3 Phase UPS Systems

Ideal for marine, industrial applications and Data Centre Applications 3 phase UPS systems really pack a punch in terms of power protection. Unlike single-phase UPS that is designed for smaller, more confined applications, three phase ups systems have been designed to handle high-rated power applications, spread across the enterprise, reliably and with ease.

UPS three-phase systems operate at high efficiency and in double conversion mode for additional reliability. They can be installed in parallel N+1 configurations to enhance system resilience and ensure no single point of failure in the system. Paralleling in this way is also scalable as each UPS in the system is a module in its own right; as your application expands, so too can your UPS system.

Critical Power Projects supplies a variety of sizes (10kVA to 200kVA) of UPS three-phase solutions from the leading manufacturers across the globe. We are independent from our manufacturers so are free to choose the best products for your specific solution.

Modern three-phase UPS designs also cater for different installation requirements and are floor standing, rack-mounted or modular, which can be adapted and suited to the amount of space you have to dedicate to your power protection solution.

If you would like to know more about our range of 3 phase UPS systems, or if you would like impartial advice on UPS, a site survey or quotation, please call: 0808 503 8777, fill in our contacts form or send us an email with your details, and we’ll call you.
