Solid state relay or module to go with what type of radiator? In fact, not entirely consistent correspondence between the two, because the amount of heat the solid state relay or module only with the actual load current, whereas the small size of their own current level of relations.
Hair is calculated heat (two kinds):
1, heat = actual load current (amps) × 1.5 watts / amperes
The above formula is suitable for single-phase solid state relays, single-phase AC voltage regulator module, R Series solid regulator, and three-phase solid state relay, three-phase AC voltage regulator module, the actual load current should be a three-phase load current and the actual .
2, heat = actual load current (amps) × 3.0 watts / amperes
The above formula is suitable for single-phase full-controlled rectifier module.
The role of the heat sink is produced by solid-state relay or module dissipated, but in fact (considering the price factor) to select the size of the radiator can be difficult to determine the sentence, because the cooling effect is not only related with the size of the radiator , even went to the ambient temperature (season), ventilation (natural cooling or forced cooling and air volume) and the installation density and other factors are related. Reference cooling effect: the bottom plate or solid-state relay modules (contact surface with the heat sink) temperature not exceeding 80 °. Therefore, the actual application can be near the edge of the solid-state relay or module in the radiator mounting surface (20mm or less) to install a 75 ° temperature switch (with a pair of normally closed contacts), the solid state relay or module control signal in series this normally closed contact. So that when the detected temperature exceeds 75 °, the normally closed contact tripped off control signal, output was forcibly closed by solid-state relay or module to be protected. Usually in every phase actual current exceeds 50A, installed density, high ambient temperature of the place, preferably the temperature switch protection.
Selection of radiators in addition to considering the above factors, but also consider solid-state relay or module itself can match the volume of the radiator and radiator mounting space in the cabinet. But in the end to ensure that even in the worst case, or solid-state relay module baseplate temperature must not exceed 80 °.
The factory production of radiator products have the following specifications: YM-I, W, T, G, M, L, H, Y eight series, for a variety of solid-state relay single, one-way exchange regulator modules, R Series solid state voltage regulators, industrial grade solid state relays, solid state relays and a variety of three-phase AC power semiconductor module.
