Veris H904 Current Switch

Features

  • Automatically compensates for the effects of frequency and amperage changes in monitored conductor associated with VFDs
  • Nuisance reduction – provides a secondary setpoint option of 50% of the originally measured current
  • Rapid troubleshooting – LED indicates normal and alarm conditions
  • Induced from monitored conductor sensor power
  • LED status, LED relay power

Veris Industries is an energy and environmental sensor partner that provides quality products for commercial HVAC and other automation applications. We offer complete lines of reliable, long-lasting innovative power monitoring products.

Hawkeye 904 current monitoring devices provide unique solutions for accurately monitoring the status of motors controlled by variable frequency drives. The microprocessor-based H904 store 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.
