Repeatedly short-term rated operation mode (S3)

In this case short-term mode with constant rated load is alternated with pauses in EM operation. It should be mentioned, that heating temperature doesn`t reach steady temperature at every operation time, and EM doesn`t cool down to the environment temperature at any pause time.

Repeatedly short-term rated operation mode is characterized by ratio of engaging duration.

,

де ED- engaging duration;

- cycle time;

- operation time;

- pause time.

Value of ED is stated:

ED =15; 25; 40; 60 (%), or

0,15; 0,25; 0,40 and 0,60.

For the S3 mode rated data correspond only appropriate value of ED and refer to the operation time. It is also stated the limits of allowable cycle duration.

.

S1-S3 modes are basic for now. Rated data of EM for these modes are fulfilled in the ratings and catalogues.

S1-S3 modes are using inside the following devices:
