Prostar Mars series modular UPS system is non-isolated, industrial level, green UPS, adopting advanced modular power protection concept. Prostar Mars series modular UPS architecture can scale power as demand grows or as higher levels of availability are required. Mars series modular UPS is industry-leading efficiency, availability, and performance for small, medium, and large data centers and mission critical environments.

Thanks to its modular and scalable design as well as its hot-swappable functionality, Prostar MPS40K-30U 3 phase modular ups system 40 kVA for data center can start with a basic configuration of just 20 kVA / 20 kW and then grow gradually as required, up to 200 kVA. Prostar MPS40K-30U 3 phase modular ups system 40 kVA for data center offers input PF >0.99 and input THDi <3 %, even when a low percentage of load is applied.
