This exciting new addition to the Sentinel Dual series complements the existing range of 5-10 kVA power solutions. 

The SDU 4000 has an output power factor of 0.9 (4 kVA = 3.6 kW) and offers exceptional online double conversion protection to ensure maximum reliability.  

It’s certain to become a popular and dependable choice for protecting critical IT and server applications, along with electro-medical devices. 

The highly-versatile single-phase UPS power supply is suitable for either tower or rack installation and delivers up to 95% operational efficiency (98% in ECO operating mode).  

The SDU 4000 is latest in several recent expansions to the Sentinel Dual family, following on from the SDU 8000 TM and SDU 10000 TM, two models able to run off either single-phase or three-phase power input.
