本文介绍了一种高稳定性多功能的氘灯恒流电源,其电流调整率达到6.5×10~(-6),漂移达到5.0×10~(-5)/hr。它具有多功能的特点,既可满足各类氚灯使用的供电要求,又可满足各类氘灯科研和生产工作中测试工作的要求;既可与使用氘灯(或氢灯)作光源的各类光学式分析仪器(如紫外光谱仪、HPLC、FIA等仪器)配套,又可单独使用在需要50～450mA直流恒流电源的各类仪器装置中。文中简单介绍了该恒流电源的电路结构、工作原理、主要技术指标。并对几个有关的问题进行了初步探讨。
This paper introduces a high stability multifunctional deuterium lamp constant current power supply, the current regulation rate of 6.5 × 10 -6, drift reached 5.0 × 10 -5 / hr. It has the characteristics of multi-purpose, not only meet the power requirements of various types of tritium lamps, but also meet the requirements of various deuterium lamp research and production work; both with the use of deuterium (or hydrogen) light source Various types of optical analytical instruments (such as UV spectrometer, HPLC, FIA and other equipment), but also alone in the need 50 ~ 450mA DC constant current power supply of various types of equipment. The article briefly introduces the circuit structure of the constant current power supply, working principle, the main technical indicators. And conducted a preliminary discussion on several related issues.
