Nikokree It depends on the 2nd circuit you are supplying the voltage on collector of the optocoupler, optocoupler will never transfer the voltages of circuit1 to circuit2, it decreases resistance between your supplied voltages at collector and emitter on the input of circuit2. Mihai on June 10, at q You helped me understand how to use a tester on a optocoupler Thanks. I was wondering if i could just bypass the optcoupler and see if it works. I appriciateā€¦ I tried that emprical method ddatasheet H11B1 optocoupler.

A feedback voltage of 6V , employs current mode control, as shown in Figure 5. An opto-coupler such as the H11AA and shunt , of 2. An opto-coupler such as the H11AA , reference voltage of 2.

This reduces the current through the opto-coupler LED, which also reduces the opto-coupler transistor , soldering defect, the current through the opto-coupler transistor becomes almost zero refer to Figure 5.

KA5Q-series has an internal , optocoupler H11AA and the shunt regulator KA should be designed to provide proper operating current for , 3. A feedback voltage of 6V triggers over load , 5. An opto-coupler such as the H11AA and shunt regulator such as the KA are typically , set voltage.

This reduces the current through the opto-coupler LED, which also reduces the opto-coupler transistor current, thus increasing the feedback voltage Vfb. If Vfb exceeds 3V, the feedback , the opto-coupler transistor becomes almost zero. This current is , acts as a current-sensing resistor. The voltage across R4 appears across resistor R3 and optocoupler , www.

As , C11 and C The output voltage was measured at no load which Original.
