WebOct 25, 2024 · Optocouplers contain both a light-emitting diode (LED) and a photo detector. Current flowing through the LED results in a proportional current flowing in the photo detector. The current transfer ratio (CTR) is the current gain from the LED to the photo detector, and typically has a very wide tolerance. WebMar 24, 2024 · The factors that may vary the CTR depends on the instantaneous specifications of input and output supply voltage and current to the device.
