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.
