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

Order Notes:
\n1. The US standards countires can special designed the input voltage. Such as Single Phase input and Single Phase output LSP-10KVASUS means both input and output are 110V\u00b110%;
\n2. Such as 3Phases input and 3Phases output LSP-15KVASUST means both input and output are 220V\u00b110%<\/span><\/p>\n
