Use of mains filters may be necessary for cases where the user must meet E.M.C requirements. The capacitor values given inside the filtering specification tables should be taken only as indications, the filter attenuation will depend on the final application. - Control input lines must be installed together to maintain products’ susceptibility to Radio Frequency interference. - Performance Criteria 1: No degradation of performance or loss of function is allowed when the product is operated as intended. - Performance Criteria 2: During the test, degradation of performance or partial loss of function is allowed. However, when the test is complete the product should return operating as intended by itself. - Performance Criteria 3: Temporary loss of function is allowed, provided the function can be restored by manual operation of the controls. **3** Specifications are subject to change without notice (03.09.2021) **RS1A** ## **Heatsink Dimensions (load current versus ambient temperature)** |**RS1A23..10, RS1A40..10**|**RS1A23..10, RS1A40..10**|**RS1A23..10, RS1A40..10**||**RS1A48..10, RS..25**|**RS1A48..10, RS..25**|**RS1A48..10, RS..25**|**RS1A48..10, RS..25**||||||| |---|---|---|---|---|---|---|---|---|---|---|---|---|---| |Load
