PLCAGE: CHF100A-045G/055P-4 Invt CHF100 Series high performance universal inverter 3 Phase 380V-440V 45KW/55KW New

Introduction

CHF100A series high performance universal inverter is the enhanced edition of CHF series, which is combined the advantage of CHF100 & CHE100. It adopts the DSP control system supplies sensorless vector control and V/f control. The performance is more perfect and stable. It is widely applied in Pump & Fan and some applications with high speed control accuracy, rapid torque response and high performance at low frequency.

Features

*Three control modes: without PG vector (SVC), V/F control, and torque control;

*Starting torque: without PG vector control: 0.5Hz/150% (SVC);

*18.5kW-90kW inverter built-in DC reactor to improve input power factor and increaseoverall efficiency and stability;

*Internal brake unit with every specification 0.75-15kW, so that the braking resister can be connected directlyfor a quick stop;

*16-steps simple PLC, multi-speed control, and PID control

*Supporting multi-frequency installation methods: digital setup, analog quantity setup, PID setup, and communication setup;

*Supports starting and stopping DC brake;

*The input and output terminals may be freely programmed, so users may combine a variety of operating modes as needed;

*Equipped with jump frequency control which prevents mechanical resonance and makes the system more stable and reliable;

*Equipped with instantaneous power failure non-outage capability;
