LM317T Voltage Regulator with Pass Transistor

LR1100 Power ConditionerGreat. It all works... LR1100 power conditioner combines two devices - a voltage regulator and a power supply filter. Voltage regulator is a device which automatically converts the current increased or reduced voltage into stable 220 V. Such device protects audio and video appliances, personal computers, computer peripheral devices, office equipment, and home appliances against reduced or increased supply voltage, overvoltage, surge voltage, and high-frequency interferences. Home electronics are designed to work from supply voltage of 220-230 V. But true voltage in the network often fluctuates from 150 to 260 V. In the evening a power grid experiences the biggest load, thus voltage is minimal. There are different reasons for voltage steps. This can be network overload, old transformers, and wrong wiring. LR1100 power conditioner will help you solve these problems. The device has several advantages over other appliances. It has an extended voltage regulation range, an emergency 2-level shutdown system, an increased suppression of pulse and high-frequency interferences, a 2-level current protection, and increased overload capacity.Here is what we have on the front panel of LR1100. A power switch with an indicating light - the LED which indicates proper operation. There is also a thermobimetallic protector which automatically cuts off the device from a power grid in case of exceeding current consumption. And there is also an indicator of input and ...
