The temperature reached are acceptable for the components. These values are in compliance with most of SSRs manufacturers. In a cabinet with a minimum of ventilation or a non permanent current, these values are correct. O The curve "2" gives the limits of the product according to EN60947-4-3 with a maximum rise temperature of 50C (@40C) for a permanent working and in air calm ( test during 8 hours). O For a non permanent current, you can calcule the average power = Pd x duty cycle and check the rise temperature : Tj = Pd x Rthj/a (Pd and Rthj/a are given page 2). The junction temperature must not exceed 125C at the maximum ambient temperature.The maximum current is limited to the size of the alternistor = 25A. O The thermal constant (Cth) of the product is 7 minutes. That means the rise temperature is only 63% of the stabilized temperature after a running time of 7 minutes. 25 20 S/CLP/SIL842170/B/21/04/2004 page 3 / 4/GB 1 2 15 I(A) 10 5 0 0 5 10 15 20 25 30 35 40 45 50 55 60 65 70 75 80 85 T ambient (C) fig 2 Overload current .

Always use in conjunction with an adapted circuit breaker with isolation feature or a similar device in order to ensure a reliable isolation in the event of wrong function and when the relay must be insulated from the mains (maintenance ; if not used for a long duration ...).

O L S/CLP/SIL842170/B/21/04/2004 page 4 / 4GB For the output terminals, the wire cross sections must be adapted to the load current and to the overcurrent protection device characteristics. The relay rated voltage must be adapted to the mains rated voltage.

Power 1x(1,5-->16) 1 x(1,5-->10) L = 10mm Pozidriv2/ 0,8x5,5 (1x6) Mounting Warning : only in vertical position. The user should protect heat sensitive materials as well as persons against any contacts with the heatsink. For non vertical mounting , the load current must be 50% lower than the rated one . For a good cooling, the SSR needs an air convection. Less convection air produces an abnormal heating. Keep a distance between the upper SSR and the lower SSR. In case of no space between two SSR ( zero space between two SSRs) , please reduce the load current. For further details refer to below : O O Derating current with no space between SSRs AC-51 nominal currents are given with a space of 22,5mm between each SSR, for a permanent current during a minimum time of 8 hours in air calm according to IEC60947-4-3. In case of non permanent currents or in case of SSRs are mounted with no space, you must check the heatsink temperature never exceed 90C. When the SSRs are mounted side to side ( no space between each relay) a derating current of 25% must be take into account. A forced cooling ( fan inside the cabinet) improves significantly the thermal performances. vertical position 80mm Typical application : LOADS SIL product is designed mainly for AC-51 resistive load. AC-53 motor current are also given . For other loads, check the inrush current at turn ON and possible overvoltages at turn OFF or consult us : * AC-55b : Incandescent lamps : Inrush current is generally 10 times In during few 10ms. So limit the nominal current at about 10A. * AC-55a : Electric discharge lamp : These loads often have overcurrent at turn ON and overvoltage at turn OFF, so we advise to use 400VAC SSR on 230VAC mains. * AC-56a : Transformers loads: Very high inrush current up to 100 times In . We advise to use random SSR. * AC-56b : Capacitors loads: Very high current at turn ON and overvolatge at turn OFF, please consult us with 1600V peak SSR with high inrush current. 1~ Fuse Fusible Protection : To protect the SSR against a short-circuit of the load , use a fuse with a I2t value = 1/2 I2t value specified page 2. A test has been made with FERRAZ fuse ( see page 2). It is possible to protect SSR by MCB ( miniature circuit breaker). In this case, see application note ( SSR protection) and use a SSR with high I2t value (5000A2s minimum) L1 EMC : O Immunity : We give in our data-sheets, the immunity level of our SSRs according to the main standards for this type of products : EN61000-4-4 &5. You can see the high immunity level in comparison with the products on the market. O Emission: SSRs are complex devices which must be interconnected with other equipment (loads, cables,etc.) to form a system. Because the other equipment or the interconnections may not be under the control of celduc, it shall be the responsibility of the system integrator to ensure that systems containing SSRs comply with the requirements of any rules and regulations applicable at the system level. The very low zero cross voltage (<10V) improves the conducted emission level in comparison with most of SSR on the market with zero cross voltage higher than 25V. Consult celduc laboratory which can make some tests in your application.
