DSH 729/737（IEC 60065/60950-1）覆蓋散熱片的外殼溫升/器具插座溫升

DSH 729

Subject: Temperature limit of main enclosure over heat sink

Question:

Can the 65 ° K temperature rise limit be applied for the surface of the main enclosure covering an internal heat sink in the same way as is applied for vacuum tubes following DSH-566?

Decision:

The 65 ° K rise limit may be applied to the enclosure covering an internal heatsink, if:

? the symbol (IEC60417, 5041) is marked on or adjacent to the heated area of the surface of the enclosure, and

? the minimum distance over the surface of the product between this area and any control intended to be operated during use is 150 mm or greater, and

? the instruction manual gives information regarding it.

問題：

覆蓋內(nèi)部散熱器的外殼表面溫升是否可以像DSH 566號決議的真空管一樣使用65K限制？

決定：

65K限制適用于覆蓋內(nèi)部散熱器的外殼，前提是:

1、在外殼表面受熱區(qū)域或其附近有標(biāo)記符號（IEC60417, 5041）

2、在使用過程中，該區(qū)域與產(chǎn)品任意操作面的最小距離為150毫米或更大

3、說明書中提供了相關(guān)說明

DSH 737

Subject: Application of IEC 60320-1 type appliance inlet

Question:

Does DSH-548 apply to end products only, or to other equipment, such as built-in power supplies, where the appliance inlet is likely to serve as (PLUGGABLE EQUIPMENT TYPE A) means for connection to the AC MAINS SUPPLY?

Decision:

DSH-548 applies to all PLUGGABLE EQUIPMENT TYPE A where the appliance inlet is used as means for connection to an AC MAINS SUPPLY.

問題：

DSH 548號決議是僅適用于終端產(chǎn)品，還是適用于其他設(shè)備，如內(nèi)置電源，其中器具輸入插座可能作為（A型可插式設(shè)備）連接到交流電網(wǎng)電源的方式？

決定：

DSH 548號決議適用于所有A型可插式設(shè)備，其中器具輸入插座用于連接到交流電網(wǎng)電源。
