S4K 4U (6 kVA) and 6U (10 kVA) Industrial Online UPS

The S4K4U6000 and the S4K6U10000 Industrial UPS Series are the first true on-line industrial UPS that provide flexible output voltage, an integrated maintenance bypass switch and internal batteries all in a slim 4U (7.0”) and 6U (10.5") enclosures.

Both series feature double conversion topology providing the ultimate in protection against a wide range of potential power problems. The S4K4U design of two 3 kVA, 120V inverters inverters allow flexible output voltage to meet mixed load voltage requirements. The UPS automatically configures the output voltage to match the input configuration without requiring tap selections. Self diagnostics simplify maintenance and troubleshooting, and the UPS can be serviced by the customer. The standard maintenance bypass switch provides an additional level of protection.

The S4K4U and S4K6U also feature wide input voltage windows to support the critical load without having to transfer to the battery. This extends system availability when back-up is truly needed.
