DHF RT SERIES UPS
Range: 1 kVA to 20 kVA (1:1/3:1)
The DHF RT Series rack-mounted UPS offers dependable backup power for
essential equipment in space-constrained settings. Available in single-phase options
(1-10 kVA) and three-phase options (10-20 kVA), the RT Series guarantees continuous
operation of servers, networking gear, and data storage during power outages. Its compact
design fits standard 19-inch racks, making it suitable for network closets, distribution
frames, and small offices. DHF RT series provides effective surge protection, prolongs
hardware lifespan, and supports remote management. Additionally, DHF RT Series
reduces reactive power, improves energy efficiency, and ensures business
continuity. Its flexible battery configurations support 16 to 20 batteries with digitally
controlled charging to maintain optimal battery health.
