A simple power control of the load can be made from industrial phase speed controller electric BUE-ЗВР1. This device has small dimensions 50×55 mm, excluding handles and a reversible switch. Its purpose is to regulate the speed commutator AC motors.
As for the control units drill (BUE) in General, they are made on the same principle, and contained within a multi-turn variable resistor and the triac. As elements of “obiski” in the circuit there is a dual non-polar capacitor (type K73-53-3 or similar) with tap from mid point – it is needed to smooth out surges through the field winding drills. Sales are like him (in appearance and markings) industrial instrument applied to the body marking BUE, UAH (voltage regulator), etc.
The maximum voltage to the load is supplied when the variable resistor (included in the scheme of connection) minimum resistance. In some types BUE (as in BUE-ЗВР1) provides a reverse switch to reverse the motor rotation. In the marking device indicated by the letter “R”. Marking the numbers after the abbreviations BUE corresponds to the maximum current in the load which it is capable of this regulator. For example, GRN-1-220 is designed for current 1 a and voltage 220 V.
In other related devices, such as BUE-1, reverse mode no, but the scheme include all BUE identical. The control voltage supplied to the load, is due to the delay of opening of the triac with respect to the instant of transition of the voltage (sine wave) through “0”.
