The family of S4K UPS eliminate a wider range of potential power problems (spikes, surges and extended overvoltage, noise and other transients, sags and extended brownouts), even difficult-to-track harmonics and dangerous frequency variations that are common with standby generator operation.

The S4K Industrial UPS modules are a true on-line design with a sinewave output in compact package that provide the highest levels of power protection, conditioning and power availability. True on-line topology is accomplished with double conversion technology. Network communications are often necessary to protect mission-critical applications.

The LED display indicates annunciation of battery capacity, percentage of UPS load, battery operation, bypass operation and UPS fault condition. The rack-tower models are also supplied with securing flanges and rack slide mounting hardware.

Uninterruptible power supplies units can be easily hardwired by removing the attached line cord and receptacle plate. All S4K Industrial UPS models include a conduit knockout cover in the box.
