새로운 안전규격인 IEC62368의 업그레이드에 맞추어 LRS-200-48과 LRS-350-48 제품의 회로 설계를 변경하여 "과부하 보호(OLP), 과전압 보호(OVP), 과온도 보호(OTP)에 대해 기존 히컵-자동복구 보호동작에서 셧다운 및 래치오프 출력차단-재전원 켜기"로 조정이 되어 공지합니다.
해당 보호동작의 변경은 2019년 11월 26일 이후 생산분부터 적용되며 LRS-200-48 & LRS-350-48제품에 국한되어 적용되고 나머지 제품들은 기존 보호동작이 유지됩니다.
The all-purpose industrial standard power supply, LRS family, has completed the EN62368 safety upgrade in October 2019. To fulfill the latest safety regulation, tthe circuit design of LRS-200-48 and LRS-350-48 was changed, adjusting the protection methods such as Over Load Protection (OLP), Over Voltage Protection (OVP), and Over Temperature Protection (OTP) to“ shut down and latch off o/p voltage, re-power on to recover.” Other LRS-200/350 3.3~36V models remain the Hiccup mode protection. (Show as fig.1) This change only shows the difference during error state, while under normal working circumstances; all LRS series can maintain high quality and stable output as usual.

The following standard product series are upgraded to the new version after the production dated 2019/11/26(production lot.: W1912C). MEAN WELL will fully absorb the costs incurred from this upgrade and will not increase the product price.
