◎ 随机型固态继电器移相触发器模块（SSR-JKWK）

RANDOM CONDUCTION SOLID STATE RELAY PHASE-SHIFT TRIGGER MODULE (SSR-JKWK)

◆ 随机型单相交流固态继电器具有直流控制端施加信号 , 交流输出端便立即导通的性能 , 因此当控制信号为交流电网同步的可移相的脉冲信号时 , 负载端便可以实现从 180°到 0°的范围内电压的平稳调节 . 随机型SSR 的移相触发器模块 ( 以下简称移相触发器 ) 正是为了方便地应用随机型 SSR 来调节交流负载电压而专门设计的 . 移相触发器的功能是根据控制电压的大小 , 输出端产生与电网电压同步的双倍电网频率的从 180°到0°范围内移相的宽脉冲 , 用以驱动随机型 SSR, 从而达到移相调压的目的。

◆  The random conduction type single phase AC solid state relay has such a function that once a signal applied the DC control terminal, the AC output terminal will be turned on immediately. Therefore, if the control signal is a phase-shiftable pulse signal synchronized by the AC power grid, the voltage phase on the load terminal can be adjusted smoothly from 180 ° to 0 ° . The phase-shift trigger module of the random conduction type SSR (hereinafter referred to as the phase-shift trigger) is specially designed for the random conduction type SSR to conveniently adjust the AC load voltage. The function of the phase-shift trigger is to generate a wide pulse (with the synchronization with the power grid voltage, and the frequency twice of the power grid frequency, and the phase can be shifted from 180 ° to 0 ° ) on the output terminal according to the magnitude of the control voltage, to drive the random conduction type SSR to achieve the purpose of phase-shift and voltage-regulation.

The ③ port is the internal common ground terminal The foot is the output end; 

The ④ port is the output terminal;

The ⑤ port is the internal common ground terminal. If the phase-shift trigger is controlled by the external automatic control circuit, the ⑤ port will be connected to the ground of the external control circuit;

The ⑥ port is the control terminal. When there is a 0.5V voltage signal inputted to the ⑥ port, a wide pulse (whose phase can be shifted from 180 ° to 0° ) will be produced on the output terminal ④ port (for resistive loads);

The ⑦ port is the +5V voltage terminal generated inside the module. If the  ⑤ ,  ⑥ ,  ⑦ ports are connected to the external potentiometer to apply the manual control method, the ⑦ port acts as the power supply for it; if the control signal is provided by external control circuit to apply the automatic control method, the ⑦ port should be left floating.
