The OPTEK broad line of optocouplers gives design engineers a wide selection to choose from. Typical isolation voltage is 2500, 3750, and 5000 volts, (RMS) making the devices ideal for most power system isolation requirements. Most products have selectable CTR ranges. Product is available with either analog or digital output.
