◎ 隨機(jī)型固態(tài)繼電器移相觸發(fā)器模塊(SSR-JKWK)
RANDOM CONDUCTION SOLID STATE RELAY PHASE-SHIFT TRIGGER MODULE (SSR-JKWK)
◆ 隨機(jī)型單相交流固態(tài)繼電器具有直流控制端施加信號(hào) , 交流輸出端便立即導(dǎo)通的性能 , 因此當(dāng)控制信號(hào)為交流電網(wǎng)同步的可移相的脈沖信號(hào)時(shí) , 負(fù)載端便可以實(shí)現(xiàn)從 180°到 0°的范圍內(nèi)電壓的平穩(wěn)調(diào)節(jié) . 隨機(jī)型SSR 的移相觸發(fā)器模塊 ( 以下簡(jiǎn)稱移相觸發(fā)器 ) 正是為了方便地應(yīng)用隨機(jī)型 SSR 來調(diào)節(jié)交流負(fù)載電壓而專門設(shè)計(jì)的 . 移相觸發(fā)器的功能是根據(jù)控制電壓的大小 , 輸出端產(chǎn)生與電網(wǎng)電壓同步的雙倍電網(wǎng)頻率的從 180°到0°范圍內(nèi)移相的寬脈沖 , 用以驅(qū)動(dòng)隨機(jī)型 SSR, 從而達(dá)到移相調(diào)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.
