This PLED5 protector provides three methods of increasing the reliability of LED lighting: - If one of the LEDs in an array fails open, this device provides a substitute electronic path so that the array continues to function - It protects against ESD events up to ± 8 kV for contact discharges and ±15 kV for air discharges per the IEC 61000-4-2 electrostatic immunity standard. - It provices protection in the case of accidental revers battery or power connection. 交通照明、广告照明以及跑道照明等对可靠性要求较高的照明功能需要使用PLED5这类设备。
