## Visão geral O Inversor de Frequência FR-A842-07700-1-60 da Mitsubishi Electric é um dispositivo de velocidade/frequência variável (VSD/VFD) da série FREQROL FR-A800. Ele conta com um conversor separado (FR-CC2), vendido à parte, revestimento protetor para a placa de circuito impresso e saída de pulso (PTO). Sua operação abrange uma faixa de tensão de entrada de 380V a 500V trifásicos, com capacidade para motores de até 315kW (420HP) em serviço normal (ND) e corrente nominal de 610A. Este equipamento suporta a comunicação Modbus RTU e possui um índice de proteção IP00. As tensões nominais de entrada suportadas incluem 400V, 415V e 480V. A resistência química do revestimento da placa de circuito impresso está em conformidade com as normas IEC60721-3-3 3S2 e 3C2. O código FR-A842-07700-1-60 é equivalente ao código FRA84207700160. ### Principais recursos
