Many hams designers in recent times we have to dealing with electronic devices, focusing on the powered side the vehicle network. It is a powerful receiver and radio stations, as well as special the electronic system. Such devices consume a current of about 3 amps, so when they operation in stationary conditions, the problem arises of the power supply.
To solve it will help rectifier WU-1" of the Ulyanovsk instrument-making plant designed for charging car rechargeable batteries. The fact that WU-1", in fact, is a half of the device. It has enough power (up to 100W), Can only add to its stabilizing attachment for a voltage of 12 V At currents up to 6 A. the Prefix performed according to the classical scheme (Fig. 3.17) stabilizer the voltage of the non-deficient parts of the low cost.
