产物先容

◎ 产物特点 Product features

◆ 固态继电器或模块要配甚么型号的散热器呢?实在二者之间并不一个完整分歧的对应干系,由于固态继电器或模块的发烧量首要跟所驱动的负载的现实电流有关,而与自身的电流品级巨细干系不大。

◆ 发烧量的计较公式:

1. 发烧量 = 现实负载电流 ( 安倍 ) * 1.5 瓦 / 安倍以上公式合适于单相固态继电器 , 单订交流调压模块 , R系列固态调压器 . 而对三相固态继电器 , 三订交流调压模块 , 实在际负载电流应为现实负载电流之和。

2. 发烧量 = 现实负载电流 ( 安倍 )*3.0 瓦 / 安培以上公式合适于单相全控整流模块

◆ 散热器的感化便是把固态继电器或模块发生的热量散收回来 , 但现实上 ( 斟酌到价钱身分时 ) 挑选散热器的巨细很难用一句话就可以肯定 , 由于散热器结果岂但跟散热器的巨细有关 , 还跟环境温度 ( 季候 ), 透风前提 ( 天然冷却或逼迫冷却及风量巨细 ), 和装置密度等身分均有关 . 散热结果的参考规范 : 使固态继电器或模块的底板 ( 与散热器打仗面 ) 温度不跨越 80℃ . 是以现实利用中可在散热器装置面接近固态继电器或模块的边缘块(20mm 之内 ) 装置一只 75℃的温度开关 ( 带一对常闭触点 ), 把固态继电器或模块的节制旌旗灯号串入这对常闭触点 , 如许当检测点温度跨越 75℃时 , 常闭触点跳开 , 堵截节制旌旗灯号 , 逼迫封闭固态继电器或模块的输入 , 使其获得掩护 . 普通在每相现实电流跨越 50A, 装置密度大 ,环境温度高的处所 , 最好接纳温度开关掩护。

◆ 选用散热器除斟酌上述身分外 , 还要斟酌固态继电器或模块自身体积与散热器可否相配 , 和散热器在机构中的装置空间 . 但终究要保障在卑劣环境下 , 固态继电器或模块的底板温度不跨越 80℃。

◆本厂出产的散热器产物首要有以下规格 :


MG-I, MG-W, MG-T, MG-L, MG-H, MG-F,MG-Y 七大系列 , 合适于各类单相固态继电器 , 单订交流调压模块 , R 系列固态调压器 , 产业级固态继电器及各类三订交流固态继电器。

◆ How to choose the right heat sink for solid state relays or modules?In fact, the model of the heat sink does not one-one correspond to the model of the solid state relay or module. The heat generated by the solid state relay or module is mainly related to the actual current of the load, instead of its own rated current specification.

◆ Heat calculation formula:

1. Heat = Actual load current (Amps) * 1.5 W/Amps The above formula is suitable for single phase solid state relays, single phase AC voltage regulator modules, and R series solid state voltage regulators. For three phase solid state relays and three phase AC voltage regulator modules, the actual load current should be the sum of the actual load currents.2. Heat = actual load current (Abe) * 3.0 watts/Abe formula is suitable for single-phase full control rectifiermodule.

2. Heat = Actual load current (Amps) * 3.0 W/Amps The above formula is suitable for single phase fully-controlled bridge rectifier module.

◆ The role of the heat sink is to dissipate the heat generated by the solid state relay or module, but in reality (considering cost factors), the choice of heat sink size is difficult to determine simply.

Because the effect of the radiator is not only related to the size of the radiator, but also to the ambient temperature (season), ventilation conditions (natural / forced cooling, and ventilation volume), and installation density. Heat dissipation reference standard: The temperature of the bottom plate (the side in contact with the heat sink) of the solid state relay or module does not exceed 80  ° C. In practical applications, we recommend installing a 75 ° C temperature switch (with a pair of normally closed contacts) on the heatsink mounting surface near the edge of the solid state relay or module (within 20mm), and connecting the control signals of the solid state relay or module in series with the normally closed contacts. Thus, when the temperature of the detection point exceeds 75 ° C, the normally closed contact trips and cuts off the control signal, and the output of the solid state relay or module is forcibly turned off to be protected.

Generally, if the solid state relay or module is installed to the place with each phase of the actual current exceeding 50A, high installation density, and high ambient temperature, it is better to apply a temperature switch protection. 


◆ In addition to considering the above factors, it is also necessary to consider whether the volume of the solid state relay or the module itself and the installation space of the heat sink in the equipment matches the parameters of the heat sink.

◆ The following is the series of the heat sink mainly produced by our company:

MG-I, MG-W, MG-T, MG-L, MG-H, MG-F, MG-Y. These seven series are suitable for a variety of single phase solid state relays, single phase AC voltage regulator modules, R series solid state voltage regulators, industrial solid state relays and various three phase AC solid state relays.
