• 1 pcs New Aluminum Fins Single Phase Solid State Relay SSR 10A to 40A Aluminum Heat Sink Dissipation Radiator Newest Rail Mount mannequin I-50 long×width×high(Mm) eighty × 50 × 50 Scope Scope for the particular load current10ATo40AOf a square single-phase stable state relay Between stable state relay and warmth sink for an calmly covered with thermal grease Solid state relay or module to go with what style of radiator? In fact, not entirely constant correspondence between the two, because the quantity of warmth the cast state relay or module only with the actual load current, whereas the small length of their personal recent level of relations Hair is calculated heat (two kinds): 1, warmth = actual load latest (amps) × 1 watts / amperes The above system is appropriate for single-phase solid state relays, single-phase AC voltage regulator module, R Series solid regulator, and three-phase strong state relay, three-phase AC voltage regulator module, the actual load current should be a three-phase load latest and the actual 2, heat = actual load recent (amps) × 3 watts / amperes The above system is suitable for single-phase full-controlled rectifier module The function of the warmth sink is produced by solid-state relay or module dissipated, but in reality (considering the value factor) to pick the scale of the radiator could be hard to establish the sentence, because the cooling effect is not just related with the scale of the radiator , even went to the ambient temperature (season), air flow (natural cooling or forced cooling and air volume) and the set up density and different points are linked Reference cooling effect: the lowest plate or solid-state relay modules (contact floor with the heat sink) temperature now not exceeding 80 ° Therefore, the actual application can be close to the edge of the solid-state relay or module within the radiator mounting floor (20mm or less) to put in a seventy five ° temperature swap (with a couple of normally closed contacts), the forged state relay or module management signal in sequence this normally closed touch So that after the detected temperature exceeds seventy five °, the normally closed contact tripped off control signal, output became forcibly closed by means of solid-state relay or module to be secure Usually in each part precise current exceeds 50A, installed density, excessive ambient temperature of the place, ideally the temperature swap defense Selection of radiators in addition to considering the above factors, but also consider solid-state relay or module itself can event the quantity of the radiator and radiator mounting space in the cabinet But finally to ensure that even within the worst case, or solid-state relay module baseplate temperature must never exceed 80 ° The manufacturing facility manufacturing of radiator merchandise have the ensuing specifications: YM-I, W, T, G, M, L, H, Y 8 series, for quite a lot of solid-state relay single, one-way change regulator modules, R Series strong state voltage regulators, business grade stable state relays, solid state relays and a variety of three-phase AC strength semiconductor module
