LM317T Voltage Regulator with Pass Transistor

R1200P Voltage StabiliserThe single-phase voltage stabiliser model "S'til'" R1200P is one of the "S'til" series R stabilisers.It has a protective device and a power line disturbances filter. The stabiliser is a desktop block with a display and the line circuit-breaker situated on the front panel.A cable with a standard European plug is used for connecting it to the main.R1200P voltage stabiliser is designed to protect equipment that requires very stable supply voltage with the total electric power of no more than 1200 voltamperes.This can be medical, scientific, or measuring equipment and other expensive devices.R2000 voltage stabiliser has: a toroidal power transformer; natural cooling; discrete output voltage adjustment; a wide input voltage range; high overload capacity; relay-type power keys; high response speed; high stabilising accuracy for output voltage; electric short-circuit and overload protection with automatic release. The stabiliser can work at the rated power load in all bands of the extreme input voltage range.And now I will demonstrate how it works. Here I have a lighthead with 10 lamps. Each has the capacity of 75 Watts. The total load will be 750 Watts.The device is on and now we'll see how it works. Here we go. It's working. All the lamps are on. The load is also quite acceptable. Everything works just fine and I can be sure of the lamps' durability.
