Earth-fault detector - max. 500 V, 50 - 150 kΩ | ISOLTEST series
The Isoltest Medical Series is ideally designed to provide an excellent quality performance for very specific purposes. It is mainly constructed for operating theaters specifically for a continuous monitoring of the insulation tolerance to the earth. The unit is connected to the single-phase and three-phase networks with up to 500 voltage capacity incorporated with a neutral insulated system from the earth's downstream. Once the insulation resistance falls down on the specified value, the unit then starts to operate activating an acoustic signal. The calibration is handled by a potentiometer which located at the front part of the device which enables a control between 50 kohm and 150 kohm.
