Frequency inverters CHZIRI

Detailed description of the goods

Frequency inverters series  ZVF11 and  ZVF9V-G-M is designed for conversion of single-or three-phase voltage with constant frequency 50 Hz three-phase voltage variable frequency range from 0 to 400 Hz (PWM) frequency inverters this property makes it possible to use them for any variable speed asynchronous motors, including electric compressors, elevators, hoists and other mechanisms for user's conveniencenon-industrial-phase network we offer frequency inverters series ZVF11-M for single-phase (two cable) power 220-240V AC, up to 2.2 kW, and frequency inverters series ZVF9V-G for three-phase 380V.   

• Range — 20%/+ 20% of the rated voltage and frequency deviation ± 5%, is the standard for electric vehicles, which is necessary for sustained work in Russian networks. Frequency inverters series ZVF9V-G and ZVF11-M   fully meet these requirements:
• existence of PID control (proportional to Integrally Differential regulator) provides industrial algorithm used for the maintenance of controlled values (pressure, speed, flow, temperature) within the specified bounds using
sensor.
• frequency inverters series ZVF11-M and ZVF9V-G has good overload capacity 150% for 1 min., 200% for 1 sec.
• there are four variants of time acceleration and braking of the motor from 0.1 to 999.9 seconds
• existence of vector control maintains a high torque at low speeds of rotation, or stable speed when racing loads.
• Six multi-function terminals allow to 24 kinds of settings.
• for the implementation phase the engine braking in DC is to create a braking torque, and the shaft is fixed at a given position.
• RS485 port availability to use the ModBus communication protocol
