The LSP-5KVAS PWM Type AC Power Supply has the characteristics of ultra-low output voltage distortion and configurable output current protection value. It is specially developed for home appliances, motors, compressors and other industries. Used to replace traditional voltage regulators and frequency converters to provide efficient, low-cost, and accurate testing solutions. It has four wheels and easy to move to the different rooms.<\/p>\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n
