Chart of SP sensors (dis)connecting

Example of magnetic toroid:

Parameters of protecting parts: D=69 mm, d=46 mm, h=8 mm, mat.: D300
Hm=9600 Acm-1, Hc=2200 Acm-1, axial magneting

Parameters of contacts of SP-x sensors are defined for ohmical load reading. It has to be diode, RC circuit, overvoltage protection (varistor, transil) or its combination used for correct function of SP sensors. More info see below.

Protecting while DC connecting

Parameters of safety components: Diode has to be dimensed for current in the electric circuit and the closing voltage of diode has to be 2 fold against connecting voltage. Varistor has to be dimensed at 1,5 fold of connected DC voltage.

Protecting while AC connecting

Parameters of protecting parts: Capacity of capacitor should be 0,05 – 0,5 microF, capacitor of type MP for min. voltage 3xUef. connected.
-Resistance 56 ohm (47-100). Varistor has to be dimensed at 2,5 fold of ef. value of connecting voltage.
