At present, there are many types of regulated power supplies on the market, such as electronic regulators, AC compensating regulators, CNC contactless regulators, etc. When telling about regulated power supplies, attention should be paid to the following aspects
The response time of the power supply and voltage regulator will be directly reflected in the medical equipment. The SBW-W series CNC contactless voltage regulator from Shanghai Voltage Regulator Factory has an electronic module structure inside. It uses sine energy divider technology to achieve voltage regulator control by controlling the conduction angle of the thyristor, integrating voltage regulation and anti-interference. Its response speed of 4ms/step is currently the fastest among all AC voltage regulators. The general mechanical voltage regulator uses the rotation of the motor to drive the carbon brush to slide back and forth on the autotransformer to achieve voltage stabilization. Its production cost is relatively low, economical and practical, and can meet the voltage stabilization requirements of most equipment. However, in terms of response speed, the SBW-W series CNC contactless voltage regulator undoubtedly has the advantage. It is usually applied to the voltage stabilization work of high-precision equipment such as B-ultrasound and hemodialysis machines In the selection process, the voltage stabilization accuracy needs to be considered. The most traditional mechanical voltage regulator has a stabilization accuracy of ± 2%. In recent years, Shanghai Voltage Regulator Factory has developed a high-precision silent voltage regulator - a contactless voltage regulator with high-tech core technology. The accuracy can be as high as 0.5 ± 1%. Generally, PET, DR, CT, MR nuclear magnetic resonance instruments and other instruments require high voltage stabilization accuracy. In this case, it is recommended to choose a CNC contactless voltage regulator. It can quickly solve voltage instability
