Split Core Adjustable Set-Point Digital Output VFD Current Switch, 3.5-135A, 20-75Hz Amp Range, Normally Open With Status LED 0.1A@30VAC/DCThe Hawkeye 904 microprocessor based current status switch provides a unique solution for monitoring status of motors controlled by variable frequency drives. Provide accurate status on loads controlled by variable frequency drives. The H904 stores the sensed amperage values for normal operation at various requency ranges in non-volatile memory. This information allows it to distinguish between a reduced amp draw due to normal changes in the frequency and abnormal amperage drop due to belt loss or other mechanical failures.
