Electrical terms in electricity sector is vital to do a professional job. Today we will review the electrical terms. Here the details of subject.
Operating voltage Ub
The operating voltage Ub indicates the voltage range in which the proximity switch complies with its guaranteed operating data.
Nominal voltage Un
The rated voltage Un is the voltage specified by the real switching distance Sr at 293 K (20 ° C). It is 24 V DC for DC switches and 220 V AC for AC switches.
The minimum load is the smallest load required on two-wire AC switches to ensure safe operation of the proximity switch.
