    產品介紹

    ◎ 隨機型固態繼電器移相觸發器模塊(SSR-JKWK)

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


    ◆ 隨機型單相交流固態繼電器具有直流控制端施加信號 , 交流輸出端便立即導通的性能 , 因此當控制信號為交流電網同步的可移相的脈沖信號時 , 負載端便可以實現從 180°到 0°的范圍內電壓的平穩調節 . 隨機型SSR 的移相觸發器模塊 ( 以下簡稱移相觸發器 ) 正是為了方便地應用隨機型 SSR 來調節交流負載電壓而專門設計的 . 移相觸發器的功能是根據控制電壓的大小 , 輸出端產生與電網電壓同步的雙倍電網頻率的從 180°到0°范圍內移相的寬脈沖 , 用以驅動隨機型 SSR, 從而達到移相調壓的目的。

    ◆  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.


    ◎ 單相移相觸發器模塊

    SINGLE PHASE PHASE-SHIFT TRIGGER MODULE

    ◆ 移相觸發器是為方便地調節單相交流電壓而研制的 . 這個系列有共同的部分 : 在同步電壓作用下 ( 此同步電壓還作為模塊的工作電源 ), 經同步相位檢測 , 移相 , 觸發 ,便可以自動控制或電位器手動控制 , 產生 180° ~0°可移相的觸發信號 , 去觸發相應的器件以達到移相調壓的目的。

    ◆ The phase-shift trigger series is developed to conveniently adjust the single phase AC voltage and has the common role: Under the action of the synchronous voltage (which also acts as the operation power of the module), through the synchronous phase-detection circuit, the phase- shift circuit, and the trigger circuit, a phase- shiftable trigger signal (whose phase can be shifted from 180 ° to 0 ° ) will be generated by the automatic control method or manual control method (i.e. the external potentiometer) to trigger the corresponding components to achieve the purpose of phase-shift and voltage-regulation.

    ◎ 隨機型 SSR 移相觸發器的引腳功能

    The ports function of the random conduction type SSR phase-shift trigger module

    ① ②腳同步變壓器的副邊繞組 18VAC 供給移相觸發器電源和同步基準 ;

    ③腳為內部地 ;

    ④腳為輸出端;

    ④腳為輸出端 ;

    ⑤腳為內部地 , 當移相觸發器由外電路自動控制時 , ⑤腳與外電路的地相連 ;

    ⑥腳為控制端,當⑥腳輸入有 0.5V 電壓信號時,④腳輸出端便產生 180° -0°的可移相的寬脈沖(對阻性負載而言);

    ⑦腳為模塊內部產生的 +5V 電壓端,當⑦⑥⑤腳外接電位器手動控制時,⑦腳提供電源,當外電路提供控制信號時,⑦腳懸空。


    The ① and ② ports are connected to the 18VAC secondary winding of the synchronous transformer to offer the power supply and the synchronous reference for the phase-shift trigger;

    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.
