LED Driver for 4W and 8W dimmable replacement bulbs
IW3662 SSL LED驱动器提供通用变压器兼容性和MR16和其他低压照明应用的良好调光兼容性，即使输出功率低至4W。亚博国际官网平台网址
对话框的数字控制技术集成在IW3662中，可以与电子和磁力变压器兼容。IW3662自动检测变压器类型并动态增加峰值加载以锁存变压器，确保与遗留电子变压器的兼容性，这为MR16 LED替换灯泡提供了最大困难。IW3662还通过5％至100％的宽调光范围内检测并与几乎任何调光器一起检测。
Full protection features include Dialog's unique over-temperature protection (OTP) derating, which monitors the temperature inside the sealed LED bulb and seamlessly reduces the drive to the LEDs if the temperature rises above a safe operating threshold, then restores brightness as temperature falls. The iW3662 integrates the temperature sensor and allows the user to configure the OTP thresholds.
