In China, a tertiary hospital deployed Mingch's high-precision fully automatic voltage stabilizers in the CT room and X-ray room to stabilize the normal operation of SIEMENS CT machines and other testing instruments in the testing room. Five high-precision high-power voltage stabilizers were installed (used to control each testing instrument individually), which completely solved the problem of equipment damage caused by unstable voltage, reduced maintenance costs by 80%, and greatly improved user satisfaction.
