产品变更通知：IRM / MPM / WDR / SDR/ MDR / DRA / DRS / SCP 端子台变更

近年来，由于疫情的影响，我们面临着物料供应短缺和延迟的情况。为确保供应链稳定，MEAN WELL 对端子板生产采取了多渠道采购的方式。

IRM / MPM / WDR / SDR / MDR / DRA / DRC / DRS / SCP 等系列产品之间有一些微小的差异，包括外观，颜色，扭矩等方面的差异（详见下表）。

自2023年5月起，新的生产将会包括上述的更改，但请注意会有新旧版本并行出货。销售价格将保持不变，如果您对此事有任何疑问或关注，请联系MEAN WELL的代表以获取更多信息。
