The sensorless standstill monitor UG 9146 is used for sensorless monitoring of electric motors for standstill. It measures the induced voltage of the coasting motor at 2 terminals of the stator winding. If the induced voltage approaches 0, this means motor standstill for the device and the output relay switches on.

Features

According to EN 60 255-1
Standstill detection on 3- and single-phase motors
Independent of direction
Broken wire detection
Forcibly guided safety contacts:- 2 NO contacts for AC 250 V- 1 NC contact for DC 24 V
Adjustable voltage setting
Adjustable standstill time delay
LED indicators for standstill, event of line breakage and operation voltage
Suitable for operation with inverters
Removable terminal strips:- UG 9146 PS: plug in screw terminals- UG 9146 PC: plug in cage clamp terminals
Width: 22.5 mm
