S4K2U-C and S4K2U-5C Industrial On-Line UPS
The new SolaHD S4KC is a single-phase, on-line (double-
conversion) UPS system available in 700-3000VA, 120V and
230V. On-Line design means zero transfer time from external
to internal power. When utility power fails, your critical load
remains supported by a seamless ow of power. Rack or
tower congurable, the SolaHD S4KC UPS offers customers
a higher power factor, longer battery life, higher reliability and
reduced cost of ownership. Housed in a slim 2U package,
the SolaHD S4KC protects equipment from virtually all power
disturbances due to blackouts, brownouts, sags, surges or
noise interference. The UPS includes internal batteries.
Optional, matching external battery cabinets, also in a slim
2U (3.5") size, offer extended battery runtime.
The LED display indicates battery capacity, percentage of
UPS load, battery operation, bypass operation and UPS
fault condition.
The rack-tower models are also supplied with securing
anges and rack slide mounting hardware is available
separately, if required. Units can be easily hardwired by
removing the attached line cord and receptacle plate. All
units include a conduit knockout cover in the box.
