SBW, DBW series compensated power regulator

SBW, DBW series of compensation for electricity regulator, is the first in Western Europe in the early 1980s the emergence of a new energy-efficient power regulator. 90s are widely used throughout the field of economy. It can when the external power supply network voltage fluctuations or load changes caused by fluctuations, can automatically maintain output voltage stability, to ensure the normal operation of your electrical equipment.

This series of products compared with other forms of regulators, with large capacity, high efficiency, no waveform of distortion, stable voltage regulation, load applied widely, can withstand instantaneous overload, long-term continuous operation with overvoltage, undervoltage, over-current protection devices. and small size, light weight, easy to use, reliable operation, easy maintenance and so on. It can be widely used in industry, agriculture, pay electricity, military, telecommunications, scientific research, culture and other fields of large mechanical and electrical equipment, metal processing equipment, production lines, construction equipment, elevators, medical equipment, computer room, computer-controlled equipment, embroidery and textile equipment, air conditioning, radio and television, hotels and home appliances, lighting and all the places to be regulated.

working principle

The regulator by the compensation circuit, a voltage detection circuit, servo motor control circuit and decelerated rotation mechanism, the main circuit switching operation of the circuit, voltage, current measurement and protection circuit. Regulator electrical schematic shown in Figure 1.

Voltage compensation circuit consists of contact voltage regulator with compensation transformer T1 composition T2. ​​Contact voltage coil connected to the output of the regulator, two brush pick compensation transformer primary winding, compensation transformer secondary coil in series in the main loop, which compensation principle: When the input voltage U1, change ΔU1, if the offset voltage UC and corresponding changes ΔUC ΔU1 = ΔUC, output phase voltage U2 can remain unchanged compensation voltage UC regulation is based on change in output voltage to the voltage detection unit. a signal to control the servo motor rotation, deceleration and drive mechanism driven by the contact voltage regulator brush sliding contact with the regulator adjusted two brushes to change the compensation voltage automatically maintaining output voltage regulation.

Features
