Retrofit

Retrofitting Strategy	Replacement of more energy efficient uninterrupted power system (UPS)
	UPS is a continuously operating system that provides reliable power supply to the critical equipment especially IT servers. Higher efficiency UPS can lower the power loss substantially.
	Consideration
	Using insulated-gate bipolar transistor (IGBT) rectifier with power factor correction to ensure that current distortion is lower and power factor >0.99 Using transformerless UPS that improves the energy efficiency Using Modular UPS to improve the flexibility
