Application
When designing switching loads, the usual discount factors for SSR relays from the specified nominal load must be taken into account. So are e.g. B. for switching inductive loads (e.g. motors) when using SSR relays, often only 1/8 of the specified nominal load of the SSR has to be taken into account for operation with motors. For ohmic loads, the actual load can usually be up to 80% of the specified nominal load. With medium to high loads and ED >20% (ED = duty cycle), the use of a heat sink to dissipate thermal energy is necessary. As a preventive measure, we generally recommend the use of suitable heat sinks.
