这个稳压器电路见图1,它的输出电压通过1兆欧电位器从50到250伏连续可调.由于调整管BF459的最大集电极耗散功率P_(om)为6瓦(带小型散热器),因此稳压器的最大输出电流为25毫安(输出电压250
The regulator circuit is shown in Figure 1 and its output voltage is continuously adjustable from 50 to 250 V with a 1 MΩ potentiometer. Since the maximum collector dissipation power of the BF459 P_ (om) is 6 W (with a small heat sink ), The maximum output current of the regulator is 25 mA (output voltage 250.)
