Product Description
The DBW/SBW series power stabilizer mainly consists of such parts as column varitran, compensator transformer, sampling control circuit, protection control circuit and low-speed synchronous motor mechanism. It case of unstable voltage of mains supply or fluctuations caused by the user¡¯s load changes, the sampling circuit will process the voltage signal and send it to the synchronous motor which then will drive the column varitran¡¯s carbon brush to move up and down to ensure the stable output voltage. It¡¯s featured by its big capacity, low loss, high efficiency, wide voltage stabilizing range, high precision. Powerful protection, reliable operation, easy use and maintenance and so on. SBW 150KVA power stabilizer
Products application
Voltage regulators or Voltage stabilizer are used to compensate for voltage fluctuations in mains power. Large regulators may be permanently installed on distribution lines. Small portable regulators may be plugged in between sensitive equipment and a wall outlet. Automatic voltage regulators are used on generator sets on ships, in emergency power supplies, on oil rigs, etc. to stabilize fluctuations in power demand. For example, when a large machine is turned on, the demand for power is suddenly a lot higher. The voltage regulator compensates for the change in load. Commercial voltage regulators normally operate on a range of voltages, for example 150?240 V or 90?280 V. Servo stabilizers are also manufactured and used widely in spite of the fact that they are obsolete and use out-dated technology.
Products advantages
This product has such advantages as big capacity, low loss, high efficiency, wide voltage stabilizing range, high precision, powerful protection and reliable operation. Also it¡¯s provided with protections from open phase, output overvoltage, under-voltage and over current.
