4—20Ma, RS485, frequency pulse input; Other functions includes startup, stop, positive turn and reverse, jog, multi-steps speed, free stop, reset, choice of acceleration time and deceleration time, frequency setting channel choice, alarm for outside malfunction; relay output, collector output, 1-10v output, 4-20mA output, frequency pulse output and so. Quick and stable PID control function Multi PID control modes: common PID and PID special for press closed-loop. Wider using range and more customized. Carton packing with foam inside.
