Veris,Current Switch,Split-Core,VFD,N.O., H904

• Hawkeye 904 microprocessor-based current status switches provide a unique solution for accurately monitoring status of motors controlled by variable frequency drives
• The H904 stores the sensed amperage values for normal operation at various frequency ranges in non-volatile memory
• This information allows the device to distinguish between a reduced amp draw due to normal changes in the frequency and an abnormal amp drop due to belt loss or other mechanical failures
• APPLICATIONS Monitoring positive status on motors controlled by variable frequency drivesReplacing pressure switchesMicroprocessor-based real labor saver No need to calibrate to detect belt loss on VFDsSelf-adjusting trip point factory programmed to detect belt loss undercurrent conditions
• Install and go Available with a relay;status and control in one package, saving time and space Bracket can be installed in three different configurations;added flexibilityAccurately detects belt loss and coupling shear on VFD driven motorsMonitors both frequency and amperage;distinguishes normal drops in amperage due to frequency changes from abnormal drops due to mechanical failureSplit-core design is ideal for retrofits; no need to remove conductor5-year limited warranty
