ISOMETER® isoRW425

ISOMETER® isoRW425

El ISOMETER® isoRW425 vigila la resistencia de aislamiento (ModoR) o la impedancia de aislamiento (Modo Z) de circuitos de corriente principales AC/DC aislados de tierra (sistemas IT) con tensiones de red de 3(N)AC, AC, AC/DC o DC 0…440 V. Los componentes alimentados con corriente continua en sistemas 3(N)AC y AC/DC no influyen sobre el comportamiento de respuesta, si fluye por lo menos una corriente de carga de DC 10 mA. Una fuente de alimentación externa permite realizar la vigilancia del sistema en sistemas sin tensión. La capacidad de derivación de red máxima Ce en Modo R es de 300 μF y en Modo Z de 1μF.
