 使用说明

 

 

请您在使用开关电源前认真阅读下列有关说明:

1、 使用电源前,首先确认您所要求的输入电压规格(110vac、220vac或100v~264vac)与所用电源的标称值是否相符。

2、 接线时请注意电源接线端子上方的符号标识,其含义如下:

ln—单相交流输入端

〨(fg)—保护地(接系统外壳或大地)

g—表示输出地,多路时有不共地的情况分别用g1、g2、g3…..来表示不同的地。

-v、+v—表示正负电压输出,多路输出时分别用v1、v2、v3……表示各路输出。

adj—主回路输出电压调节电位器,一般可调范围为±10%。

3、 对于大功率的电源,一般均有两个或两个以上的+v、-v输出端子,实际上所有的+v端子或所有的-v端子,它们在内部是并接相通的,端子的这种排列方式只是为了用户接线方便而已。用户在接线时请将各路端子均匀地接入负载。

4、 金属外壳电源必须将电源上的(fg)端子可靠接大地,以保证使用的安全性和减少干扰,不可将开关电源金属壳体接在零线上以防触电。

5、 多路输出的电源分为主、辅路输出,主路输出特性优于辅路,一般情况下输出电流大的一路为主路。为了保证输出负载调整率和输出动态等指标,一般要求每路输出至少带10%的负载,若只用辅路而不用主路,主路一定要加假负载(500ma以上)。

6、 对于输出为高压(大于36v)的电源,有必要重申对安全的重视。使用过程中或停电后十分中内不可触及高压危险区。

7、 电源频繁开关将会影响其寿命。对于雷电多发区、山顶应考虑防雷设施。

8、 对于双路正负输出应优先考虑使用对称负载。

9、 要在规定的环境条件下使用开关电源。温度是影响电源寿命的主要因素,在安装电源时应有利于电源散热,如电源自身带有轴流风机时,进风侧和出风侧须至少留有100mm的空间。

10、在使用容性负载或感性负载时应考虑负载启动电流对电源的影响(一般情况下启动电流为正常电流的数倍),为防止电源因过流保护而误动作,应适当加大电源的功率要求。

11、在电源安装完毕通电前,请再次确认输入电压、输出及各端子连线的正确性以免损坏用户设备。
