CHE100 Series Sensorless Vector Control Inverter

CA800

Main technical features:
1) Output frequency range: 0.00 ~ 600.00Hz
2) Speed control mode: sensor-less vector control (SVC), V/F control
3) Command channel mode: operator panel, terminal and remote 
    communication
4) Frequency setting mode: digital keypad, analog input (current / voltage 
    signals), remote communications, multi-step speed, PID closed loop 
5) Starting torque: 150% / 0.5Hz (SVC)
6) Carrier frequency range: 1.0K ~ 16.0kHz
7) Speed control accuracy: ±0.5% max. speed (SVC)
8) Automatic voltage regulation (AVR): if the voltage of the power grid 
    changes, the system can automatically maintain a constant output 
    voltage 
9) Torque limitation: the max. torque can be limited to protect the inverter 
    reliably
10) Common DC bus: multiple inverters share the same DC bus and can 
    implement automatic energy balance
11) Wobble frequency control: multiple triangular wave curves, meeting 
    the personalized requirements of the textile industry
12) Multi-functional Quick / Jog key: can serve as a multi-functional key to 
    meet the requirements of users for multiple applications 
13) All input and output terminals are programable, for the convenience 
    of users

Reliable design:
1) Full series independent duct design: the heat sink supports installation 
    inside or outside a cabinet (optional). The fans are convenient to replace 
    and the inverter is simple to maintain, which greatly improves the 
    reliability of the inverter during long-term operation in such different 
    application environment as textile, printing and dyeing, chemical fiber, 
    paper making, wire-drawing, and cement manufacturing
2) Wide power grid voltage design: when the input voltage of the power 
    grid ranges from -15% to 15%, the inverter can run safely, and users 
    does not need other handling 
3) CHE series inverters above 7.5kW are configured with built-in DC 
    reactors which improve output power factor and the efficiency and 
    thermal stability of the integrated equipment, effectively eliminate the 
    influence of the higher-order harmonic on the input side upon the inverter 
    and reduce external interferences
4) Self safety test: upon power-on of the inverter, the system will conduct
    complete safety self-test of the software and hardware. The system 
    implements safe clamping of the modification and setting of functional 
    parameters, to prevent error settings of the functional parameters
5) Powerful protection: 
    a) Provides users with more than 30 kinds of fault protection functions, 
        and capable of all-around protection of inverters, motors and peripherals
    b) Provides the function of automatic reset upon a fault, to facilitate 
        automatic removal of conventional faults
    c) With built-in lightening over-current protection unit, to efficiently improve
        protection from lightening induction
