The use of UPS power supply has become the key to protect important equipment. At present, most hospitals have equipped some important equipment with corresponding UPS power supply. Therefore, it is a very important job to equip medical equipment with suitable UPS power supply. Basic characteristics of UPS power supply for medical equipment. 1. With small internal resistance, high precision and strong anti-interference ability, UPS is suitable for large medical equipment. 2. Digital signal processor technology. Adopting the most advanced digital control technology of DSP in the world can effectively ensure the accurate and fast operation of UPS core system. The product performance is more stable. 3. Advanced phase balance technology. Using the current advanced phase balance technology, it has good stability and can work normally even in the absence of phase, especially suitable for many areas with poor power environment. 4. The built-in isolation transformer avoids the input interference of external equipment, which makes the UPS have strong short-circuit protection ability and overload ability, and also greatly improves the safety and stability of the load. 5. The diesel generator that can be connected completely meets the requirement that large precision equipment can work normally under the power supply mode of diesel generator set.
