我单位买了一台386计算机和一台LQ-1600K打印机用于办公自动化,为了可靠,同时买了一台交流稳压电源614-AJ,使用一段时间后,计算机损坏,等我们维修时,才发现是稳压电源引起的损坏。 在修好了计算机以后,连上稳压电源和打印机,开机试验,发现交流电流在0.3～0.8A之间变化,稳压电压偏差在15～25V之间变化(电流及电压读数均在614-AJ电表上读得)。当即怀疑是稳压电源有问题,对稳压电源进行检查,重载和轻载试验均未发现问题,稳压效果很好。但联机仍不稳,于是怀疑打印机有问题,另换一台同样的LQ-1600K接入,仍出现故障,后经仔细分析认为:交流稳压器
My unit bought a 386 computer and a LQ-1600K printer for office automation, in order to be reliable, at the same time bought an AC power supply 614-AJ, after a period of use, the computer is damaged, wait for us to repair Found to be caused by the power supply damage. After fixing the computer, connect the regulated power supply and printer, start the test and found that the AC current changes between 0.3 ~ 0.8A, the voltage deviation between 15 ~ 25V (current and voltage readings are in the 614-AJ Meter reading). Immediately suspect that there is a problem with regulated power supply, check the regulated power supply, heavy load and light load test found no problem, the regulator effect is very good. But the connection is still unstable, so I suspect the printer has a problem, the other for the same LQ-1600K access, still fails, after careful analysis that: AC voltage regulator
