苏州电工仪器厂生产的614系列电子交流稳压器在电网电压波动或负荷变动时能自动进行调整,供出稳压精度较高的220V交流输出电压.因此,该产品获得相当广泛地使用.仅我们单位就拥有614系列各种交流稳压器50余台.在分析室许多进口的电子精密分析仪器如直读光谱仪、极谱仪和原子吸收仪等等均用该稳压器供电.但这种稳压器有一个较严重的缺点,其整机自动电压调整电路的参考元件2D2P钨丝二极管易于损坏.一旦2D2P管烧坏,
The Series 614 AC voltage regulators manufactured by Suzhou Electrical Instrument Factory can automatically adjust to fluctuations of the grid voltage or load to provide a 220V AC output voltage with high regulation accuracy. Therefore, the product is widely used. The unit has 614 series of various exchanges and stabilizers more than 50. In the analysis room many imported electronic precision analytical instruments such as direct reading spectrometer, polarography and atomic absorption, etc. are used to power the regulator. Regulator has a more serious shortcomings, the automatic voltage regulation circuit of its reference element 2D2P tungsten diode easy to damage once 2D2P tube burned out,
