Características de KE300A-11 Series High Power and High Protection Inverter

  • Fácil de instalar e depurar

  • Concepção EMC sólida, forma única de radiador.

  • Adopção modular design

  • O principal sistema de controlo utiliza o DSP de Alta Velocidade 32-bit, controlo integrado do vetor SEM PG, controlo V/f e controlo do binário.

  • O modelo optimizado de identificação do parâmetro motor Pode efetivamente reduzir a sensibilidade AOS parâmetros do motor e tornar a auto-aprendizagem Mais precisa.

  • Torque de arranque elevado: 150% do binário de arranque Pode ser fornecido quando está EM 0.5Hz;

  • Resposta dinâmica rápida: De acordo com o modo de controlo vetorial SEM PG, o tempo de resposta dinâmico é inferior a 20ms;

  • Built-in PID regulador Pode facilmente formar um sistema de controlo EM circuito fechado para quantidades de processo, tais Como temperatura,Pressão e fluxo.

  • Tem funções de reposição automática de falhas e de reposição de Energia para garantir a produção contínua e a eficiência Da produção.

  • Funções de protecção perfeita: protecção contra a sobretensão/subtensão, protecção do sobreaquecimento do inversor, protecção contra a falha no solo, protecção de curto-circuito, protecção excessiva, protecção por sobrecarga, etc.
