page 4 /5 GB Thermal specifications. The curve "" gives the limits of the product. 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. The curve "" gives the limits of the product according to EN694743 with a maximum rise temperature of 5 C (@4 C) for a permanent working and in air calm ( test during 8 hours). 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 )). The junction temperature must not exceed 5 C at the maximum ambient temperature. The maximum current is limited to the size of the thyristors = 5A. 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.

Drill for vertical can be adjusted,7mm 88±mm Warning! semiconductor relays don't provide any galvanic insulation between the load and the mains. 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...).

Connections. celpac 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. celpac use screw clamp connections. Mounting 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 5% 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 : Derating current with no space between SSRs AC5 nominal currents are given with a space of,5mm between each SSR, for a permanent current during a minimum time of 8 hours in air calm according to IEC694743. In case of non permanent currents or in case of SSRs are mounted with no space, you must check the heatsink temperature never exceed 9 C. When the SSRs are mounted side to side ( no space between each relay) a derating current of 5% must be take into account. A forced cooling ( fan inside the cabinet) improves significantly the thermal performances. Typical application : LOADS SILD product is designed mainly for AC5 résistive load. AC53 motor current are also given. For other loads, check the inrush current at turn ON and possible overvoltages at turn OFF or consult us : * AC55b : Incandescent lamps : Inrush current is generally times In during few ms. So limit the nominal current at about 5A. * AC55a : Electric discharge lamp : These loads often have overcurrent at turn ON and overvoltage at turn OFF, so we advise to use 4VAC SSR on 3VAC mains. * AC56a : Transformers loads : Very high inrush current up to times In. We advise to use random SSR. * AC56b : Capacitors loads : Very high current at turn ON and overvolatge at turn OFF, please consult us with 6V peak SSR with high inrush current.

A test has been made with FERRAZ fuse ( see page ). 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 I t value (5A s minimum). L Diag L Diag EMC : Immunity : We give in our datasheets, the immunity level of our SSRs according to the main standards for this type of products : EN644 &5. You can see the high immunity level in comparison with the products on the market. 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 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.. Consult celduc laboratory which can make some tests in your application.
