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. Shall you have any questions regarding this engineering change, please contact MEAN WELL sales representative.
 
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.
