1 Solid State Relays Industrial, 1-Phase ZS, Standard Range Types RA /RA /RA AC Solid State Relay Zero switching Direct copper bonding technology Rated operational current:, 2, 0 and 90 AACrms Blocking voltage: Up to 10 V p Rated operational voltage: Up to 480 VACrms 3 input ranges: 3 to 32 VDC, to 90 VAC/DC and 90 to 280 VAC/DC Isolation: OPTO (input-output) 4000 VACrms Product Description The zero switching relay with antiparallel thyristor output is the most widely used industrial SSR due to its multiple application possibilities. The relay can be used for resis- tive, inductive and capacitive loads. The zero switching relay switches ON when the sine curve just crosses zero and switches OFF when the current crosses zero.

5 Applications This relay is designed for use in applications in which it is exposed to high surge conditions. Care must be taken to ensure proper heatsinking when the relay is to be used at high sustained currents. Adequate electrical connection between relay terminals and cable must be ensured. Heat flow Thermal characteristics The thermal design of Solid State Relays is very important. It is essential that the user makes sure that cooling is adequate and that the maximum junction of the relay is not exceeded. If the heatsink is placed in a small closed room, control panel or the like, the power dissipation can cause the ambient to rise. The heatsink is to be calculated on the basis of the ambient and the increase in. Direct bonding In the design of the output power semiconductor direct bonding of the copper layer and the ceramic substrate has been applied. This is to ensure uninhibited heat transfer and high thermal fatigue strength. The relay has been designed for applications requiring large numbers of load cycles. dissipation The power dissipation for intermittent use is calculated according to the following formula: I rms = I ON2 x t ON t ON + t OFF Ex: RA D 06: current = 4 A t ON = 30 s t OFF = 1 s I rms = 4 2 x The rms current will be 36.7 A.
