JQ220光电耦合器是为家用电器设计的状态传感器,它可以将220V的交流负载工作状态可靠地传送给低压侧,以提高家用电器的安全性。 一、性能特点 1.使用JQ220与交流负载的功率无关,可用存几十千瓦以下的各种家用电器中。 2.高压侧和低压侧均无极性,接线方便。 3.低压侧引出端仅有高阻和低阻两种跳变状态,从而使电路设计简单。 4.高低压侧之间隔离度极好,安全性很高。 5.无明显温升,可连续长期工作,寿命大于10万小时。 6.价格便宜。体积小。 下表是JQ220的性能参数。图1是JQ220外形尺寸和引出线排列。
JQ220 optocoupler is designed for household appliances state sensor, which can be 220V AC load conditions reliably transmitted to the low-voltage side to enhance the safety of household appliances. First, the performance characteristics 1. The use of JQ220 and AC load power has nothing to do, available storage of dozens of kilowatts below a variety of household appliances. 2. High-voltage side and low-voltage side are non-polar, easy to wire. 3. Low-voltage side leads only high impedance and low impedance two transition state, so that the circuit design is simple. 4. Isolation between high and low voltage side is excellent, high safety. 5. No significant temperature rise, continuous long-term work, life expectancy greater than 100,000 hours. 6. Cheap. small volume. The following table is the JQ220 performance parameters. Figure 1 is the JQ220 dimensions and pin arrangement.
