Solid State Relays Low Electromagnetic Noise Emission Types RA 24.. -D 06 L, RA 40.. -D 08 L * * * * * * AC Solid State Relay Zero switching For ohmic load applications Rated operational current: 10 and 25 AACrms Rated operational voltage: Up to 400 VACrms 10 A type meets CISPR 22 B requirements Product Description Ordering Key This relay is designed for use in applications where low electromagnetic emission is essential. Solid State Relay Switching mode Rated operational voltage Rated operational current Control voltage Non-rep. peak voltage Low RFI Today, household and electrical appliances, information technology- and medical equipment must conform with the latest EN standards. These new EN standards define general and product related requirements for noise immunity and noise emission. The RA24..-D06L and RA40..D08L are relays for applica- tions where the noise emission must be low and where the customer does not want to relinquish all Solid State Relay features. The relay is available with zero crossing function. It is designed for resistive loads, i.e. power factor = 1. RA 24 25 -D 06 L Predestined applications for this relay are office machines, ovens and cookers for domestic and industrial use, theatre or stage lighting systems, film processing and copying machines or medical equipment.

Therefore the relay must have the synchronization input connected to the mains, either to neutral or to the phase depending on how the load is connected. The relay can only switch resistive loads with a power factor of 1. A minimal load current of 1A for the RA ..10 -D 0. L and 2 A for the RA ..25 -D 0. L is required as long as the control input is activated. Compare the value found in the current versus temperature chart with the standard heatsink values and select the heatsink with the next lower value.
