DOER Power Tech., wish to accommodate for most individual specific requirements with bespoke made solutions .
IGBT Three Phase Static Voltage Stabilizer
Voltage fluctuations are very common in the isolated and remote areas, the main purpose of a voltage stabilizer is to regulate the output voltage that feeds the load equipment connected to it be equivalent to the ideal power supply, all electric equipment requires a power supply which is maintained within certain limits. Too lower and too higher voltgage fluctuations from utility power supply, results in the load equipment’s malfunction and could be damaged in a lng run, DOER DSVS series PWM IGBT Static Voltage Stabilizer is the best generation of stabilizer to handle with.
with an experience of more than 13 years in the industry, our IGBT static voltage stabilizer can deliver a desirable voltage value to meet various application demands in voltage accuracy of +/-1% to optimal of 0.5%. DOER DSVS series IGBT static voltage stabilizer are designed and manufactured with new technology and quality components to prevent all types of your electrical appliances from voltage fluctuations.
