◆使用注意事项 Application attentions

●控制电压和工作电压要求稳定，波动系数应该保证在10%之内，接线时应注意固态继电器的极性，以防接错而造成固态继电器永久性损坏。固态继电器应安装在远离热源散热条件好的地方，若环境温度过高，或者散热条件不好时，应加大工作电流余量，以保持固态继电器能均匀良好的散热。在安装固态继电器时，紧固件应扭紧，防止松动而增大接触电阻导致发热过大，底板与散热器之间也应均匀的涂上一层导热硅脂，保持固态继电器能均匀良好的散热。
●Control voltage and working voltage must be stable, the coefficient of fluctuation should guarantee in 10%, when wiring should pay attention to the solid state relay’s polarity to avoid wrong connection causing solid state relay permanence Damage. SSR should be mounted away from origin of heat and good radiating conditions.In the case that the ambient temperatures is too high or bad radiating condition, it should increase the current margin to ensure SSR good working.In the case that the ambient temperatures is too high or bad radiating condition, it should
increase the current margin to ensure SSR good working. SSR can be even and good radiating. When mounting SSR, fastener must be tightened to prevent increasing resistance caused by screw loosing. Even spreads heat conduction silicon, maintains the solid state relay can be even good radiation.
●应采用相应的过流与过压保护措施。过流保护可选用响应时间为10μS的快速熔断器，熔断器的大小可选择用实际工作电流的1.2-1.5倍；过压保护可采用RC阻容吸收回路和压敏电阻，本系列固态继电器已全部内置RC阻容吸收回路，压敏电阻可按工作电压电流的大小来选择，220V电路电压可选用430-470V的压敏电阻，380V电路电压可选用750-820V的压敏电阻，压敏电阻的通流容量可根据电流的大小来选择。
●Should use the corresponding overflow and the overvoltage protection measure.Overflow protection may select the fast fuse that response time is 10μS. Fuse size choose the practical work current 1.2-1.5 times.Overvoltage protection may use RC resistance-capacitance absorbing circuit and varistor. This series SSR has built in RC resistance-capacitance. Varistor choosing may according to the working voltage and current. 220V voltage select the varistor of 430-470V, 380V voltage select the varistor of 750-820V,the varistor discharge current capacity choose according to the current size.

◆固态继电器的散热及散热器的选择 Solid state relay’s radiating and heat sink choice

●由于固态继电器内开关器件本身内阻的作用，在其导通时都会产生一定热量。因此要保证固态继电器正常工作必须要有良好的散热条件如：自然冷却、散热冷却、散热器加风冷却等。5A以下可采用自然冷却， 10A以上需加散热器冷却， 40A以上则要加风扇强冷。
●Because the inside switch components have interface resistance function, solid state relay can have certain heat in its breakover time. Therefore guarantee solid state relay normal work must have the good radiation condition. For example: Natural cooling, radiation cool, the radiator to add wind cooling and so on. Below 5A may use the natural cooling, above 10A must add the radiator to cool, above 40A needs to add the ventilator strongly cold.
●散热器的效果不但跟散热器的大小有关，还跟环境温度（季节）、通风条件及安装紧密度都有关系。散热效果参考标准：使固态继电器的底板温度不超过75℃为准，实际应用过程中可在靠近固态继电器底板的散热器上安装一只70℃的温度开关（常闭型）串联在控制回路里，当散热器温度超过阀值时就会断开控制回路，从而保护固态继电器及设备，尤其是在实际电流大、安装密度大、环境温度高的情况下。除此之外还要考虑固态继电器本身是否与选用的散热器匹配，以及散热器在机柜中的安装空间，确保即使在最恶劣的情况下固态继电器底板的温度不超过75℃。
●Not only radiator’s effect related with the size, but also with the ambient temperature , the well ventilated condition and installment tightness has the relations. Radiation effect reference standard: make the solid state relay’s bottom board ’s temperature not to surpass 75℃æ it may install a 70℃æ( NC model) to connect in the control loop, when the radiator temperature surpasses the valve value will separate the control loop, thus protection solid state relay and equipment, particularly in the actual large current , big mounting density and high ambient temperature situation. In addition, need to consider whether solid state relay itself match with the radiator , as well as radiator’s installment space in cabinet, guaranteed that the solid state relay’ s board temperature does not surpass 75℃æin the worst situation.
●本公司有一系列的散热器规格可供选择，但每一型号的固态继电器不是一定要配唯一规格的散热器，两者并没有完全一致的对应关系，固态继电器的发热量只跟负载的实际电流有关，而与本身的电流等级不完全一致。（发热量计算公式：发热量=实际负载电流×1.5瓦/安）
●Our company has many series radiator specification for choice, but each model SSR is not to certainly match the only model radiator,they both have not completely corresponding relationships. Solid state relay’ s Calorific capacity only related with the actual load current, not completely consistent with current rank. (Calorific capacity formula: Calorific capacity = actual load current×1.5 tile/amp)
