S4K2U-C and S4K2U-5C Industrial On-Line UPS
The SolaHD S4KC Series is a single phase, on-line
(doubleconversion) UPS system available in 700-3000 VA,
120 V and 230 V. 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 congurable, the S4KC Series 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.
