Megger PSI410 PSI410, rotating field display

For machines and devices with three-phase voltage supply, determining the correct rotation field for specific motors and pumps is very important. Incorrect rotation fields can cause damage during startup. The rotation field indicator PSI410 displays the rotation field in networks up to 500 V. The rotation field is indicated by two-color LEDs and an acoustic signal. A clockwise rotation field is indicated by green LEDs rotating clockwise, along with a continuous tone. A counterclockwise rotation field is indicated by red LEDs rotating counterclockwise, accompanied by an intermittent tone. The correct connection of the three external conductors is indicated by additional two-color LEDs. A green LED indicates that the external conductor is present, while a red LED indicates an incorrect or missing connection. The robust housing has an IP65 protection rating, and the device is designed for measurement category CAT IV / 600 V. Test probes with crocodile clips are included as accessories. The PSI410 rotation field indicator does not require batteries, as the device is powered by the measurement voltage. The connection wires are color-coded (brown/black/gray) for clear identification.
